I don't think it would be a huge challenge for the British to drink less tea, the Japanese to eat less rice and Indians to use less cumin if continuing to eat, drink and use them would pose a huge risk for the future of all humanity. All of that (and also eating less meat) can be done without damaging the culture around it. What's much more challenging is to make people care about danger enough to be willing to change their personal behavior even in slightest ways. > Do you think the above are equivalent to what you're asking regarding meat? Why or why not? Of course it's not equivalent, because this thread is explicitly not about giving up meat consumption.
