This Febuary, the Egg Board reported over 8 and a half Billion eggs produced in America. (I looked this up because of a #GoVegan eco-idiot who apparently saw The Daily Show.)
What's the current human population of the Earth? (<8 Billion.) That's 1 specie, in 1 month, in 1 country. If we just stopped eating meat (And eggs) we could be wiped out by famine, and overpopulation of feral chickens (hogs, cattle...) In under 9 months, those 8.6 Billion eggs can hatch, and grow old enough to start laying eggs, at INDUSTRIAL production rates. Before you can knock up your wife, and have an infant.
Also, we can't stop world hunger, it wouldn't be profitable. We can make an egg for every man, woman, and child on the planet, each month, but we can't stop world hunger. Also, there's a record breaking Dairy surplus, that's probably going to all rot, because of tariffs, and Brexit, there's no market for it.
