The current global warming hype is just one Politicized theory, the same as the global cooling theory that dominated and was politicized during the 1970's. Kyoto protocol is there to enable some people to make some more money by buying and selling "CO2 quota". 3rd world countries will be able to sell the quota, and industrialized countries will buy the quota.
If you're really concerned about the environment, direct pollution to the water system and the air (in the form of toxic gasses, not CO2) should be controlled and hopefully stopped, because that's what causes real (and not hypothetical) damage to huge ecosystems.
