I hate this topic more than any other I've ever read on Huskerboard, because I agree with a lot of what Hedley is saying. I think there are a lot of ignorant comments on here, but I think they're mostly being made because of Hedley's post history.
The reason I don't eat much meat is because its production causes a sh#t ton of pollution (namely the cows) and it isn't as nutrient dense as veggies and fruit. I can get a lot more mileage out of fruits and veggies. People in general eat way more meat than they need to, but I understand the taste factor. It tastes great. I probably eat chicken about once a month and fish/seafood twice a week.
