It should very much be possible. Anecdotally, India has huge number of people who don't eat meat and the vegetarian food is pretty delicious. But perhaps its just because I grew up eating that food.

The problem is probably that innovation in non-meat based food hasn't happened very much in the US. But I do see that changing with Amy's kitchen and all the vegan/veggie restaurants that are springing up.

My personal feeling is that lab grown meat and meat substitutes are probably the best way to get around this rather than moralizing about it, which never works.

Disclaimer: I'm definitely a meat lover, but do try to eat less meat whenever I can.
