It literally uses more ariable land to eat meat. Chickens, pigs they’re fed grain. Most cows are too, there isn’t enough pasture on the planet to meet the demand.

Most impoverished nations are largely plant based, but neither of us live there. we’re talking about why you, an Aussie aren’t vegan.

I’m sure if I came from a culture that was different, endured hardships(like starving to death) or even just viewed them differently, maybe I would too

It’s very strange to me to suggest that whether or not it is right or wrong depends on the culture you are raised in. This has troubling implications for other acts. DV is very common in Australia, is it less wrong to beat your wife here than in Germany?

Unless you have some way to rapidly switch billions of dollar of farming industry to purely plant based industries?

we are not talking about entire industries, we are talking about you right now. Unless you mean to say you take some sort of economic catagorical imperative as a way of deciding how to act?
