Now calculate the use of the agricultural machinery to get the same number of calories from plants. I have no idea how cows "spoil land and water". Have you seen a cow?

[jedberg]

No one ever said plant based food is carbon neutral. But it uses way less carbon than cows. And yes, I've seen a cow. Many. They spoil the land by trampling it and the water by having their excrement run off into it.

Oh man… wait ‘til you find out where fish excrement goes. No such thing as unspoiled water by that definition.

A single cow eats many times the calories it is worth before it is ready to be eaten.
