Right you are and a good point. I've just come away from 5 months in South and Central America and I can tell you this is 100% true. vegetarian restaurants don't even exist in non touristy places because it just doesn't make sense for people who work 7 days a week to stop eating the animals that surround and support them.
It makes me wonder what to make of the fight for veganism in Australia with its 23 million people when almost 430 million people across the ocean have no hope in hell of turning any time soon.
Lucky for us in Australia we have a pretty good solution no one really talks about. It's called Kangaroo, better for you, the environment, impossible to farm and as an actual pest the ecosystem benefits from the hunting of them. Obviously not a solution if the eating of living beings is what irks you.
