What I said was that with education, outreach, and other nudges, we could, over time, affect the statistical distribution of meat consumption. Which is correct. I did not say it was easy, in fact I did not comment on how hard it would be, I just said it is possible.
In fact, fixing humanity's over-consumption of resources will be very hard. But we have no choice. We will perish if we do not. So, idk about you, but I think we had better try.
By the way, and I want to say this as a genuine bit of feedback, but it is not very interesting conversation if you are going to take what I said, turn it in to hyperbole, and then point out that the hyperbole you made up is unrealistic. I would encourage you to read comments carefully, and make sure you have really understood what the person has said. Cheers, and nice username.
I'm not saying you're wrong, because I'm aware that modern life is different from our ancestors who depended on meat, but I want you to be aware of the magnitude of the force you're fighting against, and not say "it's just cultural, so easy to change". Imagine saying "the fact that most Americans speak English instead of Mandarin is just cultural, we could literally change it overnight if we wanted to".
