Feed Additive Squelches Ruminants' Methane Belches. 

The global population is now nearly seven and a half billion. And that’s just humans. Because our planet is also home to one-and-a-half-billion cows, another billion sheep, and a billion goats. Their combined belches account for a full fifth of the world's methane emissions—and methane is about 30 times more potent at trapping heat than CO2.
But those methane emissions might get cut—by feeding the grazers something called 3-nitrooxypropanol. "I can tell you, they like it. No rejection at all." Maik Kindermann, an organic chemist at DSM Nutritional Products in Switzerland. Liking it, in the cow world, he says basically means they'll still gobble up their food, even with this stuff mixed in.
Kindermann's company developed the additive a few years back. It jams up an enzyme crucial to the production of methane by bacteria that live inside the animals. And it slashes the number of those methane-belching bacteria, while leaving the rest of the microbiome intact. The result? A 30 percent decrease in methane emissions.
Kindermann says he thinks the compound could be a winwin for the planet—and the animals. "You know the methane is kind of a waste product. And this energy, instead of losing it for the animal, it can be reused for the animal in terms of performance, and at the same time we are doing something for greenhouse gas emission and climate change." The product’s not on the market yet—toxicology tests are ongoing. But the hope is that it might take some of the heat off of beef.

It is true to affirm that
1) methane is less harmful than CO2 when it comes to heat trapping. 2) goats, sheep and cows account for 25% of the world’s methane emissions. 3) the population of cows outnumbers that of goats or of sheep. 4) the population of humans exceeds that of all animals on the planet. 5) methane is more dangerous for the planet than carbon dioxide gas.
