W ATER P OLLUTION The 75% of the earth’s surface is covered with water and more that half of the total population of earth’s species resides in water. Moreover, our life greatly depends on water and life without water is impossible. Water pollution not only affects the fish and animals living in the water but also affects the whole food chain by also transferring the contaminants to the consumers depending on these animals.
N OISE P OLLUTION Unlike other the above mentioned types of pollutions does not involve hazardous chemicals or their incorporation into the environment, rather noise pollution is the increase in the rate of noise in the environment. Noise can be extremely dangerous. And it is all around us. It penetrates into human mind and controls it.
S OIL P OLLUTION Soil pollution involves the contamination of soil by the release of harmful substances into the soil. Unlike air pollution, which has a direct affect on human lives, soil pollution causes an indirect damage to humans and other animals.

S OURCES AND M ETHODS BY HUMAN motor vehicle exhaust industrial processes auto manufacturing building demolition fuel production roadway construction
A IR POLLUTION IN INDIA Air pollution is high in Indian cities. Indian cities are polluted by vehicles and industry emissions. Road dust due to vehicles also contributing up to 33% of air pollution In cities like Bangalore, around 50% of children suffer from asthma.
