The word “environment” means “the natural conditions in which we live , such as air , water and land” .We have inherited this environment from our ancestors. We have a duty to preserve it and hand it over to the next generation. But what is happening today? We are polluting the environment and making the earth unfit for human habitation. Why do we do it ? We do it so that we can enjoy pleasures for a while. We are destroying future generations for the sake of satisfying our desire for pleasures. Future generations will curse us for our misdeeds. We should realise our mistakes and take steps to protect the environment and to prevent pollution.
