Thats top-notch science there, tboy
But it is a simple example of what we're doing to the planet.
As for your trees cleaning the air: what if we've cut down all the trees? What cleans the air then? (and before you say another word, we HAVE cut down just about 90% of the trees in southern ontario so don't even go there).
Ok, here's another simple experiment:
You have 1 cleaner in a 10 x 10 room. You have 5 guys bringing in buckets of dirt. How long before the room is full? This is a perfect example of the "load" we're expecting the plant life to clean. We've reduced the amount of "cleaners" yet increased (exponentially) the amount of pollutants.
I think the problem is people see the world as an infinite resource, but it isn't. It is finite. There is only so much we can do before the system breaks down. I mean seriously, we TRUCK our garbage to another country because we've run out of room here, doesn't that tell you something?
I just thought of a good example of the human race's ignorance:
The buffalo. Back in the day when they/we moved west we saw great herds of buffalo. Millions of them. So mankind went out and said "hey look at all dem dare buffalo, we can shoot as many as we want, lookit dem all"
A few years later the same people said "hey wait, where all dem buffalo"???
