You can quibble over the precise details of the mechanisms involved, but the basic theory has stood up very well. No doubt it will continue to be refined as we learn more about biology.

I'm not sure how a 20-year-old quote by Carl Sagan can be counted as a score for the science team
Whatever you may think of the man (and after reading some of the quotes he's written, having never heard of him before, he sounds to me like he has got his head screwed on the right way), the quote itself is solid.

People say we are destroying the world, that is a pretty egotistical thing to say. The world has been here for billions of years and will be here billions of years from now. Eventually either the sun will explode or the Earth will repair itself. Either way, man will be gone long before then, so we're not destroying the world, the world is destroying us.
"Destroying the world" is hyperbole, and you're a fool if you don't realise that. For sure, the Earth itself will be around for a long, long time - heck, it's had multiple asteroid impacts and it's still going. The question is, how long will we be on it? If you believe widespread scientific opinion, we're slowly but surely digging our own graves.
The Earth itself, of course, does not care. This big ol' lump of rock will keep orbiting the sun for a long time yet, no matter what we do. It's also very likely that some form of life will persist. "Some form of life" just doesn't necessarily mean "humans".
Re: Recycling
I know you're an intelligent person, Deadron, so whenever you state a position different from my own I'm forced to stop and think about it (whether I decide to agree with it is a different matter, of course!) So I went back and read your old "Recycling is Evil" blog post, and I have to say I don't agree. Mind if I take this discussion there?
Which ones? It seems to me that no theory has been poked and prodded in more directions by scientists than evolution.
And niggling details here and there aside (is "punctuated equilibrium" a part of the system, etc), the overwhelming fact of evolution comes down to this:
It has answered a vast number of questions, and has pointed to answers time and time again. Nothing in biology makes sense without evolution. Evolution has contributed greatly to our understanding of the world. You can argue over details, but the system itself is simply overwhelmingly proven. DNA has turned out to be a mechanism exactly in line with evolution, and DNA has led us to further discoveries that confirm evolutionary theories.
When thinking about something like creationism, just ask yourself: "What has this contributed to our understanding of the world in the thousands of years it has been around? What do we know today that we wouldn't have found without creationism as a basis?"
On the one hand we have a theory that has had a profound impact on our understanding of the world; on the other we have a myth that has contributed nothing. The perpetrators of the myth deserve no particular consideration or credit in scientific terms.
