I hope my comments h aven't come across as a rant also, but I don't share the same view of the issue as you, and am trying to share my point. I'm maybe closer to this than some, my income comes from Ag, and I've been a farm boy all my life. My Grandpa gave me a calf when I was 6 and by the time I graduated High School, I had used the progeny from that heifer to buy sell and trade to put together a 30 head herd that paid for college, a new to me pickup, eventually paid off my wife's college expenses and got she and I off to a good start in life. I owe alot of what I have to the land, and working with farmers. Often times I hold the keys to their farm profitability in my hands, this is a responsibility that I don't take lightly, nor do my peers in the industry. I also don't think that as farmers, we take lightly the roles that we have in growing food for the table. We eat it too, just remember that.
I'm not sure your definition of a industrial farm really fits. I grew up on a farm. Mom, Dad, me a bro and sis. We had a hired hand for quite some time, from when I can remember until I was about 12 or so and could do more. We farmed about 400A of rowcrop then and ran about 130 head of cow-calf pairs. By your definition...we were an industrial farm... Any successful farm regardless of size is to be ran as a business. You have to make the decisions to do the things that make you profitable, or you'll be gone. Sometimes that means hiring folks to do the basic tasks of building fence, or even driving a tractor while you as a primary operator can focus on those jobs or tasks that are more profitable. I've been talking with my FIL about this at length lately. He needs some new equipment, but I'm not sure it works out for him right now. It may be better for him to pay someone else to do those jobs for him while he does other, higher value jobs around the farm that often get put off b/c he's in a tractor seat.
I think you'll find farmers, consultants and others in the Ag industry as a whole don't take their jobs lightly. We're all tied to the land and all (or at least most all) understand that any thing we do to jeopardize the safety of the food supply will reflect negatively on all of us. We're all responsible for the quality of product that hits your table, unfortunately, there are often many steps between our farm and your table. Another real world example...my FIL sells some of his calves to a large meat processor, and also sells some direct to the consumer in 1/4-whole's. They all come from the same herd, and are all treated the same until they leave the farm.
RE: sustainability. I'm of the opinion that we have tools at our disposal today that put us in a better position to maintain the ground water quality and conserve soil than what we had even 20 years ago. Yes, some of those tools are GMO's and pesticides, but those come to us via a very heavily reviewed process. Today we're aware of soil erosion, in the past, we spent alot of time dragging a plow. Now there are many places that are using no-till to keep residue on the ground and limit erosion. No-till is also used out in the dry areas to retain soil moisture, they're not using as much irrigation water to grow the same crop. Not possible without modern equipment, herbicides, and modern seeds and traits.
Thanks for bringing up the imported food issue. This scares me. I have alot of confidence in the American Farmer, and their ability to produce a safe and abundent food supply. BUT if things change to the point where they cannot compete due to regulation or price, guess what...they will no longer be the source of what you and I eat. Your food will come from the cheapest supplier from the world market place, and not always do those suppliers have our best interests in mind or even care. There's currently regulations proposed that will require egg production to occur in open barns rather than cages. It's been proven that open barn production lowers the quantity of eggs produced/hen. This requires more barns, more hens, and more feed to maintain the same level of production. Guess what...there aren't many people in a position due to zoning, etc to build more buildings here. If this goes through, we'll go from being an exporter of eggs to a net importer of eggs on a rather large scale. Not sure how I feel about that, but I'm pretty sure buying a few hens will not solve the issue. If you've forgotten, many of our vaccines use eggs to produce them. So where will the rest of them come from, and do they have the food safety rules in place that we have? Will their eggs come from open barns or cages? I doubt it. We're going to make rules that make it not OK for our growers to use a particular practice, but will end up buying the same product produced in the manner that we outlawed...hmmm. Are we supporting the farmers that support us? Doesn't sound like it does it.
One last comment I'll add. Just saw this article and related research paper in one of my trade magazines, that might be an interesting read for you guys.
