Sure, the US does. Go and look at dairy imports/exports. We farm a lot because we also export a lot. At least, that's been my working understanding. My parents have a dairy near them, nearly 8,000 head of cow, all of the milk production is sent to the Netherlands.

FWIW, when my grandparents ran a dairy, in the 40s-70s, they peaked ~300 head of cow and all production remained local -- within 50 miles of the farm. They went out of business because they couldn't compete with the global producers. The farm was eventually sold at auction to a coal mining operation.

If the world wants to engage in better farming practices, it's a global problem. It's not going to be solved by Americans alone.
