World has been industrializing rapidly as it did in the past as well. We humans realized its consequences pretty late. Environmental change is the biggest threat to the world collectively because of the excessive exploitation. Careless usage of natural resources now took us to the brink of destruction. In the past few decades, we have lost nearly a million species. This for me is the biggest ever loss we have had because we cannot reverse it ever. Along with specie lost, the overall average temperatures have already risen by more than 1.5 degree centigrade. Now we face frequent droughts and the soil fertility has been lost in many parts of the world.
