That's the problem Dcube. We are SO far away from being able to fix it, it DOES seem futile.
It won't get fixed in my lifetime. That would make it easy to say "who cares then?"
I have no kids, so i don't have to worry about how life will be for them.
The same with "global warming". Plus, why should i believe them when they say that 100 years from now the earth's temperature will go up by 3 degrees, when they can't get the "5 day forecast" right?
