Looks like Mr Smith from the Matrix is correct, humans are a virus slowly choking the world to death.
If humanity started recycling every piece of recycleable product today, addressed the wasteful use of fossil fuels. Placed a moratorium (sp?) on industrial fishing for 10 years. And a raft of other badly needed, but highly controversial eco-friendly legislation. Perhaps we might just stop the planets ecosystem being driven into meltdown.
Yeah, that will happen in todays consume and dispose society.
