Now-a-days pollution is biggest problem of whole world not only Nepal. specially, city areas are effected from this problem. we suffering from different harmful disease. our environment is become dirty and it is not easy survive in this types of environment. pollution is creating many problem.This problem is created by man. so, it is our responsiblity to prevent this problem also. To prevent this problem, we should start awareness programme. people should be made aware to reduce the environmental pollution and to make safe from the green house effects. It will help to reduce to adverse environmental effect if people can be informed about these aspects like how the effects of it on animal and vegetation as wellas how the effect of climate change can be reduce. we should give education to the people about pollution and it's effects.

Effects of pollution

Ozone layer is depleted due to the growth of different gases in atmoshphere like sulphure dioxide, carbon dioxide, methane, nitrous oxide, etc. It prevents the harmful ultra voiled rayes coming from the sun. If the ozone layer of atmoshphere gets destroyed, the harmful rayes arrive to the surface of the earth which hinders the life cycle of animals. Because of pollution every living organism of earth is effected. It creates many problem in the life of all living organism. we cannot survive in the polluted environment. polluted air causes air boren disease like-:chiken pox, common cold, etc. we cannot get fresh air to breath. when we use polluted water to drink we may suffer from water boren disease. In polluted water, aquatic organism and aquatic plants also cannot survive. polluted soil also effets the living organism which live in soil. This pollution also effect human beings also. Noise pollutin is also harmful for us. when we live long time in noisey place, it effects our ear. we cannot hear low voice. we have other serious problem also.

causes of pollution


Brick, tile, cement factories,etc.emit pollution like carbon dioxide, sulfur dioxide, dust smoke. pollution degrades the the surrounding physical environment. unnecessary activites of man also degrades our surrounding and our environment. when man use unnecessary things to fulfill their demand and facilites pollution creat. we use different vehicals for thier facilites, the smoke comes from vehicals create pollution and harms our environment. when we use chemical fertilizer and pesticides in field, it mix with the sources of water like-: river, pond, underground sources of water. pollution is created by big industries also. Dirty water of drainage emitted from factries mixed in the sources of water. Becauses of it water get polluted. Big factries only not helps in water pollution, it also helps in air pollution. Because dust,smoke, poisonous and harmful gas is also emitted by industries which helps in air pollution.

Noise pollution

The pollution of sound which is caused by unnecessary activites of man is called noise pollution. This pollutin is seen in urban areas than rular areas. It is the main problem of big cities areas. because in city area more vehicals run. The sound produed by vehicals horn is very noisey. It effets our ear. when we live long time in noisey place, we have problem of not hearing low sound. In city area population is increasing day by day. people of village areas is coming in city area. so, city areas is so crowde. when more people live in city area, they make noise also. In city areas, there is more development of communication and entertainment. people listen music in loud voice. Because of this pollution many health problem is create. we cannot live in pease and alone.

soil pollution

The pollution of soil caused by unnessary activites of man is called soil pollution. This problem is also created by man. specially, farmers are responsible for this pollution because farmers use chemical fertilizer and pestisides in field to grow more cropes. At first, more cropes is grown but after sometimes it shows negative effects. It destroy the useful organism which helps to maintain the fertility of soil. unnecessary use of chemicals fertilizer and pestisides decrease the fertility rate of soil. when we eat the food which is grown by using chemical harms our health our health. we suffer from different types of disease. when we eat harmful food it harms our internal body and it may damage our body parts.

air pollution


The pollution of air causes by unnecessary acivites of man is called air pollution. It is caused by harmful smoke comes from industries, old vehicals,etc. The harmful smoke like carbondioxide, sulphure dioxide mix with air .It causes air borne disease. Like common cold, chicken pox, etc. It also causes ozone layer depletionand green house effect.When we breath in polluted air we should suffer from different disease.Through this polluted air different types of disease is spreading.Different types of unknown disease is coming from our neibour country. we should stop this kind of pollution. we should start awerness programme. we should give education to nnpeople.
