Introduction
We all create pollution therefore everyone can make a difference to reduce pollution. Although it may seem like it is difficult to stop pollution, there are lots of things that can be done every day to reduce or eliminate pollution altogether
What is Pollution?
Every day we pour or release harmful substances such as poisonous , chemicals and garbage into our environment. These harmful substances that end up damaging the environment, are called pollution. Most pollution comes from factories and transportation but as you will see we all contribute to it in many different ways.
All pollution is waste. Waste is unwanted or discarded material and when it is released into the environment it becomes pollution. When most people think of waste they think of garbage or trash that is littered all over the land. This type of waste is the one that most people are familiar with and it is commonly called solid waste. But solid waste pollution is not the only type of pollution out there. Can you think of other types? In addition to solid waste there is air pollution, water pollution, soil pollution and even noise pollution. As you will see, if not handled properly, pollution can and has contaminated our air, water, soil and land.
Air Pollution
Every living creature relies on clean air to survive. Air is made up of a mixture of gases, mainly oxygen and nitrogen, with small amounts of carbon dioxide plus water. Air has no colour or smell, except when it is polluted. Dirty air can affect the health of humans, animals, plants and can even damage buildings. Industry and transportation produce most of the air pollution, releasing millions of tons of harmful substances into the environment each year.
The burning of fossil fuels (coal and oil) is the source of or generates most of the world's energy. Unfortunately it also generates most of the world's air pollution. That is because when we burn the fossil fuels to. produce energy we end up releasing waste in the form of toxic gases Carbon monoxide, carbon dioxide, nitrogen oxides and sulphur dioxides are some of the most dangerous gases produced during the burning of fossil fuels.
Carbon dioxide gases play a big role in the greenhouse effect by trapping heat rather than allowing it to escape into space. It is not just what is released into the air that causes problems; it is also how individual pollutants interact with each other, water and/or sunlight.
Water Pollution
One of the most damaging forms of water pollution is from oil. Oil spills from ships and oil tankers at sea cause devastating water pollution and harm wildlife. These events receive lots of attention on television and from environmental groups, however these spills only represent a small percentage of the total amount of oil that contaminates our water.
Tankers dump oil into oceans as part of their routine cleaning, refineries pump oily wastewater into surface water and oil from city streets are washed into storm drains that eventually enter our. Waterways When people rinse materials down the drain, flush their toilets or do a load of wash, the wastewater usually goes to sewage treatment plants to be purified. These plants will then remove dirt, biodegradable materials such as food waste and a number of other pollutants before the water reaches our waterways. However, most treatment plants can't remove all of the chemicals that are used in products such as paint thinners or phosphates that are used in many detergents and these substances end up passing right through the sewage treatment plant untreated. Other sources of water pollution include the dirt and litter from the streets that are washed into storm drains. In most areas these storm drains empty into underground pipes that will eventually dump directly into our lakes, rivers and oceans.
Land/Soil Pollution
Disposing of acids, pesticides, chemicals, radioactive waste, sewage sludge and other types of hazardous waste on our lands has become one of the most dangerous pollution and waste problem. Most of this hazardous waste is sent to landfill sites or burned in incinerators which in turn create toxic runoff and air pollution. In the past this hazardous waste has also been buried deep underground. However, because of poor storage methods older landfills and underground storage sites may end up leaking hazardous materials into surrounding soils and sometimes groundwater. This results in contaminated lands that pose a threat to people living in the area as well as to wildlife and the environment Not only should we be concerned about the leaking of these wastes but we should also be concerned about the amount of waste that is being disposed of in these landfill sites. Per person, Canadians throw away more garbage than any other country. The more garbage we produce the more resources and space we will need to dispose of it. This is a problem because we are running out of places to locate landfill sites. Nobody wants to live next to a dumpsite but what do we do with all that garbage? We can learn to reduce the amount of garbage that we create.
Even more disturbing is what we are actually throwing out and sending to these dumpsites. There is more paper than any other material found in landfills. Over 38% of all materials a landfill is paper. The next highest is XXXXl, glass and plastics at 34%. Finally, about 15% of the material disposed of in dumps are food and yard waste. All of these materials can and should be kept out of our landfills. If you add up all these numbers, over 87% of what makes up a landfill site could have been recycled, reused or composted. But instead we are polluting our land by throwing them away as garbage and using up our natural resources unnecessarily (i.e. cutting down more trees to make more paper).
Noise Pollution
Modern towns and cities are noisy. Within these cities there is a constant rumble from cars, trucks, buses, machines, alarms and sirens.
Even loud music is a form of noise pollution. Some communities are also located in noisy areas such as airports or near a train track/station. Other people have to work in noisy factories.
When these vehicles, horns, radios, heavy machinery, make loud and continuing sounds they are producing noise pollution. We don't think of noise as being able to hurt us but it does. Noise can cause damage to our hearing and lead to other health problems, especially if you are exposed to loud noises for long periods of time.
Conclusion
At the end, pollution prevention is not difficult. Opportunities can be found at home, when you shop at the store, when you go to school or when you go to work. You can take steps every day to help stop pollution.
Once you get in the habit of thinking about the pollution you are creating, you will soon recognize more and more opportunities for preventing it.
Challenge yourself to find a new way to reduce pollution each week or improve on something you have already started, like riding your bike more often, or walking to school every day instead of once or twice a week.
