The North, to cleanse their own environment has fact fully, managed to move dirty factories of South. When the West developed, it did so perhaps in ignorance of the environmental impact of its activities. Evidently such a path is neither practicable nor desirable, even if developing world follows that.
3. Need to Save Humanity from Extinction -
It is upon us to save the humanity from extinction. Consequent to our activities polluting the environment and depleting the biosphere, in the name of development.
