Sustainable development means that the development at present should not come at a cost of depletion of other resources and should not hamper the needs of the future generation of society. Development should be done without damaging the environment. Sustainable development and future needs go hand in hand. If natural resources are not reserved, then development will be constant or may even decline after attaining a certain stage. Exploiting resources unethically will ultimately undo the development that a country may have achieved. Hence in the future those resources will not be available for further progress.
Sustainable development is important because it saves national budget, fulfils the needs of the people, conserves natural resources, helps in the coordination between the natural resources and people and conserves natural resources for future generation.
