presentation on pollution for class 5

ELA  /  5th Grade  /  Unit 3: Protecting the Earth: Plastic Pollution

Protecting the Earth: Plastic Pollution

Students explore how plastic pollution is choking the world’s oceans, and explore a variety of solutions for reducing plastic waste and reducing the amount of plastic that ends up in the ocean.

• Text and Materials

Unit Summary

In this unit, students explore how plastic pollution is choking the world’s oceans. Students first learn about the history of plastic, how plastic ends up in the ocean, how plastic in the ocean impacts the ecosystem, and why it’s so hard to remove plastic from the ocean once it’s there. Students then explore a variety of solutions for reducing plastic waste and reducing the amount of plastic that ends up in the ocean. Students will learn about large policy-based changes that can be made and also explore smaller voluntary actions they can take that will make a difference. Finally, students end the unit by doing a research project aimed at educating others about the dangers of plastic and its impact on the environment. 

In this informational unit, students will be challenged to explain the relationship between two or more scientific ideas, noticing how authors use description, sequence, or cause- and-effect paragraph structure to help readers notice and explain the connections between events. Students will also analyze how authors use a variety of reasons and evidence to support their points, depending on their purpose for writing the text.  

Throughout the unit, students learn how to prepare for class discussions, determining which evidence best supports a particular idea and how to elaborate on that evidence. By writing daily in response to the Target Task question, students build their writing fluency, seeing the power of writing as a tool for understanding what they are reading. Students also set the foundations for strong literary analysis and opinion writing by learning how to craft strong paragraphs and multiple-paragraph essays.

Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants.

Pollution is the introduction of harmful materials into the environment . These harmful materials are called pollutants . Pollutants can be natural, such as volcanic ash . They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land. Many things that are useful to people produce pollution. Cars spew pollutants from their exhaust pipes. Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides —chemical poisons used to kill weeds and insects— seep into waterways and harm wildlife . All living things—from one-celled microbes to blue whales—depend on Earth ’s supply of air and water. When these resources are polluted, all forms of life are threatened. Pollution is a global problem. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. For example, pesticides and other chemicals have been found in the Antarctic ice sheet . In the middle of the northern Pacific Ocean, a huge collection of microscopic plastic particles forms what is known as the Great Pacific Garbage Patch . Air and water currents carry pollution. Ocean currents and migrating fish carry marine pollutants far and wide. Winds can pick up radioactive material accidentally released from a nuclear reactor and scatter it around the world. Smoke from a factory in one country drifts into another country. In the past, visitors to Big Bend National Park in the U.S. state of Texas could see 290 kilometers (180 miles) across the vast landscape . Now, coal-burning power plants in Texas and the neighboring state of Chihuahua, Mexico have spewed so much pollution into the air that visitors to Big Bend can sometimes see only 50 kilometers (30 miles). The three major types of pollution are air pollution , water pollution , and land pollution . Air Pollution Sometimes, air pollution is visible . A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible . Polluted air can be dangerous, even if the pollutants are invisible. It can make people’s eyes burn and make them have difficulty breathing. It can also increase the risk of lung cancer . Sometimes, air pollution kills quickly. In 1984, an accident at a pesticide plant in Bhopal, India, released a deadly gas into the air. At least 8,000 people died within days. Hundreds of thou sands more were permanently injured. Natural disasters can also cause air pollution to increase quickly. When volcanoes erupt , they eject volcanic ash and gases into the atmosphere . Volcanic ash can discolor the sky for months. After the eruption of the Indonesian volcano of Krakatoa in 1883, ash darkened the sky around the world. The dimmer sky caused fewer crops to be harvested as far away as Europe and North America. For years, meteorologists tracked what was known as the “equatorial smoke stream .” In fact, this smoke stream was a jet stream , a wind high in Earth’s atmosphere that Krakatoa’s air pollution made visible. Volcanic gases , such as sulfur dioxide , can kill nearby residents and make the soil infertile for years. Mount Vesuvius, a volcano in Italy, famously erupted in 79, killing hundreds of residents of the nearby towns of Pompeii and Herculaneum. Most victims of Vesuvius were not killed by lava or landslides caused by the eruption. They were choked, or asphyxiated , by deadly volcanic gases. In 1986, a toxic cloud developed over Lake Nyos, Cameroon. Lake Nyos sits in the crater of a volcano. Though the volcano did not erupt, it did eject volcanic gases into the lake. The heated gases passed through the water of the lake and collected as a cloud that descended the slopes of the volcano and into nearby valleys . As the toxic cloud moved across the landscape, it killed birds and other organisms in their natural habitat . This air pollution also killed thousands of cattle and as many as 1,700 people. Most air pollution is not natural, however. It comes from burning fossil fuels —coal, oil , and natural gas . When gasoline is burned to power cars and trucks, it produces carbon monoxide , a colorless, odorless gas. The gas is harmful in high concentrations , or amounts. City traffic produces highly concentrated carbon monoxide. Cars and factories produce other common pollutants, including nitrogen oxide , sulfur dioxide, and hydrocarbons . These chemicals react with sunlight to produce smog , a thick fog or haze of air pollution. The smog is so thick in Linfen, China, that people can seldom see the sun. Smog can be brown or grayish blue, depending on which pollutants are in it. Smog makes breathing difficult, especially for children and older adults. Some cities that suffer from extreme smog issue air pollution warnings. The government of Hong Kong, for example, will warn people not to go outside or engage in strenuous physical activity (such as running or swimming) when smog is very thick.

When air pollutants such as nitrogen oxide and sulfur dioxide mix with moisture, they change into acids . They then fall back to earth as acid rain . Wind often carries acid rain far from the pollution source. Pollutants produced by factories and power plants in Spain can fall as acid rain in Norway. Acid rain can kill all the trees in a forest . It can also devastate lakes, streams, and other waterways. When lakes become acidic, fish can’t survive . In Sweden, acid rain created thousands of “ dead lakes ,” where fish no longer live. Acid rain also wears away marble and other kinds of stone . It has erased the words on gravestones and damaged many historic buildings and monuments . The Taj Mahal , in Agra, India, was once gleaming white. Years of exposure to acid rain has left it pale. Governments have tried to prevent acid rain by limiting the amount of pollutants released into the air. In Europe and North America, they have had some success, but acid rain remains a major problem in the developing world , especially Asia. Greenhouse gases are another source of air pollution. Greenhouse gases such as carbon dioxide and methane occur naturally in the atmosphere. In fact, they are necessary for life on Earth. They absorb sunlight reflected from Earth, preventing it from escaping into space. By trapping heat in the atmosphere, they keep Earth warm enough for people to live. This is called the greenhouse effect . But human activities such as burning fossil fuels and destroying forests have increased the amount of greenhouse gases in the atmosphere. This has increased the greenhouse effect, and average temperatures across the globe are rising. The decade that began in the year 2000 was the warmest on record. This increase in worldwide average temperatures, caused in part by human activity, is called global warming . Global warming is causing ice sheets and glaciers to melt. The melting ice is causing sea levels to rise at a rate of two millimeters (0.09 inches) per year. The rising seas will eventually flood low-lying coastal regions . Entire nations, such as the islands of Maldives, are threatened by this climate change . Global warming also contributes to the phenomenon of ocean acidification . Ocean acidification is the process of ocean waters absorbing more carbon dioxide from the atmosphere. Fewer organisms can survive in warmer, less salty waters. The ocean food web is threatened as plants and animals such as coral fail to adapt to more acidic oceans. Scientists have predicted that global warming will cause an increase in severe storms . It will also cause more droughts in some regions and more flooding in others. The change in average temperatures is already shrinking some habitats, the regions where plants and animals naturally live. Polar bears hunt seals from sea ice in the Arctic. The melting ice is forcing polar bears to travel farther to find food , and their numbers are shrinking. People and governments can respond quickly and effectively to reduce air pollution. Chemicals called chlorofluorocarbons (CFCs) are a dangerous form of air pollution that governments worked to reduce in the 1980s and 1990s. CFCs are found in gases that cool refrigerators, in foam products, and in aerosol cans . CFCs damage the ozone layer , a region in Earth’s upper atmosphere. The ozone layer protects Earth by absorbing much of the sun’s harmful ultraviolet radiation . When people are exposed to more ultraviolet radiation, they are more likely to develop skin cancer, eye diseases, and other illnesses. In the 1980s, scientists noticed that the ozone layer over Antarctica was thinning. This is often called the “ ozone hole .” No one lives permanently in Antarctica. But Australia, the home of more than 22 million people, lies at the edge of the hole. In the 1990s, the Australian government began an effort to warn people of the dangers of too much sun. Many countries, including the United States, now severely limit the production of CFCs. Water Pollution Some polluted water looks muddy, smells bad, and has garbage floating in it. Some polluted water looks clean, but is filled with harmful chemicals you can’t see or smell. Polluted water is unsafe for drinking and swimming. Some people who drink polluted water are exposed to hazardous chemicals that may make them sick years later. Others consume bacteria and other tiny aquatic organisms that cause disease. The United Nations estimates that 4,000 children die every day from drinking dirty water. Sometimes, polluted water harms people indirectly. They get sick because the fish that live in polluted water are unsafe to eat. They have too many pollutants in their flesh. There are some natural sources of water pollution. Oil and natural gas, for example, can leak into oceans and lakes from natural underground sources. These sites are called petroleum seeps . The world’s largest petroleum seep is the Coal Oil Point Seep, off the coast of the U.S. state of California. The Coal Oil Point Seep releases so much oil that tar balls wash up on nearby beaches . Tar balls are small, sticky pieces of pollution that eventually decompose in the ocean.

Human activity also contributes to water pollution. Chemicals and oils from factories are sometimes dumped or seep into waterways. These chemicals are called runoff. Chemicals in runoff can create a toxic environment for aquatic life. Runoff can also help create a fertile environment for cyanobacteria , also called blue-green algae . Cyanobacteria reproduce rapidly, creating a harmful algal bloom (HAB) . Harmful algal blooms prevent organisms such as plants and fish from living in the ocean. They are associated with “ dead zones ” in the world’s lakes and rivers, places where little life exists below surface water. Mining and drilling can also contribute to water pollution. Acid mine drainage (AMD) is a major contributor to pollution of rivers and streams near coal mines . Acid helps miners remove coal from the surrounding rocks . The acid is washed into streams and rivers, where it reacts with rocks and sand. It releases chemical sulfur from the rocks and sand, creating a river rich in sulfuric acid . Sulfuric acid is toxic to plants, fish, and other aquatic organisms. Sulfuric acid is also toxic to people, making rivers polluted by AMD dangerous sources of water for drinking and hygiene . Oil spills are another source of water pollution. In April 2010, the Deepwater Horizon oil rig exploded in the Gulf of Mexico, causing oil to gush from the ocean floor. In the following months, hundreds of millions of gallons of oil spewed into the gulf waters. The spill produced large plumes of oil under the sea and an oil slick on the surface as large as 24,000 square kilometers (9,100 square miles). The oil slick coated wetlands in the U.S. states of Louisiana and Mississippi, killing marsh plants and aquatic organisms such as crabs and fish. Birds, such as pelicans , became coated in oil and were unable to fly or access food. More than two million animals died as a result of the Deepwater Horizon oil spill. Buried chemical waste can also pollute water supplies. For many years, people disposed of chemical wastes carelessly, not realizing its dangers. In the 1970s, people living in the Love Canal area in Niagara Falls, New York, suffered from extremely high rates of cancer and birth defects . It was discovered that a chemical waste dump had poisoned the area’s water. In 1978, 800 families living in Love Canal had to a bandon their homes. If not disposed of properly, radioactive waste from nuclear power plants can escape into the environment. Radioactive waste can harm living things and pollute the water. Sewage that has not been properly treated is a common source of water pollution. Many cities around the world have poor sewage systems and sewage treatment plants. Delhi, the capital of India, is home to more than 21 million people. More than half the sewage and other waste produced in the city are dumped into the Yamuna River. This pollution makes the river dangerous to use as a source of water for drinking or hygiene. It also reduces the river’s fishery , resulting in less food for the local community. A major source of water pollution is fertilizer used in agriculture . Fertilizer is material added to soil to make plants grow larger and faster. Fertilizers usually contain large amounts of the elements nitrogen and phosphorus , which help plants grow. Rainwater washes fertilizer into streams and lakes. There, the nitrogen and phosphorus cause cyanobacteria to form harmful algal blooms. Rain washes other pollutants into streams and lakes. It picks up animal waste from cattle ranches. Cars drip oil onto the street, and rain carries it into storm drains , which lead to waterways such as rivers and seas. Rain sometimes washes chemical pesticides off of plants and into streams. Pesticides can also seep into groundwater , the water beneath the surface of the Earth. Heat can pollute water. Power plants, for example, produce a huge amount of heat. Power plants are often located on rivers so they can use the water as a coolant . Cool water circulates through the plant, absorbing heat. The heated water is then returned to the river. Aquatic creatures are sensitive to changes in temperature. Some fish, for example, can only live in cold water. Warmer river temperatures prevent fish eggs from hatching. Warmer river water also contributes to harmful algal blooms. Another type of water pollution is simple garbage. The Citarum River in Indonesia, for example, has so much garbage floating in it that you cannot see the water. Floating trash makes the river difficult to fish in. Aquatic animals such as fish and turtles mistake trash, such as plastic bags, for food. Plastic bags and twine can kill many ocean creatures. Chemical pollutants in trash can also pollute the water, making it toxic for fish and people who use the river as a source of drinking water. The fish that are caught in a polluted river often have high levels of chemical toxins in their flesh. People absorb these toxins as they eat the fish. Garbage also fouls the ocean. Many plastic bottles and other pieces of trash are thrown overboard from boats. The wind blows trash out to sea. Ocean currents carry plastics and other floating trash to certain places on the globe, where it cannot escape. The largest of these areas, called the Great Pacific Garbage Patch, is in a remote part of the Pacific Ocean. According to some estimates, this garbage patch is the size of Texas. The trash is a threat to fish and seabirds, which mistake the plastic for food. Many of the plastics are covered with chemical pollutants. Land Pollution Many of the same pollutants that foul the water also harm the land. Mining sometimes leaves the soil contaminated with dangerous chemicals. Pesticides and fertilizers from agricultural fields are blown by the wind. They can harm plants, animals, and sometimes people. Some fruits and vegetables absorb the pesticides that help them grow. When people consume the fruits and vegetables, the pesticides enter their bodies. Some pesticides can cause cancer and other diseases. A pesticide called DDT (dichlorodiphenyltrichloroethane) was once commonly used to kill insects, especially mosquitoes. In many parts of the world, mosquitoes carry a disease called malaria , which kills a million people every year. Swiss chemist Paul Hermann Muller was awarded the Nobel Prize for his understanding of how DDT can control insects and other pests. DDT is responsible for reducing malaria in places such as Taiwan and Sri Lanka. In 1962, American biologist Rachel Carson wrote a book called Silent Spring , which discussed the dangers of DDT. She argued that it could contribute to cancer in humans. She also explained how it was destroying bird eggs, which caused the number of bald eagles, brown pelicans, and ospreys to drop. In 1972, the United States banned the use of DDT. Many other countries also banned it. But DDT didn’t disappear entirely. Today, many governments support the use of DDT because it remains the most effective way to combat malaria. Trash is another form of land pollution. Around the world, paper, cans, glass jars, plastic products, and junked cars and appliances mar the landscape. Litter makes it difficult for plants and other producers in the food web to create nutrients . Animals can die if they mistakenly eat plastic. Garbage often contains dangerous pollutants such as oils, chemicals, and ink. These pollutants can leech into the soil and harm plants, animals, and people. Inefficient garbage collection systems contribute to land pollution. Often, the garbage is picked up and brought to a dump, or landfill . Garbage is buried in landfills. Sometimes, communities produce so much garbage that their landfills are filling up. They are running out of places to dump their trash. A massive landfill near Quezon City, Philippines, was the site of a land pollution tragedy in 2000. Hundreds of people lived on the slopes of the Quezon City landfill. These people made their living from recycling and selling items found in the landfill. However, the landfill was not secure. Heavy rains caused a trash landslide, killing 218 people. Sometimes, landfills are not completely sealed off from the land around them. Pollutants from the landfill leak into the earth in which they are buried. Plants that grow in the earth may be contaminated, and the herbivores that eat the plants also become contaminated. So do the predators that consume the herbivores. This process, where a chemical builds up in each level of the food web, is called bioaccumulation . Pollutants leaked from landfills also leak into local groundwater supplies. There, the aquatic food web (from microscopic algae to fish to predators such as sharks or eagles) can suffer from bioaccumulation of toxic chemicals. Some communities do not have adequate garbage collection systems, and trash lines the side of roads. In other places, garbage washes up on beaches. Kamilo Beach, in the U.S. state of Hawai'i, is littered with plastic bags and bottles carried in by the tide . The trash is dangerous to ocean life and reduces economic activity in the area. Tourism is Hawai'i’s largest industry . Polluted beaches discourage tourists from investing in the area’s hotels, restaurants, and recreational activities. Some cities incinerate , or burn, their garbage. Incinerating trash gets rid of it, but it can release dangerous heavy metals and chemicals into the air. So while trash incinerators can help with the problem of land pollution, they sometimes add to the problem of air pollution. Reducing Pollution Around the world, people and governments are making efforts to combat pollution. Recycling, for instance, is becoming more common. In recycling, trash is processed so its useful materials can be used again. Glass, aluminum cans, and many types of plastic can be melted and reused . Paper can be broken down and turned into new paper. Recycling reduces the amount of garbage that ends up in landfills, incinerators, and waterways. Austria and Switzerland have the highest recycling rates. These nations recycle between 50 and 60 percent of their garbage. The United States recycles about 30 percent of its garbage. Governments can combat pollution by passing laws that limit the amount and types of chemicals factories and agribusinesses are allowed to use. The smoke from coal-burning power plants can be filtered. People and businesses that illegally dump pollutants into the land, water, and air can be fined for millions of dollars. Some government programs, such as the Superfund program in the United States, can force polluters to clean up the sites they polluted. International agreements can also reduce pollution. The Kyoto Protocol , a United Nations agreement to limit the emission of greenhouse gases, has been signed by 191 countries. The United States, the world’s second-largest producer of greenhouse gases, did not sign the agreement. Other countries, such as China, the world’s largest producer of greenhouse gases, have not met their goals. Still, many gains have been made. In 1969, the Cuyahoga River, in the U.S. state of Ohio, was so clogged with oil and trash that it caught on fire. The fire helped spur the Clean Water Act of 1972. This law limited what pollutants could be released into water and set standards for how clean water should be. Today, the Cuyahoga River is much cleaner. Fish have returned to regions of the river where they once could not survive. But even as some rivers are becoming cleaner, others are becoming more polluted. As countries around the world become wealthier, some forms of pollution increase. Countries with growing economies usually need more power plants, which produce more pollutants. Reducing pollution requires environmental, political, and economic leadership. Developed nations must work to reduce and recycle their materials, while developing nations must work to strengthen their economies without destroying the environment. Developed and developing countries must work together toward the common goal of protecting the environment for future use.

How Long Does It Last? Different materials decompose at different rates. How long does it take for these common types of trash to break down?

Indoor Air Pollution The air inside your house can be polluted. Air and carpet cleaners, insect sprays, and cigarettes are all sources of indoor air pollution.

Light Pollution Light pollution is the excess amount of light in the night sky. Light pollution, also called photopollution, is almost always found in urban areas. Light pollution can disrupt ecosystems by confusing the distinction between night and day. Nocturnal animals, those that are active at night, may venture out during the day, while diurnal animals, which are active during daylight hours, may remain active well into the night. Feeding and sleep patterns may be confused. Light pollution also indicates an excess use of energy. The dark-sky movement is a campaign by people to reduce light pollution. This would reduce energy use, allow ecosystems to function more normally, and allow scientists and stargazers to observe the atmosphere.

Noise Pollution Noise pollution is the constant presence of loud, disruptive noises in an area. Usually, noise pollution is caused by construction or nearby transportation facilities, such as airports. Noise pollution is unpleasant, and can be dangerous. Some songbirds, such as robins, are unable to communicate or find food in the presence of heavy noise pollution. The sound waves produced by some noise pollutants can disrupt the sonar used by marine animals to communicate or locate food.

Pollution and Calamities

5th Class Science Pollution and Calamities

Category : 5th Class

POLLUTION AND CALAMITIES

FUNDAMENTAL

Pollution is deterioration of environment due unwanted and undesirable substances present leading to affect health and day to day life.

Unwanted and undesirable substances present in air, water, and soil are pollutants such as sulphur dioxide (SO 2 ), lead oxides, smoke dust particles   etc.

AIR POLLUTION → CAUSES                

• Burning of fossil fuel.
• Smoke from factories.
• Release of harmful gases from cars and other vehicles.
• Deforestation
• Volcanic eruption
• Forest fire

            Deforestation is the major cause of Air pollution as plants and trees act as natural purifiers.

            Volcanic eruptions causes concentration of carbon dioxide, nitrogen oxide and sulphur dioxide.       

Consequences of air pollution

• Acid rain- Acid rain occurs when sulphur di-oxide \[(S{{O}_{2}})\] nitric oxide \[(N{{O}_{2}})\] mixes with rain water forming sulphuric acid \[({{H}_{2}}S{{O}_{4}})\] and nitric acid\[(HN{{O}_{3}})\] . It can corrode buildings and statues Taj Mahal corroded due to acid rain.
• Green house effect - Gradual warming of the earth atmosphere due to absorption of infrared radiation. By\[C{{O}_{2}}\], water vapors, methane, nitrous oxide and chlorofloro carbon, flue carbon.
• Ozone depletion- carbon dioxide protects the ozone layer, by preventing the formation of nitrogen oxide. Which saves us from the harm full effect of ultraviolet radiations from sun.

Effect of air pollution   

• It causes itching and irritation to eye, skin, nose throat, and respiratory tract.
• Many respiratory problems like asthma, bronchi's, occurs may due to air pollution.
• Injurious to plant and other animals also.
• Due to presence of smoke, dust and vapour visibility decreases.
• Air pollution may cause cancer and neurological disorder.

Methods to minimize the air pollution

• Safer fuels CNG in place of diesel and petrol.
• Factory and industries should installed filters, chimneys chemical catalysts to purify fume.
• Plantation of trees
• Renewable energy source promotion.
• Plastic materials use should be reduced, recycled, reuse.

WATER POLLUTION:-

Water is universal solvent as it dissolves maximum substances. Due to human activities over, industrialisation and unawareness the smell and quality of water is being compromised which is called water pollution.

• Dumping of factories and household waste in river.
• Unwanted and continuous growth of algae, zooplanktons over the surface of pond water preventing light to go deep.
• Throwing of dead bodies of animals.
• Washing of clothes with detergents and throwing wastes into river.
• Release of insecticides, pesticides, and harmful fertilizers (nitrate and sulphates) along with rain water or wind etc.
• Sewage and petrochemical spills.

Consequence of water pollution

• Killing of fishes and other aquatic lives
• Affects oxygen content of water bodies leading to respiratory inability of aquatic lives.
• Disturbance of food chain due to killing of aquatic lives.
• Plant productivity will be reduced.
• Eutrophication this process fill the water body with organic and other wastes.
• Pathogens enter human body through polluted water and causes typhoid, dysentery, cholera and skin diseases.

Prevention of water pollution                               

• High alertness and self-consciousness can prevent water to be polluted.
• Use of electric vehicles to avoid nitrogen waste from automobile exhaust.
• Pesticides and chemical not to be allowed to reach water body.
• Human and animals wastes to be prevented to entering river.
• Avoid bathing and throwing of dead in a water bodies.

SOIL POLLUTION

Excessive unorganized agriculture and non-judicious use of chemical fertilizer, pesticides, weedicide herbicides and insecticide contaminate the soil, which is called soil pollution.

• Harmful toxic chemical are released from underground pipe on soil.
• Acid rain when rain fall on the soil degrades its quality.
• Excessive use of fertilizers (chemical) again and again on same soil.
• Unfavorable irrigation practices.
• Wastes toxic chemical released from industries in the ground.
• Presence of non-biodegradable substances (Plastic, polythene) etc. degrade soil quality.
• Spraying of Pesticide, weedicides, herbicides etc. deteriorate the quality of soil.

Consequence of soil pollution                                                 

• Disturbance of food chain and web existing in soil.
• Plant are reduced dust reduced soil fertility.
• Soil erosion dust reduced vegetation.
• Migration of animal living in soil to another place due to shortage of food.
• Polluted soil causes disease.

            (a) Cholera and dysentery are caused when soil pollutant reaches water sources.

            (b) Brain and nervous disorder when the pollution    disturbs neuromuscular growth and development.

            (c) Cancer due to chemical carcinogen due to spray of insecticides.

Step to maintain the quality of soil

• Maximum use of biological manures like cow dung instead of fertilizes.
• Use of organic fertilizers
• Contaminant soil should be taken away excavation.
• Crop rotation mixed cropping etc. should be in practice to restore soil fertility.

NOISE - POLLUTION

It is the loud unwanted and undesired sound. Sound > 80dB (decibel) given unpleasant experience and regarded as noise pollution 90% of noise pollution is due to the noise produced by the motor vehicles.

• Construction works
• Factories industries
• Transport – modes
• Explosion in mining

Some important sound intensity:-

• Normal talking -  40dB
• Whispering -  20dB
• Aircraft -  120dB
• Atomic explosion -  200dB

Consequences of noise pollution                                     

• Temporary or permanent deafness due to prolonged exposes of noise.
• Sleep disturbance restlessness, headache and lethargic feeling.
• Affects plant's growth.
• Reduces learning and reading skill.
• Weakens building and bridges.
• Cause stress and Hypertension, mental agony.

Protection form noise pollution                        

• Education regarding noise pollution.
• Sound proofing and sound muffling systems.
• Tree plantation around high ways and roads in residential areas.
• Avoidance of high intensity sound for longer time and use of automation at these sites.

NATURAL CALAMITIES / DISASTER

Earthquake                           

An earthquake is a sudden shaking of the ground     caused by the movements or vibrations deep inside the earth. The earth's upper layer, the crust, is made of large and small plates. The layers of earth under the plates are hot and in a molten state, as the core inside are extremely hot and moving. These movements cause the plates to slide smoothly against each other. These movements can sometimes give rise to earthquake when the ground shakes, houses, building and bridges shake. When it lasts for longer time roads crack, structures shatter and communication system collapse leading to loss of life and property. Earthquake is measured on Richter's scale. People who study earthquake are called seismologist earthquake can be detected with an instrument called seismograph.

Is an opening in earth's surface which allows hot, molten rock ash and gases to escape form below the surface? These burst out of the crest at the top or holes around the sides of the volcano through weak point some volcanoes are formed under the sea. When the lava cools down, the area formed cools like a new island. The barren island is the only active volcano in the Indian subcontinent, located in Andaman and Nicobar Island.

Tidal waves

Very high Tidal waves are called tsunami. Tsunami are caused by undersea earthquake or by the sea come rolling towards the shore and causes distraction on the sea there in seconds. These are already high tides and storm wave hit the land and causes severe damage.

Drought are caused by poor rain fall. Land and water bodies dry up because of severe heat. This causes acute shortage of water for agriculture and domestic use. Because of scarcity of water animals and people suffer from lack of food and drinking water.

• Speech on Air Pollution for Students and Children

Speech on Air Pollution

My Greetings to everybody present over here and thanks for giving your precious time. Today I would like to deliver a speech on Air Pollution which has become a major challenge in recent times. In spite of a monologue, I would like it to be a fruitful interaction, hence your views are welcome. Air pollution means mixing of external hazardous gases and particulate matter in the air, which ultimately route inside our body through inhalation. These gradually lead to respiratory disorders and hence affect the health of human beings. Hence nowadays air pollution is becoming a major concern for humanity.

Causes of Air Pollution

There could be various causes of air pollution in today’s world. The world is developing at the cost of the environment. Today’s society in view of modernization is neglecting the mother nature and thereby adopting the lifestyle which ultimately cost us on our health.

The number of vehicles on road has increased tremendously in the past few decades, hence the emission level has also gone up. This can be very well seen by an increase in ppm-level. The severe pollution level in Delhi is an alarming situation for all of us.

Also, the smoke coming out of factories or the poisonous gases coming out of chemical factories are polluting the air. We have seen one major tragedy of air pollution in the form of Bhopal Gas Tragedy. The increase in usage of Air conditioners in homes is also a cause of air pollution.

Effect of Air Pollution

Also, the different dangerous gases or smoke, when enters the pregnant ladies, cause the unborn child to come in contact with it before taking the birth. These children tend to have a high possibility of respiratory diseases as compared to other children.

The decrease in trees and plants leads to an imbalance in nature. It causes Global warming and depletion of the Ozone layer. Global warming leads to an imbalance of the natural cycle and hence de freezing of polar ice, which is again a foreseen danger. The depletion of the ozone layer allows the infrared rays to enter our atmosphere, thereby causing skin diseases.

The air pollution is affecting the animals as well. It causes acid rains which leads to the death of a lot of animals and marine creatures. Increasing allergic patients nowadays are due to air pollution only. Asthma is affecting the people of all age groups starting from 0 years of age.

Nature is an asset given to us. It has given life to living beings. And to pass on this asset to our offsprings as it is, we need to take good care of it. If we need our future generations to grow up in a healthy environment, then we need to take the steps now.

We need to stop cutting the trees for the sake of the construction of residential colonies or factories. We need to adopt public transports for long distances and bicycles for shorter distances, so as to reduce the smoke and emissions and thereby reducing air pollution. Mother Nature needs to be taken care of well for the flourishing of our upcoming generations. Let’s take a pledge now to respect and protect our environment.

Thank you all for listening and for giving your precious time.

Air its Uses and Pollution Class 5 EVS Chapter Notes

July 12, 2022 by Manjeet Leave a Comment

The chapter “Air its Uses and Pollution” is Chapter 20 from Let’s Look Around and Learn Environmental Studies for students of Class 5th of JKBOSE . This post is precisely about Air its Uses and Pollution Class 5 EVS Chapter Notes. In my last post, you read about Air its Uses and Pollution Class 5 EVS Question Answers . Let’s get started with today’s post:

Introduction

The chapter “Air its Uses and Pollution” details students about properties of air, uses of air and pollution of air. Air is very useful for survival of living things on earth. It is important for us to keep it clean and fresh.

The earth is surrounded by an envelope of air, called the atmosphere. It extends up to a few hundred kilometres above the earth. Air is a mixture of gases like nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium, neon, etc. All living things use oxygen in the air for breathing. Without air, life would be impossible on the earth.

The atmosphere is most dense at sea level. The density of atmospheric air decreases with altitude (height).

Air Exerts Pressure 

Air is a matter and, therefore, has weight. Air exerts pressure because it has weight. Several kilometres high column of air above us exerts tremendous pressure on us. We do not feel this pressure because it acts equally in all directions. We can prove that air exerts pressure through the following activities.

Activity No. 1

Take a glass tumbler and fill it completely with water. Cover the tumbler with thick cardboard with your right hand. Hold the tumbler with the other hand and carefully turn the tumbler upside down. 

What do you see? 

Does the cardboard fall down? 

Does water go out?

You will see that the cardboard does not fall down. It is because that air exerts upward pressure on the cardboard and so the cardboard and water do not fall.

Thus, from the above activity, it is clear that air exerts pressure.

Activity No. 2

Take a narrow tin can. Put some water in it. Heat the water till it starts boiling. Let the water boil for a while. After that close, the mouth of the can lightly. Allow the can to cool. What do you find after some time? You will find that the sides of the can crumble.

The water vapour produced by the boiling water drives away the air contained in the can. When the can is allowed to cool, the vapour condenses to water and a partial vacuum is created inside the can. Now the pressure of the outside air acts on the can and crumbles it.

The above activity shows that for seeing the effect of air pressure, we have only to remove air from a container.

Air Occupies Space and has Weight

To show that air occupies space and has weight, let us perform the following activity:

Take a thin straight stick, two balloons of the same size, a string and a pin. Tie the string to the middle of the stick. Fill both the balloons with air so that both of them are equal in size. Tie the mouths of the two balloons with strings of the same size. Hand the balloons one on each side of the stick as shown in fig. (a). Hold up the string at the centre. 

The stick remains horizontal and the balloons are balanced. Now prick one of the balloons with the pin and allow air to ‘ escape. This end will go up and the other end will come down as shown in fig. (b). The balloon filled with air is heavier than the balloon which has no air. This shows that air occupies space and has weight.

The Uses of Air 

The properties of air like 1. air occupies space, 2. air has weight and 3. air exerts pressure and helps us to perform some of our day-to-day activities. 

• Air can expand certain bodies 

Since air occupies space and exerts pressure, it is therefore used to inflate (expand) things like balloons, air pillows and mattresses.

Balloons and pillows are elastic. When air is filled in them, the pressure of air expands their bodies.

Air can be used to inflate a football bladder or a cycle tube. The football will bounce well because of the pressure of the air inside the bladder.

Air is also used to inflate tubes of cycle, car, bus and lorry tyres. Due to the air pressure on the inner walls of the tyre tube, the bicycle and the other vehicles run smoothly on the road.

• Air pressure can move liquids 

Air pressure is used to draw liquids up in straw, an injection syringe, a medical dropper, an ink-filler, a fountain pen, and the common lift pump.

We use a straw to draw cold drinks from a bottle. One end of the straw is kept in the drink and is sucked through the other end. Owing to this, some air is removed from the straw tube and the air pressure inside it is reduced. Now the outside pressure acting on the surface of the drink forces it up into the straw and then into the mouth.

An injection syringe works with air pressure. The doctor introduces the syringe into the liquid medicine and pushes the piston down pushing the air out. Then he pulls the piston up. The outside air exerts pressure on the surface of the medicine and forces the liquid into the syringe.

Atmospheric pressure presses the liquid into the medicine dropper. The open end of the dropper is dipped into the liquid medicine and the rubber bulb is pressed. The air from the tube of the dropper is forced out and the air pressure inside it is reduced. The outside air pressure presses the liquid medicine into the tube of the dropper. The liquid contained in the dropper can now be emptied.

The fountain pen also works on the same principle.

The medicine dropper can also be used as an ink-filler. The common lift pump works on the same principle as a syringe and it helps to draw water up. There are two valves in a lift pump which open only upward and prevent water from going down.

If you are asked to transfer the kerosene oil from a big container into a beaker. How will you do it?

Take a plastic tube and fill it with kerosene. As shown in the siphon figure, let one end of the rubber tube be dipped in the kerosene and the other end be kept in the beaker. Kerosene will flow speedily and get collected in the beaker. 

In this way, the kerosene from the container can be emptied into the different beakers. Care should be taken to see that the level of kerosene in the container is higher than that in the beaker. The higher the level of the container from which the liquid is transferred, the faster will be the flow of liquid. There should not be any air leakage in the siphon tube.

A siphon is a simple arrangement usually made of glass, plastic, or rubber tube which provides an easy transfer of liquid from a higher level to a lower level. A siphon is, generally, used if the container is too heavy to be lifted, if the container is fixed to a part of a machine or if the container contains liquid sediment.

• Various Constituents of Air 
• Nitrogen: It is the main constituent of air. Air has 78% of oxygen in it. It is required for the normal growth and development of plants. It is an inactive gas, so it serves to dilute the highly active gas, oxygen. Nowadays, fertilizers are prepared from the nitrogen in the air. They increase crop yield.
• Oxygen: It is the active constituent of air. All living things depend on oxygen for respiration. No life can exist on earth without oxygen. It is also essential for burning. 
• Carbon dioxide: It is present in the air in very small amounts. In the presence of sunlight, green plants prepare their food by using this gas. 
• Water vapour: Water vapour in the air is the cause of the dew, clouds, rain, snow and hail.
• Rare gases: Helium, neon, argon, krypton and xenon are known as ‘rare gases’ of air. They are very inactive. Helium is used for filling balloons. Argon and krypton are used for filling electric bulbs. Neon is used inside the brightly coloured advertising lights (neon signs).

Air Pollution

Air is most important for the existence of life on the earth. It is essential for the respiration of both animals and plants. Therefore, the air must pure. When poisonous gases and harmful substances mix with the air and make it impure, the air is said to be polluted.

Air gets polluted by smoke, dust and coke emitted by running automobiles and chimneys of factories. Some common air pollutants which pollute the air are gases like carbon monoxide, carbon dioxide, dust, sulphur dioxide, etc.

Sources of Air Pollution 

Various sources of air pollution are:

• Burning coal, wood, kerosene, petrol, diesel, etc. 
• Exhaust gases from automobiles. 
• Smoke from factories. 
• Smoke, Dirt and dust raised by heavy traffic. 
• Dirt and dust from certain mines. 
• Decaying animal and plant matter in the garbage:

Effect of Air pollution 

Polluted air is harmful and injurious to human health. Some of the harmful effects of inhaling polluted air are:

• Redness and irritation of eyes. 
• Choking sensation in the throat. 
• Difficulty in breathing, bronchitis. 

Tokyo is the most polluted city in the world and Delhi is the most polluted city in India? Other most polluted cities in India are Kolkata, Mumbai and Kanpur.

Control of Air pollution 

The pollution of air can be controlled in the following ways: 

• By using smokeless sources of energy, like solar energy, wind energy etc. 
• By installing very tall chimneys in the factories. 
• By growing more trees.

New Words from Chapter

• Expand: Cause something to become greater in size.
• Garbage: Waste material, especially domestic waste, and agricultural waste.
• Inactive gas: One of the constituents of air thạt dilutes the highly active gas, oxygen.

• Vacuum: The space that is empty of all matter, or gases.
• Weight: Degree of the heaviness of a thing, especially as measured on a balance.
• Air has weight and exerts pressure.
• Air pressure can move liquids.
• Ink-fillers, common lift pumps and siphons operate by using air pressure.
• Air can expand certain bodies.
• Air contains many gases useful to man.
• Living beings breathe in oxygen. Oxygen is needed for combustion.

Each year, the Leadership Tuscarawas class is assigned community projects focused on enhancing the quality of life for people who live and work in Tuscarawas County. Throughout the program, class members work with project partners and other community members to complete their projects. This year’s class worked on six projects. Projects include Tuscarawas Co Senior Ctr Mobility Management plan; COAD Child Care Provider Recruitment; Empower Tusc Suicide Prevention; Tuscarawas County Farmers Market sustainability plan; Tuscarawas Arts Partnership, and Dennison Depot Railroad Museum, Dennison &Ohio Railroad Plan.  Each group will present an overview of their project as part of the evening’s events. Following the presentations, a graduation ceremony will be held with Dean Brad Bielski, Kent State University at Tuscarawas, as the featured speaker.

In addition to working on community projects, Leadership Tuscarawas participants attend monthly program days focused on servant leadership, community awareness and a variety of leadership professional development programs.

During the program, participants have the opportunity to network and learn from each other as well as from many community leaders who are invited to present at monthly program days. Topics of the program days vary and include agriculture, justice, manufacturing, tourism, and government, among others.  Each year, class members take a bus tour of Tuscarawas County, visit local businesses and manufacturers, and tour the Tuscarawas County Jail and Juvenile Attention Center.
