So you're a nihilist. Why even bother to participate in the thread?
As for species, extinction happens whenever one species overruns others. Mass extinctions have happened many times in the past. I am sure we are contributing to extinction with our unfettered growth, but it will happen eventually anyway.

I prefer the term realist.
I don't think man-made mass extinction is ever going to stop. Man is spreading like a virus across the planet and to think that you are going to get 7-8+ billion people to stop is just crazy. My point is that there have been multiple mass extinctions, some drastic, and some gradual. It has happened before and it will happen again.
The way to do it is with laws (and force). It isn't like we have to get everyone in the planet on board.

Are we having an affect on the planet? Of course we are, it is just my opinion that we are having less of an affect on the temperature that some people want us to believe. There are larger forces at work on this planet than man.
to the poster saying Earth atmosphere is a closed environment, wrong. The interface between Earth atmosphere and the rest of the universe is an active zone with stuff blowing out and falling in. Vulcanism. bioeffects. Water soluble chemical effects. Fires. And who knows? Maybe mankind can get off our collective asses and make that interface even more active.
p.s. Trees don't produce ozone.
The ps. was not directed to you, but towards another poster. My apologies.
Matter at the top of the atmosphere is constantly being blown away by solar wind and energetic radiation - tons infall, tons outgas daily. Solar radiation also causes changes to the atmosphere, such as the creation of C14 and ozone.
There are a multitude of geological, biological and chemical mechanisms in the land-air-water interfaces that incessantly act. The earth's atmosphere is in constant flux, the miracle is the long term homeostasis of the entire planetary system.
