Bringing Back the Dust Bowl

Biofuels…is there anything they can’t ruin?

America’s prairies are shrinking. Spurred on by the rush for biofuels, farmers are digging up grasslands in the northern Plains to plant crops at the quickest pace since the 1930s. While that’s been a boon for farmers, the upheaval could create unexpected problems.

A new study by Christopher Wright and Michael Wimberly of South Dakota State University finds that U.S. farmers converted more than 1.3 million acres of grassland into corn and soybean fields between 2006 and 2011, driven by high crop prices and biofuel mandates (right). In states like Iowa and South Dakota, some 5 percent of pasture is turning into cropland each year.

It’s a big transformation in the heart of the country: The authors conclude that the rates of grassland loss are “comparable to deforestation rates in Brazil, Malaysia, and Indonesia.” And those changes are already having plenty of impacts.

Good thing Congress didn’t just continue to subsidize this madness as part of the Fiscal Cliff deal.

Four Cheers for Incandescent Light Bulbs

It brought me much -- indeed, too much -- joy to hear of the Trump administration's rollback of restrictions on incandescent light bulbs, even if the ban will remain in place. The LED bulbs are terrible. They give off a pitiable, dim, and altogether underwhelming "glow," one that never matched the raw (if ... Read More
