Dear Student,
Sustainable development is a pattern of development that promises the use of resources in a way that meet human needs while preserving the environment so that these needs can be met not only in the present, but also for generations to come. It is a need in the present times because the rate of population growth and consumption are rising higher that the the existent resources some of which are non replenishable whereas Natural resource management deals with the management of plants and animals , water, land, soil, with emphasis on how management would affect the quality of life for present and future generations.
