Wild animals are removed from the forests for human inhabitation.Killing of wild animals is a hobby for some people. By killing these wild animals man is exploiting his own natural wealth. This killing of wild animal is an important environmental issue.

     plastic is one of the modern ingradient used by humanity. Many substances used by man in their day to day life is made of plastic. After its use these wastages are thrown somewhere else. For eg: rivers, ponds, lakes, freelands are used for their residence . These residing plastic wastes may causes pollution to water, soil, air etc. When these plastic wastes are burned it affects the air and thus produce air pollution. Plastic wastes also reduces the soil fertility of lands. When these plastic wastes are disposed to rivers, ponds etc it may affect the aquatic environment. Metallic and plastic pipes may also contribute cadmium in water.

d) indiscriminate use of fertilizers and pesticides

       The fertilizers such as various nitrates used for the crops are washed to ponds and rivers. These fertilizers contaminated drinking water. On reduction of these nitrates to nitrites in the stomach, it combines with haemogobin and reduces the oxygen carrying capacity of blood. The fertilizers used for agriculture in large quantity reduces the soil fertility. Indiscriminate use of fertilizers may cause various health disorders.
