Meat eating is actually a very cultural thing.

In India, for example, there is an area where most people are vegetarian and have been so for centuries.

My point about how people are psychologically pushed to consume also applies here.

Further, excessive meat eating (and the average meat consumption in most Western countries is at those levels) is actually bad for one's health and life expectancy, so even from a pure individual selfishness point of view people aren't doing what's best for themselves, which would indicate there's more to it than merelly individuals being selfish.

That said, I agree that people should eat less meat, it's just the expectation that they're informed enough (at various levels) to do it that I find unrealistic.

It's another of those things which in order to change needs to be pushed as education to all of society, while what we really have is massive economic interests pushing in the very opposite direction.
