If our meat animals didn't exist, a lot of other animals would. Animals eat a lot of food that would be available calories for other animals instead, after all.

If our meat animals didn't exist, a lot of other animals would. Animals eat a lot of food that would be available calories for other animals instead, after all. Also, never existing at all is not a negative, it is null. There is nobody to experience a negative effect of not existing. So I don't think this is a very good argument.
