WHY DO WE NEED TO MANAGE OUR RESOURCES:-
Not just roads and buildings, but all the things we use or consume– food, clothes, books, toys, furniture, tools and vehicles – are obtained from resources on this earth.
The only thing we get from outside is energy which we receive from the Sun. Even this energy is processed by living organisms and various physical and chemical processes on the earth before we make use of it.
We need to use our natural resources carefully Because these are not unlimited and with the human population increasing at a tremendous rate due to improvement in health-care, the demand for all resources is increasing at an exponential rate. The management of natural resources requires a long-term perspective so that these will last for the generations to come and will not merely be exploited to the hilt for short-term gains.
For example, mining causes pollution because of the large amount of slag which is discarded for every tonne of metal extracted. Hence, sustainable natural resource management demands that we plan for the safe disposal of these wastes too.
