Separately, the average medium-run second-order benefits of veg*nism as such can’t be that huge, given that there are already hundreds of millions of vegetarians in the world. If the average second-order effects of vegetarianism had benefits 100x greater than the direct dietary effects, then the total benefit would be larger than eliminating all meat consumption worldwide. And yet that hasn’t happened, so the average second-order benefits have to be much smaller, although they will be higher in particular circumstances.
Not sure I follow. How do we know that the hundreds of millions of vegetarians are not the 2nd order effect of a few millions being persuaded to give up animal products?
