farming
Are Kansas and Nebraska this way as well? The last time I saw any pictures of them they were still pretty flat and farmy. And from personal experience I know that north-western Ohio is still almost entirely farm land.
I think farming is becoming more of a commercial business now than a personal endeavor. Fewer people want to be farmers, but there are also new technologies that make it possible for one person or a computerized machine to farm a huge area in much less time than previous eras. This makes it possible for companies to run farms instead of a single person devoting his life to it. America's farms produce enough to feed the world and then some, so I don't think we have to worry too much about a losing food, just losing the nice countrysides and persona of the farmer.
