Indy:
So, you side with Castro on that one?
Regarding the food chain, BTW, our habits and selection of food have a lot to do with how much land is needed to feed each person. Eating corn directly is for instance many times more effective than feeding the corn to pigs and eating the bacon.
As forr PPM, I'm not getting you. CO2's PPM's are measured all around the globe, and are simply showing increases. We are not breaking the world record yet, but we're sure heading there.
And Lazs....what do I want to do?
"What do you want to do? How much are you willing to suffer to feel good about it.. like you are "doing something"... or.... more accurately... how much are you willing to make everyone else suffer?"
Maybe stop buing their tobacco (then they can use their land to feed themselves) and stop paying them with artillery and ammo?

Honestly, we fat westerners are a good source for the 3rd world pillage, since we benefit from their quick and illgotten gains. It gives us cheaper colonial products while it lasts. In many cases our western productions cannot compete with their prices, since we have a different setup for ourselves.
Of course this will eventually have an end. Might be a rather naughty one.
Then on to vapour. Yes, Water vapour is indeed the greatest of the greenhouse gases, and I think it was actually me who pointed that out in the first place. Here we enter the borders of the doomsday theory, for heating will also increase the quantity of water vapour, and with heating enough we will enter the vicious circle leading to Venus atmosphere. (I rather don't favour this one).
And Jackal, this is the funniest .... ever....
"The caps melting is proof of nothing in relation to global warming. Ice has been known to melt before."
So, the ice suddenly starts melting at an increased rate without it having anything to do with warming? Looks like you have to go back to physics, - 1st grade
