HAHAHA! I'm going to steal this.
If all humans suddenly became sea algae instead, we would save an amazing amount of fossil fuels and drastically decrease green house gas.
Seriously, just let people be normal people damn it. I eat my beef and drive my gas wasting sports car. Vegans, U MAD? Clean the french fries out of your vaginas.
Research has undeniably proved that fish oil has undeniable health benefits, creatine in meats is useful for cognitive and muscular performance, and that protein from animal sources are greatly superior for absorption. I dislike wasting resources and use whatever I have with a purpose. Vegans are just being stingy and giving up some of the best things in life...is an incomplete life worth living? I suppose the average people who doesn't have a clue what he's doing or have ambitious goals should become vegan, but to become the best, you should not live on the bare minimums.
If by vegetarian, you mean that you take a fish oil supplement, and get in plenty of milk and egg proteins, I would hardly call that vegetarian. Animal protein sources are animal protein sources, don't delusion yourself into thinking that they are vegetables.
Vegan is an acceptable lifestyle choice, just not for those who seek to be badass and bang fine ass bitches. If you are one of these weirdos who supplement with a lot of plant protein powders, you actually crave burgers, steaks, bacon, and eggs, but are in denial.
