In the recent years, environmentalists are insisting upon “sustainable management of natural resources” due to a number of reasons:

•Most of the natural resources are limited. These resources will get exhausted in the near future and will not be available for the future generations.

•They require hundreds of years to get replenished and human population is increasing at an enormous rate. The available resources will not be enough.

•Due to over-exploitation of these resources, our environment is adversely affected. We must reduce the damaged caused due to utilisation of resources.

•A lot of waste is generated from using the resources which is not properly disposed. It adds up to the pollution.
