Air pollution is caused by the injurious smoke emitted by cars, buses, trucks, trains, and factories. Even smoke from burning leaves and cigarettes are harmful to the environment causing a lot of damage to man and the atmosphere. Evidence of increasing air pollution is seen in lung cancer. Water pollution caused by industrial waste products released into lakes, rivers, and other water bodies, has made marine life no longer hospitable. Humans pollute water with large scale disposal of garbage and other household waste. In many "rural areas", one can still find people bathing and cooking in the same water, making it incredibly filthy. Noise pollution, soil pollution and light pollution are also damaging the environment at an alarming rate. Noise pollution includes aircraft noise, noise of cars, buses, trucks, vehicle horns, loud speakers, and industry noise which are extremely harmful to the environment. 25.
