2/ This answers a question I'd had for a long time. When we learned about the 1847 famine in schools, the textbooks would say "People got almost all their calories from potatoes, and their fat and protein from a little bit of dairy." But I knew cows are big honkin' animals that need lots of space and food.
If people were living on tiny plots, how were they keeping cows?
Oh the cows were little. That helps a lot.
