The downside is that you won't get your money. It'll go to charity. But you'll be able to prove your point to your great-great-grandkids!
>Isn’t the trend for meat consumption to increase with wealth so as the world develops, more meat will be consumed.
Note I said "American companies", not companies around the world. I don't think my prediction will hold when applied to the entire world. I believe that within 200-300 years at the latest, there will be a strong cultural taboo in Western countries around hunting, meat farming, and eating "real meat". I figure synthetic and analogue meat will still be very popular. I don't think meat will be outlawed, but I sincerely think most people will treat meat-eaters like how most people currently treat neo-Nazis.
