You should read "The Vegetarian Myth". It's nothing we don't know about from a nutritional view but the author explores the ethical aspect as well, being an ex-vegan. Growing crops required the deaths of countless animals and in fact, the loss of whole ecosystems. Harvesting 1 humanely raised cow, involves less death than growing the same calories in plants.
The bottom line is that death is required for life to exist and accepting that is what it means to be an adult.
Thanks Stuward. Just added it to my 'wishlist' on Amazon. Sounds very interesting - Just shows you really don't know what you don't know. Ha. There was one negative review on amazon which I stopped reading after it said "YOU SHOULD READ THE CHINA STUDY" - sigh.... Even more ammo for my vegetarian boss in the gym. By not harming animals you are actually harming animals. Great. The circle of life/food chain. It's nature really, now that I think about it. Look forward to getting the book but I have about 5 others I need to read first. Not enough hours in the day.
I think Frankie Boyle (Scottish Comedian) said this, but not sure,
"There's a vegetarian option... You can f*** off!".
Apologies if that's offensive I just couldn't resist.
