Me too. Al isn't going to debate anyone on this his pet project.

But there are some very important finds that (no matter the cause human or nature) do need our attention. We have a lot of Science on both sides yet that doesn't change the facts on the ground.
Mankind can for the first time do something to change the situation in our young history. We are the first of many species, that have gone by the way, that can have an impact on the outcome of our surivival. In earths 4.5+ billions of years history we can decide our fate to some degree, if we focus and work together as a unified world people.

And if we do that together the costs won't be out of reach. Or we can debate it till one side is proven wrong and the other is the winner.
