Younger people are generally more openminded. Older people are generally more knowledgable. but it is generally not a good idea to base opinions on generalities.
I see a lot more older people at protests and marches. Might just be that is because I am one of them. or it might be that us retired folks have more time. but surveys do show that many young people are apathetic. but that is supposed to be changing.
The % of vegans is a low number. but I think that is because in polls and surveys you have to be a "self-identified" vegan or vegetarian. And as we have discussed in other threads the vegan label is pretty restrictive. When you start including vegetarians, pescatarians, vegantarians, flexitarians, reductarians, climatarians, etc in the mix it climbs up - maybe into the teens.
Since only vegans ( the lactose intolerant and a few menopausal women ) exclude dairy from their diet. And I don't think the number of lactose intolerant is increasing, the dairy aisle is my favorite indicator. I started excluding dairy 20 years ago and there wasn't even a shelf of nondairy products. Today there is a whole section. Back then it was just a couple of types of soy milk. Today we have soy, almond, pea, coconut, oat, cashew, macadamia, etc. Although all these newcomers are giving the squeeze to soy.
But getting back on topic. Another thing I see in the news is that when livestock escapes the police or FD that captures the animals never bring them back to their former owners. They usually bring them to an animal sanctuary. I'm not exactly sure what that means or indicates but it is just another crazy thing.
