"In any case, if we subscribe to the insepidly stupid lack of logic that it's "murder" to kill one animal to consume it's meat, then veganism, which requires the killing of THOUSANDS for one crop of animal ranging from insects to birds to rodents to game animals through poisons, shootings, traps, machinery (when all they wanted to do was to keep eat those vegetables), ETC ETC ETC must be considered akin to genocide."
I think what you meant to say was that vegans are responsible for killing off crops that animals would be dependent upon? If that is the case, it is far from the truth. When you gain a fruit or vegetable from a plant, you do not actually kill it. The plant can produce many fruits and vegetables within a lifetime without being harmed. In fact, the plant is dependent on animals to distribute seeds to, in turn, grow more of its kind.
Carnivores were meant to keep herbivores in check; however, with the population rise of omnivorous species, like humans, it is actually worse for the environment and it is not just about morals. We have led to the extinction of many other carnivores as we have taken over. Additionally, more animals means more crops need to be planted and thus, they end up being genetically modified, which makes their quality a lot worse than the real thing. The amount of waste and pollution caused by domesticating animals for food means more pollution is released into the air. The plants that maintained the balance of what we need to live may actually find it hard to keep this balance and sooner or later, it will lead to the omnivore and carnivore demise.
Remember, you can be an omnivore/carnivore; however, the further you are up in the food chain and what your diet entails, also tells of how long you will live. With a few exceptions, herbivores outlive carnivores and omnivores. Structurally, there is less energy acquired from eating meat than eating a fruit/vegetable diet.
If our body was an engine, you would be getting more energy per fruit/vegetable than meat. It's kind of like unleaded gas with crap vs. unleaded gas with detergent.
