Why is sustainable management of natural resources necessary? Why is reuse better as compared to recycle?

We must use the natural resources in a sustainable manner to conserve the biodiversity and reduce their over-exploitation. Over consumption of these resources will greatly affect the lives of our future generation. The rapid rate of consumption will exhaust most of the available resources. These resources need plenty of time to get replenished. Moreover, significant reduction of one resource will affect other resources also.

Re-use is a better strategy as compared to recycle. Recycling materials require energy as well as money. Re-using is simply using the same original item again and again without wasting money and energy. Recycling also causes air and water pollution to some extent. Most importantly, recycling requires wastes to be segregated.
