Please, be kind to our planet. It is a shared and restircted resource. Shared means that ignorance of some people does affect other people. Restricted means that the effect of such an ignorance is dangerous. It's not a threat of death, it's the threat of extinction.
Global warming is not a dog — if you survive facing it for a day, it does not mean it won't harm you later.
No matter how late, today is still sooner than tomorrow, so please try to find ways to become more modest: take a bike instead of a car [1,2,3,4,5], Reuse-Reduce-Recycle, do not waste energy, water or other things. It will payoff sooner than you may belive :).
