If you were to set aside all moral, or ethical issues or "feelings" dealing with the consumption of animal "meat", you should, daily struggle with the "waste" factor, I know I do.
More protien can be produced via plants, in most cases significantly more, with far less pollution than can be produced with any animal including the really "clean" ones like fish and chicken.
Basic biology told us all that....
Sun give to plant. (producers/autotrophs)
Plant give to animal. (primary consumer)
Predators take from animal. (secondary consumer)
Since we can't turn "sunlight" into energy it makes sense to get as close as possible. That would mean being vegetarian or be constant members of the "primary consumer" group.
The step between "primary consumer" and "secondary consumer" for protein and energy accounts for a huge loss. The loss is not just in bio energy "ATP", but also in energy of production including land development/maintanence, fertilizer, hydration, "man" hours, etc.
Being vegetarian would drastically reduce humanities "footprint", as well as push the evolutionary envelope for great growth and change.
That being said, I still eat meat. I've given up smoking years ago, I barely drink, I've been married for 6 years, same woman for over 8, so I gave up "whoring". I am in great shape, I partially gave up tv/games to do it and maintain it. I can't seem to give up the meat, it is almost like a damn addiction. I have drastically cut back. I only eat it a couple times a week, but I still do. I hope that perhaps our offspring can.
The question is, can you set aside all the stigma that comes with the idea of vegetarianism? Can you see the benefit to it?
A typical vice of American politics is the avoidance of saying anything real on real issues.
