In recent years, dust storms have returned, driven mainly by drought. But Shook — and others — say farmers are making the problem worse by taking land where grass used to grow and plowing it up, exposing vulnerable soil.
"The first soil storm that I saw was in 2013. That was about the height of all the grassland conversion that was happening in this area," he says.
This is where federal policy enters the picture. Most of that grassland was there in the first place because of a taxpayer-funded program. The U.S. Department of Agriculture rents land from farmers across the country and pays them to grow grass, trees and wildflowers in order to protect the soil and also provide habitat for wildlife.It's called the Conservation Reserve Program, or CRP. Ten years ago, there was more land in the CRP than in the entire state of New York. In North Dakota, CRP land covered 5,000 square miles.
But CRP agreements only last 10 years, and when farming got more profitable about a decade ago, farmers in North Dakota pulled more than half of that land out of the CRP to grow crops like corn and soybeans. Across the country, farmers decided not to re-enroll 15.8 million acres of farmland in the CRP when those contracts expired between 2007 and 2014.
The Dust Bowl forced tens of thousands of farmers to migrate and gave us the term "Okies." Are we in for a repeat?

What t-3 wrote applies to crops are grown to feed livestock just as much as it does to crops that humans eat directly. In the United States,

Except that for most of their lives, these livestock eat range grass (which needs it, as it evolved to be grazed); grain is used only for finishing and supplements.
And there is no Alkibiades to come back and save us from ourselves.

You appear to be suggesting that the use of crops as animal feed is incidental? Alfalfa
(not a grain) is mainly grown for livestock:

"Most of" 90 million acres, most of 26 million acres, most of 85 million acres--altogether they're not incidental in a country that has ~408 million acres under cultivation.
Is the quote below incorrect?

The paragraph before that one said that in the world as a whole, cattle are typically raised entirely on grass. If the bit I quoted is correct, doing that in the U.S. would mean drastically less beef would be produced there.
I gather that, in the U.S., chickens and pigs are raised mainly indoors and that sheep, goats and horses aren't eaten very much.
