Before illustrating environmental awareness, we should first of all explain, what is environment. "Environment" is that which affects the life & development of the organism in its natural habitat. It is the totality of everything that is around us, like biological, social, economical, physical or chemical. All the species influence and are influenced coming under it. Environmental concern is a global momentum in the present context. After completion of world war-II, industrial revolution took place in the European countries for healing of economic wounds caused by devastating war without caring for environmental degradation. So many scientific & technological developments took place to increase production by using natural resources, bypassing the environmental consequences. But when different critical situations arose, world thinkers expressed their concern, UNO arranged various conferences to create consciousness for the protection of the environment. All the environmental situations are arising due to excessive use of nature and natural resources. As a result, climatic change, pollutions, loss of wild habitat, health hazards are growing day by day. Therefore, earth summit in 1992 and Johannesburg convention in 2002 emphasized on sustainable development and finding out solution for controlling environmental degradation
