The end as we know it.

I happened across this interview through facebook on how we have harmed the earth and have passed the tipping point of survivals of our species. "Eaarth": Earth is over is a powerful interview of Bill McKibben, the author of "The End of Nature," on how we have far surpassed what is sustainable. What I cannot believe is that, "Forty-four percent of Americans still don’t believe global warming is man-made." This is very scary. We have hard evidence, but American are ignorant. Little changes by individuals, might make you feel good, but WILL NOT make a difference. We need governments and major corporation make changes on what they do.
