Sustainable development means that human society must meet their expectations and live without compromising the needs of future generations to meet their needs.
For example, use of non-conventional resources (wind, solar, bio mass energies) in place of conventional resources (coal, fossil fuel, oil etc).
All these non renewable resources or non conventional resources create pollution which lead to global warming and imbalance in the nature. Due to this imbalance, the nature revert and all these leads to floods, tsunami, landscape etc.
There is great need to save all the conventional resources for the future genaration as the are limited in number and should start using non conventional resources.
