Hello there, I'm from South Africa.
I agree with you, we are technicaly killing ourselves and other species, but some people DON'T know how to reduce the amount of global warming. I've just posted my out post suggesting ideas, and how we can reduce "Air Pollution" so you can't really just say "Stop global warming!" But you must remember, WE must remember that we can't just stop global warming all together, but we can try to reduce it. For example: car pooling, and for the people who smoke to try to stop smoking.
But yes I do agree we should put some effort into stopping global warming.
