See if you and some students can calculate how many more
animals experience life because humans eat meat, than would
if humans did not.

Given all the factors involved that is impossible to determine, besides, the
sheer number of animals who "experience life" is not important to anyone
with half a clue. What matters to people of good faith is that animals who
are raised by humans are well treated, and that our actions do not cause
undue harm to the environment.
