Wow, that's a bit aggressive for a mutually supportive sub. I'm quite within my rights to complain if I'm sick of hearing about something, look at it like this; People know full well that smoking will kill them, yet they still smoke.
Surely, that is the same for most things. People know we are killing the planet, yet it won't effect them directly, so they don't care. Shoving it down their throats won't change that, it doesn't with smoking, just take a look at a packet of cigarettes. It's the whole short term effect/ long term effect.
You say it effects everybody, can you tell me how climate change will effect me? The only effect I've noticed is my straw at mcdonalds is paper and gets soggy. I'll be pushing up daisy's before it effects me in any way I imagine.
Personally, I agree that change needs to happen and I have (within the last year) started making what changes I can to limit my effect on the planet. Perhaps you should calm down a little bit, and stop taking pops at strangers over the Internet? Just my two pence.
