### Comment:
Population pressure &amp; economics are going to force many people to go for more vegetarian diets as well.

### REPLY:
Already has! Here's an interesting stat: India's population grew and its economy expanded while per-person caloric intake declined. India's populace is primarily vegetarian, often for strict religious reasons. That same situation (economic growth, population growth, caloric decline) has never happened in recorded history!
