That is a short-term view. Look how growth will stall and turn into decline if we continue on our present path.

Probably not by themselves, because most people put their own self-interest first, and our economic systems stimulate them that this is the best way.
It needs the concerted effort of many to apply sufficient pressure to take the long-term view and affect real change.
And I guess this is particularly hard, as our current (broken?) systems also promote wealth inequality, and the rich and powerful - those who can help the most - are less inclined to do so, because they'll be among the last to really suffer the consequences of inaction.
