Environmentalists Seek to Reduce Cow Burps and Ethanol

(p. A8) . . . a sweeping new study issued Wednesday [December 5, 2018] by the World Resources Institute, an environmental group . . . warns that the world’s agricultural system will need drastic changes in the next few decades in order to feed billions more people without triggering a climate catastrophe.
. . .
. . . the authors are not counting on a major worldwide shift to vegetarianism.
“We wanted to avoid relying on magic asterisks,” said Timothy D. Searchinger, a researcher at Princeton University and the World Resources Institute and lead author of the report.
. . .
The authors . . . pointed to possible techniques to reduce the climate impact of existing farms. For instance, new chemical compounds could help prevent nitrogen fertilizers from producing nitrous oxide, a potent greenhouse gas. And scientists are exploring feed additives that get cows to burp up less methane, another big contributor to global warming.
. . .
But, Mr. Searchinger said, many of the recommendations in the report, such as breeding new, higher-yielding crop varieties or preventing soil erosion, could also help farmers adapt to climate change.
. . .
. . . , the report’s authors call for a limit on the use of bioenergy crops, such as corn grown for ethanol in cars, that compete with food crops for land.
