The term pollution refers to the act of contaminating ones environment by introducing certain hazardous contaminants that disturb the ecosystem and directly or indirectly affect the living organisms of that ecosystem. Pollution in general is the activity of disturbing the natural system and balance of an environment. The increase in the pollution over the years by man has caused severe damage to the earth’s ecosystem. It is responsible for global warming which is leading to the end if all the lives on earth. Over the years there is an extreme increase in the rate of human diseases, and death rate of various animals and plants on earth, and that is all because of the pollution caused by man himself.
There are many types of pollution, but four of them have the most perilous affect on our lives. Following are the four most dangerous types of pollutions and their causes: Air Pollution
Air pollution is perhaps the most common and the most dangerous type of pollution. It involves the direct release of chemicals into the environment. The chemicals then become the part of the air around us that all the living things take in.
The increase in the rate of diseases such as asthma and lung cancer today is due to the increase in the air pollution around us. Air pollution is also a cause of global warming andacid rain. Causes Of Air Pollution
Basically the air pollution is caused by the burning of fuel that directly releases hazardous chemicals into the air. For example the burning of coal releases sulphur dioxide, a poisonous gas which is responsible for acid rain. The sources of such chemicals are the large factories, smoke from the vehicles, chimneys and burning of wood. * Threat To Polar Animals Due To Global Warming
The effects of global warming are playing havoc everywhere - higher temperatures, hurricanes, heavy rains, flooding and droughts have now become more frequent and severe in intensity.
