Human evolved as omnivores over thousands of years. Yet since the invention of farming there is no longer a need for us to be omnivores. Even if we wished to we could no longer collect, hunt and eat our food in the same way as our ancestors as we could not support the human population. We have outstripped the pace of our evolution and if we do not want to be turning ever more land over to farming we have get our food from the most efficient sources, which means being vegetarian.
