To put it another way, if we can't restore balance here how can we hope to create and maintain balance in an extremely hostile environment? There are various ideas for "terraforming" the Earth, e.g. by seeding algae. Not to mention the potential impact of many boring conservation options, like smaller engines, smaller vehicles, and a punitive gas tax (I'm sure this will be popular). |
It would be quite easy to restore balance here. It basically all boils down to the amount of CO2 and other greenhouse gasses we keep putting into the atmosphere. Greenhouse gasses are needed (without them, we wouldn't be here), but I like to think the earth can do a good job of keeping the levels where they need to be.
As long as stubborn politicians and rich corporations run the world, we won't have much luck with anything.
