since the flesh of animals yields 100 to 1000 lbs an acre, dairy products around 10,000 lbs. an acre, some vegetables, 81,000 lbs. an acre, and fruits from centenarian fruit trees 450,000 or more lbs. an acre.

Meaningless statistics. Meat production depends on the specie of animals and the method of raising it. Many times hoofstock is raised on land that is not suited to vegetable production. So that "useless" land now produces food.

And since when did Jesus become a vegetarian?! He ate fish even after he rose. And the Passover usually served lamb!

If people stop eating animals, animals are still going to eat animals. Or is some eco-nazi going to convince them to be vegetarians too?

Absolutely HAD TO serve lamb, or else you weren't eating the passover.
