I am sure we have not helped thats for sure... look at the rain forest clearing alone.

...but having said that..
I do not believe mankind has the power to turn this planet into a blackened shell with no life whatever....
we are just not that powerful....
can we stop the wind? no we cant..
can we produce rainfall ?no we cant
can we turn the tides? no we cant
we havent the POWER.......
can we do harm? you betch ya.
can we do better.? I sure as hell hope so..
will it stop CLIMATE CHANGE whatever we do?
nope I am pretty sure it wont....WHY... because we dont have that sort of POWER
man is not meant to have that power.....
this planet has been through amazing climate changes over its 300 hundred million years of life give or take...
and its survived.... lets stop the PANIC....just clean up our act...never let our rivers run dry again....little things like that!...
