Conservation

The biosphere extends from the oceanic deeps to luxuriant rain forests. Human beings play a vital role in maintaining the flow of energy in the biosphere. At the same time, human activities cause significant damage to biodiversity.

With an ever-growing population and demands, there is more pressure on biological resources such as forests, water resources, etc. This pressure causes serious damages such as alteration or loss of habitat, species extinction etc. It harms flora and fauna on earth. There are places on earth that are both biologically rich and deeply threatened. Human-caused changes are beckoning imminent danger in the near times, which is evident from reports from various climate change-related organisations around the world. Hence, it is man’s duty to conserve and care for the earth and make it a better place to live in.
