Editor, Times of India,Kolkata.                               Sub : Editorial letter on environmental pollution. Dear Sir,            Environmental pollution is at its peak level in our country. PARTICULARLY our CITIES are not healthy.           Air pollution is CAUSED by reckless cutting of trees, chimneys of factories, emissions from vehicles, burning            of coal, wood and fossil fuel.                           Soil and water pollution is caused by factory exhausts, excessive use of insecticides etc.          Noise pollution occurred by loudspeakers, high volumes of TV sets, horns etc.          Pollution of these kinds is dangerous for mankind. . Thanking you,                                                                                                                                                         Your's faithfully                                                                                                                                                                                         Abhi Sen
