There are many factors that have degraded the quality of the environment like pollution and global warming etc. We should put our effort in all these things, if we want to exit on the earth in the coming future pollution is not a new but still we have not taken any proper steps to bring the level of pollution down as it has reached the optimums level. The main course of pollution on is are plastics, which are used in our daily life and without it we feel very uncomfortable. Plastics is very harmful for human brings and it destroys the environment. In early time there were no plastic bags used only paper bags were used by every shop. In early times milk use to come  in glass bottle but today dairy milk come in a Plastic polythene bags in early times vegetables, clothes they were packed in paper bags but now polythene are used.

　Today there is no one who is not aware of plastic, its harmful effects but then also they prefer using plastic bag than paper bags. Plastic bags are made up of many colour. Plastic bags are also called polythene bags. The professors and engineers have also decided to make cars, ship stick to the drainage system. If plastic is burnt then many harmful gases are released. At least we should stop the use of plastic bags.

　I would also like tell you other course of pollution, i.e. is water pollution. It is very dangerous for environment as many chemicals or oils released from various factories into river, ocean etc., and mies with the water, the fishes take in that polluted water. And after some time they  bell ill and dil. And I would like to share an example of water pollution on march 29, 1989 the oil tanker Exam Valdez left its harbour on the coast of Alasca with 53 million gallons of crude oil bound for California.  Just after midnight, in the early hours of March 24, 1989, it struck the B ligh Reef, a reef off the coast of B Ligh Island in Prince William Sound, Alaska resulting in a leakage of 11 million gallons of oil into the prone William Sound, both the long and short-term effects of the oil spill have been situated comprehensively. Thousands of animals immediately, Between 3 to 5 lakh sea birds were killed and billians of salmon and herring eggs were destroyed.

　In conclusion, I would like to say that love your Earth and Plant more trees and avoid using plastic bags instead of that we used  paper bag.
