How is that strategy sound in the least? What's your plan to convert billions of people to stop eating meat?

The objective here isn't to convert a few people on hacker news, it's to convert billions. "Hey dummies, just eat plants! They were here the whole time!" isn't gonna happen.

I'm replying late but...By "strategy" here I'm referring to the strategy for humans to eat less meat to achieve environmental goals — not any particular strategy to achieve a reduction in meat eating. I agree that achieving that outcome is going to be hard.

Well I'm talking about both money and environmental costs, and we haven't done very much toward reducing the latter. I'd rather put a bunch of effort into reducing environmental impact than "just" eat traditional vegetables.

When you say "until we fix those problems" you're suggesting a very different strategy from "just" working around it with no notable effort to do anything else.
