I don't consider my self very religious because I have no religion I subscribe to. But I do believe in God. I agree with this scientist 100%; not because of my belief in God, but because without a cleanup mechanism that we don't understand yet, our existence on this planet would have ended long ago.<quoted text>
This is about as tough a question as there is. But I'm going to give you a straight answer. It's not that this fellow is religious, but that his religion trumps his science.(And he is a serious scientist, too.) Because of his religious beliefs, he assumes our world must be self-correcting. A real scientist must confront the horrible truth that we could screw it up.
I think most folks would accept that if we got into a sustained nuclear war, we could trash this planet. But if you subscribe to the idea that God can fix anything we throw at this pebble, why sweat it?
I do think that this planet is resilient, and can bounce back from very serious insults. However, that recovery may not include fragile humanity.
Remember that our earth is encapsulated and nothing leaves the planet unless we fly it into outer space and release it. All the water on this earth is the exact same amount of water that was here ten thousand years ago. It may have taken different shapes such as ice or vapor, but it's the same amount of water. Same holds true of all the pollution created by fires and volcano eruptions. It doesn't leave and pollute the moon. It stays here and yet by some magical process, it gets cleaned up.
If we set off every nuke on earth, all we could do is kill every living thing on it, but we cannot destroy the planet. It's just not possible. And in a few hundred years or so and God's will, some sort of life would start all over again.
But whatever reason this scientist believes the earth can take care of itself, it doesn't discount the fact that thus far, nobody has challenged his findings of these computer models that I know of.
