Botnst and KirtVining are on the $$.. I'm a recent bio grad, and having taken a year of enviornmental science/issues (mainly in an effort to become informed..) the Huge amounts of CO2 being released are far more then our planet can handle. True, the excess amounts of CO2 does provide more 'food' for plants, but before they can use all of this CO2, there will be other limiting factors.. never mind the gross rate of deforestaion taking place on our planet. Another concern is the amount of CO2 being absorbed by oceans, at present they are absorbing huge amounts of CO2 which in large part has helped keep our atmosphere from getting completely overloaded. There will come a point, when they are saturated and we will see skyrocketing levels of CO2 in our atmosphere. No one is really sure when this will be reached as our knowledge base is to limited, but it is a very real threat.
This whole notion of Humans can do it better has been proven wrong time and time again.. I have no doubts this will eventually bite us in the ass as well:-/
