原文/Part4

A few hours of heavy rain in North Dakota are all it takes to change the dry earth of the U.S. prairie into thousands upon thousands of small wetlands.

But to North Dakota farmers, these wetlands can be an enemy. The muddy areas slow down tractors and other farm equipment. They can also limit crop production.

Barton Schott, afarmer, emptied several wetlands this summer to improve the fields he plans to pass on to one of his sons.

Schott pointed at fields with what he called “nuisance wetlands” as he drove his truck down a dirt road.

“We have to make bushels for you guys. I just want to make the land better,” he says.
