"No species on Earth drinks the milk from another species, except humans (of some agrarian cultures). How did humans survive, even stronger and healthier, before the agrarian revolution?"
I just read this. And asked myself, is this true? I know ants drink the milky substance from lice. Cats drink milk. Also there are stories about animals raised by mothers from a different species.
Do you have some data on animal drinking milk from another species? I want to get clear on this vegan/ vegetarian argument.
There are still new species discovered every year...so what do we know? here is a sneaky answer to this topic. Some animals like seagulls are watched stealing elephants' milk... http://www.thenakedscientists.com/HTML/content/latest-questions/question/2863/
The second topic. How Humans surived stronger before the agrarian revolution? There were several agrarian revolutions?
One was called the green revolution in the 1960s' where the chemical fertilizers were used massively. Probably she means the agrarian revolution in the paleolithic time. Were the people healthier? A lot of healthy and fit people from India and China who are doing agriculture are very fit and healthy.
Probably she means the big scale agriculture. Such people often support Permaculture and Forest Gerdening. And don't like Big scale Agriculture, even organic. A mixture of hunter gather culture and permaculture is a good utopia for them.
