human life is very important. They are essential and have adverse impacts on
the environment,which has a direct relation with all living things. The three
essentials for any life Air , Water and Food which constitutes our environment,
are being polluted / adulterated. Our environment is having majority of
chemical substances due to various humans activities. It is not the case of
today but of the past as well. The difference only lies in the ratio of
population verses environment, which is increasing day by day. As a result,
there is a direct impact on the physical and chemical environment. These
chemicals are the waste from industrial and agricultural processes, structural
materials, pesticides, insecticides,weedicides etc.It is evident that some
chemicals are useful but many are toxic and harm the environment and our

chain of interconnecting ecosystems. Use of safe and useful chemicals not only
minimizes the risks occurring in the environment but also in human beings. -
