Essay on pollution:Environmental pollution is the biggest menace to the human race on this planer today and this article is an essay on pollution describing its effects on human beings and whole environment. Basically pollution means addition of impurities to the environment which consists of earth‚ water‚ air‚ plants and animals. If we kept on polluting them then for sure the existence of human and nature will be hampered.Firstly there is a growing amount of atmospheric degradation which causes

Describe the implications for life if a body of water is affected by thermal pollution. Thermal pollution is a temperature change in natural bodies of water of that can and often does have negative impacts on the nearby ecosystem caused by human influence. The temperature change can be upwards or downwards. The major sources of thermal pollution are power plants and industrial factories. In most power plants‚ heat is produced when coal‚ oil‚ or natural gas is burned or nuclear fuels undergo fission
