Nobody suggested you eat berries and go naked. cutting out meat and if you are willing, dairy and eggs, is about the biggest thing you can do for the planet. A pound of beef takes 5214 gallons of water to produce, chicken 512 gallons, a pound of wheat takes 25. Cattle consume 16 times as much grain as they product in meat. 2.5 acres of land can support 1 person on beef or 15 on wheat or 19 on rice, 22 on potatoes. The world could support 10 billion on a vegetarian diet (even more on a vegan one), currently the population will not be sustainable long term. This is not just crazies like PETA reporting this information, even the UN is saying these things. But we're too fucking selfish. As long as we have our triple bypass hamburgers on our plate, fuck the climate refugees in Bangladesh. They are just poor brown people anyway, we're not willing to "sacrifice" any part of our cushy western life.
