I'll say that despite whatever lies both sides in this debate might spout, there's no denying it.
We DO have a problem, and we really do need to do something NOW. I have a strange feeling that in maybe 20-30 years, it might have worsened to the point of being too late for us to do something. Though it could be a longer time.
But let's remember that old proverb here.
We do not own the Earth, we simply borrow it from our children!
