It's seems obvious that if you are raised to not eat meat then you will be very unlikely to introduce it into your diet later on, especially if it is socially frowned upon. People who have been vegetarians for a long time often are unable to stomach meat. Also, it's clear that some kinds of meat are already not eaten: do you think the reason people don't eat dog in the US is because it doesn't taste good? So, while it's certainly likely that people alive today will always eat meat, generational turn-over could result in a world without meat eaters. (I eat meat but do not eat mammals.)
