Human needs are unlimited while the resources are limited. The use of resources has increased tremendously during the last 100 years due to extremely large amount of development in science and technology and population explosion. There is a haphazard and irrational use as well as waste of resources that too on a very large scale. If we keep on exploiting the resources this way then soon they will exhaust and we will not be able to maintain the development and the current life style.
Moreover, the economic development of a country depends on the richness, development and management of its resources. Due to excessive use of resources, the problem of waste and pollution arises. Wildlife and vegetation also gets disturbed largely. Thus, in order to reduce wastage, it is very important to keep the environment clean and secure our future resources.
