We have been eating meat for centuries, and here we are today. In regards to the environment, Native Americans have been fishing and hunting and the land was full of animals, trees, and plants. It was said the sky was full of birds you couldn't even see the sky. Anyway it wasn't until the arrival of white settlers when environment was getting hurt. Mainly from the settlers chopping down way too many trees for lumber, polluting rivers with waste from mills and factors, and overhunting of animals aswell as the attempt to make the buffalo extinct to kill off the Native Americans food source. If makes you feel better the forrests are slowly regrowing in places.
Thats a very good way of looking at it. I can understand the native Americans eating meat back hundreds of years ago, thats at least better than now. But things have gotten way out of hand, it is so easy for us to not eat meat and help the environment, like maybe one day a week dont eat meat. That can make a really big difference. Personally, I myself am a vegetarian for health, moral, and enironmental reasons but its different for everyone,.
Again, if it were inefficient then businesses wouldn't do it because they wouldn't be able to make any money, so long as beef continues to be sold in the supermarket it will remain that way.
Cows are bad for the environment as well, they put out enormous amounts of methane which isn't very good for our ozone layer and stuff
I meant inefficiet for the environment, not money-wise.
