Do you think the use of resources should be sustainable? Why?

The use of resources should be sustainable because many non-renewable resources can get exhausted if they are overexploited. Over-exploitation of resources would result in depletion of various fossil fuels, metals etc. This will hamper the economic development of the nations. Sustainability of resources means that resources should be utilized in such a way that requirements of not only the present generation but also the future generations are met.
