Having spent significant time in the American rural midwest, the decline of the American family farmer is very evident, and the rise of factory farms of 20,000+ acres in size is imminent.  With it comes further deforestation, huge manure cesspools that often breach into streams and rivers during floods,  and copious amounts of RoundUp sprayed every season.  Most of what is grown becomes High Fructose Corn Syrup or soy-based oils for processed food.  Milk cows are pumped full of antibiotics and hormones.

In short, there's very little to emulate in the American farming model except the cheapness of the whole thing.  I'd happy pay a couple dollars more for milk and have Canada's farming system...any day of the week.
