What Is Pollution Assignment Words: 2657

Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollution is Often classed as point source or nonprofit source pollution. Different types of pollution Air Pollution Water Pollution Noise pollution Air Pollution? Air is the ocean we breathe. Air supplies us with oxygen which is essential for our bodies to live. Air is 99. 9% nitrogen, oxygen, water vapor and inert gases. Human activities can release substances into the air, some of which can cause problems for humans, plants, and animals. There are several main types of pollution and well-known effects of pollution which are commonly scudded.

These include smog, acid rain, the greenhouse effect, and “holes” in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment. One type of air pollution is the release of particles into the air from burning fuel for energy. Diesel smoke is a good example of this particulate matter . This type of pollution is sometimes referred to as “black carbon” pollution . The exhaust from burning fuels in automobiles, homes, and industries is a major source of pollution in the air.

Some authorities believe that even the burning of wood ND charcoal in fireplaces and barbeques can release significant quantities of soot into the air. Another type of pollution is the release of noxious gases, such as sulfur dioxide, carbon monoxide, nitrogen oxides, and chemical vapors. These can take part in further chemical reactions once they are in the atmosphere, forming smog and acid rain. How can air pollution affect your health? Air pollution can affect our health in many ways with both short-term and long-term effects. Different groups of individuals are affected by air pollution in different ways.

Some individuals are much more sensitive to pollutants than are others. Young children and elderly people often suffer more from the effects of air pollution. People with health problems such as asthma, heart and lung disease may also suffer more when the air is polluted. The extent to which an individual is harmed by air pollution usually depends on the total exposure to the damaging chemicals, I. E. , the duration of exposure and the concentration of the chemicals must be taken into account. Examples of short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia.

Other symptoms can include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. In the great “Smog Disaster” in London in 1952, four thousand people died in a few days due to the high concentrations of pollution. Long-term health effects can Include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly.

It is estimated that half a million people die prematurely every year in the noted States as a result of smoking cigarettes. How can we prevent air pollution Restricted amounts Of fossil fuels being burnt Less deforestation Be more CEO friendly Don’t use electricity when u don’t need it Water pollution Water pollution is the contamination of water bodies , water pollution occurs when pollutants are discharged directly into water bodies without adequate treatment to remove harmful compounds How does it affect us Virtually all types of water pollution are harmful to the health of humans and animals.

Water pollution may not damage our health immediately but can be harmful after long term exposure. Different forms of pollutants affect the health of animals in different ways: metals from industrial processes can accumulate in nearby lakes and rivers. These are toxic to marine life such as fish and shellfish, and subsequently to the humans who eat them. Heavy metals can slow development; result in birth defects and some are carcinogenic. Industrial waste often contains many toxic compounds that damage the health of aquatic animals and those who eat them.

Some of the toxins in industrial waste may only have a mild effect whereas other can be fatal. They can cause immune suppression, reproductive failure or acute poisoning. Microbial pollutants from sewage often result in infectious diseases that infect aquatic life and terrestrial life through drinking water. Microbial water pollution is a major problem in the developing world, with diseases such as cholera and typhoid fever being the primary cause of infant mortality. Organic matter and nutrients causes an increase in aerobic algae and depletes oxygen from the water column.

This causes the suffocation of fish and other aquatic organisms. Sulfate particles from acid rain can cause harm the health of marine life in the rivers and lakes it contaminates, and can result in mortality. Suspended particles in freshwater reduces the quality of drinking water for humans and the aquatic environment for marine life. Suspended particles can often reduce the amount of sunlight penetrating the water, disrupting the growth of photosynthetic plants and micro-organisms. How can we prevent water pollution If you want to help keep our waters clean, there are many things you can do to help.

You can prevent water pollution of nearby rivers and lakes as well as groundwater and drinking water by following some simple guidelines in your everyday life. Conserve water by turning off the tap when running water is to necessary. This helps prevent water shortages and reduces the amount of contaminated water that needs treatment. Be careful about what you throw down your sink or toilet. Don’t throw paints, oils or other forms of litter down the drain. Use environmentally household products, such as washing powder, household cleaning agents and toiletries. Take great care not to overuse pesticides and fertilizers.

This will prevent runoffs of the material into nearby Water sources. By having more plants in your garden you are preventing fertilizer, pesticides and contaminated water from running off into nearby water sources. Don’t throw litter into rivers, lakes or oceans. Help clean up any litter you see on beaches or in rivers and lakes, make sure it is safe to collect the litter and put it in a nearby dustbin. Noise pollution Noise pollution is excessive, displeasing human, animal or machine-created environmental noise that disrupts the activity or balance of human or animal life.

The word noise comes from the Latin word nauseas, meaning seasickness. The source of most outdoor noise worldwide is mainly construction and transportation systems, including motor vehicle noise, aircraft noise and rail noise Poor urban planning may give rise to noise elution, since side-by-side industrial and residential buildings can result in noise pollution in the residential area. How does it affect us Effects of noise pollution Human health: Noise pollution disturbs our health and behavior in a number of ways including deafness causing lack of sleep, irritability, indigestion, heartburn, high blood pressure, ulcers, and heart disease.

Just one noise explosion from a passing truck drastically alters our endocrines, neurological, and cardiovascular functions in many individuals. If this is prolonged or frequent, the physiological disturbances become chronic and intricate to mental illness. Annoyance: Sometimes, even low levels of noise are irritating and can be frustrating, and high volumes can be annoying. Natural sounds are less irritating than those we find uncontrollable but intermittent sounds such as a tap dripping water can be more irritating than the sound Of falling rain.

Speech interference: Noise more than db can be very difficult to hear and interpret and cause problems such as partial deafness. Sleep interference: Very’ high levels of noise can wake people from their sleep with a jerk and keep them awake or disturb their sleep pattern. This could make them irritable and tired the next day. Decreased work performance: Increased noise levels gives rise to a lack of concentration and accuracy at work, and reduce one’s productivity and performance. Difficult tasks can be impaired, and instructions or warnings difficult to be heard and interpreted, causing accidents.

How to prevent sources of noise pollution Traffic: Don’t live or work near major intersections or roads, shopping centers and sporting facilities. Valleys and falls are noisier than flat roads. Barking dogs: As a dog owner, you should take care to see that your dog doesn’t noon the neighbors with its barking and yowling. Aircraft: Before buying a home, see how far it is from the local airport. Neighbors: Be a good neighbor by not annoying those who live next door with your music or lawn mowing. Solving noise problems: Many noise problems can be prevented by considering others and talking through problems.

Be a good and concerned neighbor by discussing a common problem calmly and in a collaborative spirit to find a common solution. What is global warming Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. What is the greenhouse effect? The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere.

This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows, but it can’t get back out. This is what the roundhouse effect does to the earth. The heat and light can get through the atmosphere, but it can’t get out. As result, the temperature rises. The sun’s heat can get into the car through the windows but is then trapped. This makes what ever the place might be, a greenhouse, a car, a building, or the earth’s atmosphere, hotter.

This diagram shows the heat coming into a car as visible light (light you can see) and infrared light (heat). Once the light is inside the car, it is trapped and the heat builds up, just like it does in the earth’s atmosphere. Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it, the earth would be freezing, or on the other hand it would be burning hot. It would be freezing at night because the sun would be down. We would not get the sun’s heat and light to make the night somewhat warm.

During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it, so people, plants, and animals would be exposed to all the light and heat. Although the greenhouse effect makes the earth able to have people living on it, if there gets to be too many asses, the earth can get unusually warmer, and many plants, animals, and people will die. They would die because there would be less food (plants like corn, wheat, and other vegetables and fruits). This would happen because the plants would not be able to take the heat.

This would cause us to have less food to eat, but it would also limit the food that animals have. With less food, like grass, for the animals that we need to survive (like cows) we would even have less food. Gradually, people, plants, and animals would all die of hunger. What is global warming doing to the environment? Global warming is affecting many parts of the world. Global warming makes the sea rise, and when the sea rises, the water covers many low land islands. This is a big problem for many of the plants, animals, and people on islands.

The water covers the plants and causes some of them to die. When they die, the animals lose a source of food, along with their habitat. Although animals have a better ability to adapt to what happens than plants do, they may die also. When the plants and animals die, people lose two sources of food, plant food and animal food. They may also lose their homes. As a result, they old also have to leave the area or die. This would be called a break in the food chain, or a chain reaction, one thing happening that leads to another and so on.

The oceans are affected by global warming in other ways, as well. Many things that are happening to the ocean are linked to global warming. One thing that is happening is warm water, caused from global warming, is harming and killing algae in the ocean. Algae is a producer that you can see floating on the top of the water. (A producer is something that makes food for other animals through photosynthesis, like grass. ) This floating green algae is food to many consumers in the ocean. (A consumer is something that eats the producers. ) One kind of a consumer is small fish.

There are many others like crabs, some whales, and many other animals. Fewer algae is a problem because there is less food for us and many animals in the sea. Global warming is doing many things to people as well as animals and plants. It is killing algae, but it is also destroying many huge forests. The pollution that causes global warming is linked to acid rain. Acid rain gradually destroys almost everything it touches. Global warming is also causing many more fires hat wipe out whole forests. This happens because global warming can make the earth very hot.

In forests, some plants and trees leaves can be so dry that they catch on fire. What causes Global warming What causes global warming? Many things cause global warming. One thing that causes global warming IS electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and And) are sent into the air when fossil fuels are burned.

Some of these chemicals are called greenhouse gases. We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things. Although this source of energy gives off a lot of pollution, it is used for 38% of the United States’ energy. Some other examples of using energy and polluting the air are: Turning on a light, Watching TV Listening to a stereo Washing or drying clothes Using a hair dryer

Riding in a car Heating a meal in the microwave Using an air conditioner Playing a video game What are people doing to stop global warming? People are doing many things to try to stop global warming. One thing people are doing is carpooling. Carpooling is driving with someone to a place that you are both going to. This minimizes the amount of greenhouse gases put into the air by a car. Another thing that people are doing is being more careful about leaving things turned on like the television, computer, and the lights. A lot of people are taking time away from the television, and instead, hey are spending more time outdoors.
