I've seen some folks turning to vegetarianism as an attempt of virtue-signalling, even here in Rio Grande do Sul where beef is part of our culture. Anyway, I actually prefer fish, since I lived in cities with a fishing tradition and got quite used to that, even though the higher organic matter to protein conversion ratio is obviously another good argument from the "sustainability" standpoint and eventually might lead fish to become more cost-effective than beef in some years. When it comes to vegetable protein sources, I usually eat corn, beans, and chickpeas, but I don't use it as a replacement for meat.
