A 2019 study led by Tyler Lark, an agricultural researcher at the University of Wisconsin, estimated that tillage for cropland expansion put as much carbon dioxide into the air annually as 31 million cars. A 2018 study, led by The Nature Conservancy, found that in the U.S., conserving grasslands could prevent almost three times as much carbon emission as conserving forests.
