What are the indications for the future of humankind?

The ecological balance of the earth has been continuously receiving big setbacks since the evolution of human civilization. With the ever increasing population, the need for natural resources is automatically on a rise. Due to this, climate change is fast setting in. Unchecked burning of fossil fuel has created a blanket of carbon dioxide around the world. Along with this, the melting of glaciers and the subsequent rise in global warming  may lead to a catastrophe in the near future. The changes in the earth’s environment give indications that we need to change our ways of life before it is too late.
