The modern man may be proud of the progress he is making in every sphere of life. the fresh air and pure water we used to get is polluted now.this is all because of negligence and carelessness.the increasing number of factories is the one source which is causing all the 3 pollution.the waste water products of these factories go into the canals and rivers through pipelines,thus making water toxic and unfit for use.smoke from the chimneys makes the air full of dangerous gases,and noise from the machines and sirens create sound pollution. increasing in vehicles is also one of the reason for both sound and air pollution.another main thing is deforestation.
a movement should be taken on a large scale to control this pollution and save mankind.and also we must grow more trees,water should be boiled before use ,factories and heavy vehicles should not be allowed in residential area to prevent air water and sound pollution to some extent. ,
