Does anyone respect the right of the earth to maintain any specific temperature, amount of underground oil, amount of frozen water, or sea level or is it the problems those cause for humans that ought to be respected.
Ultimately correct.
A world with no polar bears is not no world at all. Nature will continue as it always has, and some other critter will take the polar bears' place.
The issue is whether
we can survive in a world with no polar bears. Can we survive rising seas? Can we survive increasing desertification? Can we survive hotter summers? Can we survive more tornadoes? More hurricanes?
Who loses when humans and the elements go to war?
Love your enemies!
