Absolutely, I'm not really a moralist, eating meat was how we survived in harsh climates and environments as we header out of where our primary food source was not available. There are times and places which this choice would be necessary unfortunately, like those people on Flight 571 that crashed in the Andes, they needed to eat their fellow humans in order to survive and I would of done the same.

Also, this is probably why there has been a backlash against general vegetarianism by some people who've lived in say places like Norway where they've eaten meat for thousands of years and it seems "natural", which it perhaps is in that sort of environment. A huge chunk of the developed world lives in places which are not suitable for human habitat outside of relying on industrialization and advanced technology. Most people aren't willing to accept that our ideal human environment is the tropics and food grown there.
