Although I have been prevented by outward circumstances from observing a strictly vegetarian diet, I have long been an adherent to the cause in principle.
Besides agreeing with the aims of vegetarianism for aesthetic and moral reasons, it is my view that a vegetarian manner of living by its purely physical effect on the human temperament would most beneficially influence the atoledo lot of mankind.Albert Einstein
Originally I had the following quote here:
Nothing will benefit human health and increase the chances for survival of life on Earth as much as the evolution to a vegetarian diet
but as Ozh pointed out that quote appears to be a bit too much paraphrasing Einstein. So, I replaced the original quote by the current one.
