I like to watch "Planet Earth" on BBC America. Just heard that in the last 50 years, we've cleared almost 50% of the rain forests in the world.
I think this fact, coupled with the population growth, is more damaging to our environment. Trees use CO2 to make oxygen... I think removing our means to lower the CO2 levels as fast as we are is hurting us more than the emissions.
Volcanoes have erupted in the past and put more CO2 in the air than we ever have... yet when we had plenty of trees to use it, we went on 'bidness as usual', eventually.
As I said, our emissions are not helping, but I think cutting down all the trees may be hurting us even more. Put them together... and here we are.
