"It's far harder" doesn't mean anything. Everything is hard before you've figured it out. Then it's easy. Cholesterol is always bad.
It actually does mean something. When eating proteins you only actually get as much as whichever amino acid you get the least of. There is nothing wrong with eating meat.
There are dozens of things wrong with it. We only do it because we are used to it. The only negative aspect of a vegan diet is the learning curve of a few months. Then it's all win.
Saying the world should suddenly abandoned everything about its past because of very recent changes is plain wrong. Progress, yes. Abandoning the past, no.
If customs are found to be bad they should stop. It's not going to happen all at once of course. Demand for animals will start falling. I predict +50% vegans in the West in 2050.
I'm sure it's a problem, in some sense, but problems can be solved. Technology will advance agriculture to the point where soil is not needed. Decimating primeval rainforest =not cool.
That that up with the government of those nations. It means absolutely nothing to the subject of how people elsewhere should eat. Cattle grazing is very efficient in some places.
It is fixing it. They mostly grow sugar cane, and with selling that internationally make enough to import other goods. They also grow some produce and let cattle graze.
It is pompous to say we only eat meat because we are use to it. It is a very new thing for food to be shipped across the world fast enough to not spoil.
Pompous or not, it's true. Shipping isn't that new, but it's here now. Going forward agric. will move indoors w 24h artificial light and blow today's technology away re efficiency.
