How much would giving up meat help the environment?

[Greybnk48]

78. Again, what value would a pig have if it's not being raised for meat

to sell? They would be "allowed" to go extinct at the very least if profit cannot be made from keeping them. So "saving" the animals, like pigs, would then be allowing the species to go extinct rather than eating them?

For some animal lovers, and philosophers like Hare and others, that argument seems disingenuous.

I believe that the treatment of animals that are raised for mass consumption is horrific and cruel to the point of being evil in some cases. But I also believe that we can do much to end this type of coarse and callous treatment of animals without forcing everyone to go vegetarian. Joel Salatin is someone who has worked diligently to educate people about how it can be done. There are others as well. And it's much healthier food than what we have now.
