      Keep believing in this crap. If god was real why can't any of the tales in the bible be proven real?

    Interesting stats, but one question: what does being a vegetarian have to do with Earth Day? If this is about supporting agriculture and methane emissions, I'm sorry to say dudes, humans are omnivores. You can't change that fact; we biologically need protein and are built to consume meat as part of our diet.

      Epic Fail. Raising animals for meat uses far more resources (water/food/land) than does just eating plant materials. Being a vegetarian/vegan is one of the most earth friendly things you can do. Sorry to say dude but being an omnivore does not mean we need to eat meat. We can if we want but I've survived with out it for 20 years. I look and feel ten years younger than I am. My cholesterol and blood pressure are fantastically low. And one last thing.....If people used their natural abilities to evolve beyond treating other animals as a resource and acted with compassion we might find we treat each other better as well.

      While I'm not vegetarian myself, people who are have a much smaller impact on the environment. This is mostly due to the amount of energy put into growing feed for livestock and the huge amounts of fertilizer needed to grow corn (more corn is grown for cattle than for humans in the US). Add to that the significant amounts of manure produced by livestock and you have a very significant environmental impact.

      And as far as omnivores go, most omnivores in nature (see: Bears) have a diet that is chiefly vegetarian which can be supplemented by meat.

    With the way the hens were going at it here last night, doubt we'll be seeing many eggs being layed here this morning. Plus roosters confused as hens don't lay eggs. They tell jokes. 🙂

    @tomas. I believe it says that God stays in heaven and he sends his son again. Remember? What happened last time his son was sent?

    God himself? The earth barely rates as his footstool, and only then on his word; "The heavens are my throne [says God], and the earth is my footstool. Where, then, is the house that you people can build for me, and where, then, is the place as a resting place for me?"..."To THIS one, then, I shall look, to the one afflicted...and trembling at my word."
    "The one slaughtering the bull is as one striking down a man. The one sacrificing sheep is as one breaking the back of a dog. The one offering a gift – the blood of a pig. The one presenting a memorial of frankincence is as one saying a blessing with uncanny words. They are also the ones who have CHOSEN their own ways, and in their disgusting things...have taken delight. I [God] myself, in turn, shall choose ways of ill-treating them, and the things frightful to them I shall bring upon them; (cont)

    ...for the reason that [God] called, but there was no one answering; [God] spoke, but there were none that listened; and they kept on doing what was bad in [God's] eyes, and the thing in which [God] took no delight they CHOSE." -God, as quoted by Isaiah 66:1-4 (to those who chose to love God, his first-born son Jesus, his good angels, and his children, (not to mention loving your enemies) pls. continue reading through v. 5. ty)

    It takes about 6-8 times as much water to process red meat as it does poultry. If you really want to conserve water, eat more poultry and seafood, less red meat.

    @Luca B. I'll vouch for that. (bears being vegetarians) They are. They even eat slugs and worms and bugs. Carnivor? You betcha. Especially when there are cubs to feed. But like T-Rex, a scavenger/opportunistic hunter misclassified as an apex predator, so-too has the image of a bear been altered in the eyes of men. 'Specially 'men' under the influence of mind-altering pharmaceuticals who have but little choice to adopt as their own the imagees and sounds they just recieved from their *boob tubes*. (why we called them boob tubes to begin with)
