Can We Fight Climate Change By Bioengineering a Better Cow?
One of Slashdot's most-visited stories of all time was the 2016 story asking: Can Cow Backpacks Reduce Global Methane Emissions? "Enteric fermentation," or livestock's digestive process, accounts for 22 percent of all U.S. methane emissions, and the manure they produce makes up eight percent more...
Using tools that snip and transfer DNA, researchers plan to genetically engineer microbes in the cow stomach to eliminate those emissions. Brad Ringeisen, executive director at the genomics institute, cut his teeth running biotechnology at the U.S. defense research agency DARPA, which helped pioneer transformative innovations including the internet, miniaturized GPS, stealth aircraft and the computer mouse. "If there is a way to redirect that hydrogen and convert it into milk, meat, wool — it would be much more accepted by farmers," said Ermias Kebreab [a professor of animal science at UC-Davis].
