Whatever position you have on man made climate change — even if you think it's a Chinese hoax —you'd think that a rational person would agree that we should treat the planet with respect. We shouldn't dump toxic chemicals in the waters, we shouldn't destroy ecosystems beyond repair. We should respect and preserve habitats. It's juvenile to think we can pollute as much as we want without consequence, regardless of your views on climate change.
I think man made climate change is real and the evidence shows it. And I recently did the single biggest thing you can do to stop man made climate change if you care about it: I stopped eating meat. But I know there are many people who care about the environment who just aren't willing to do much about it and who say that the taste of meat is just too good to give up. I was like that for a long time. It's just too hard for many of us to sacrifice something we enjoy and actually do anything for the betterment of our planet.
Consider this analogy. Imagine if I was passionate about preventing rape, but I didn't want to do anything about it. I never spoke out or argued against it. And if a friend of mine told me he thinks it's OK to sexually assault or rape women I never try to convince him that way of thinking is wrong. Instead I do absolutely nothing to change my lifestyle to affect the problem of rape. Would that make any sense? No, it wouldn't. But for those who are passionate about preventing climate change and do not stop eating meat, it makes just as much sense.
As I sometimes say, being against man made climate change while being a meat eater is like being against date rape and being Bill Cosby. Watch the NatGeo documentary Before the Flood on YouTube which goes into the effects eating meat has on the environment. It argues that you should at the very least cut out beef from you diet and switch to chicken, as chicken production's carbon foot print is much smaller than beef's.
