The science of sustainability is parallel to the Newton's third law of motion.
It says that every action has its equal and opposite reaction.
If human activities keep on destroying biophysical resources then it will boomerang as climate change, greenhouse effect and global warming.
If man mends its way and puts his heart in repairing the ecosystem and share the good and services equitably and appropriately, the environment shall sustain until eternity.
The need of the hour is a healthy environment management.
The primary concern shall be demand management.
