FDA Approves First Waste-Gas-Reduction Drug for Cattle
By Dan Nosowitz
When we think of dangerous gases emitted by cattle, the logical first thought is of methane, let loose into the air by burps and farts to contribute to climate change. But cattle are complex creatures in their diversity of noxious fumes, and the FDA just approved the first drug to treat a lesser-known one.
Cattle produce ammonia—well, sort of. According to Penn State, it would be more accurate to say that cattle are very inefficient at breaking down nitrogen, which they take in as part of their diet. They pass that nitrogen out mostly in urine, where it's reasonably harmless. But there are enzymes in cattle feces that, when they mix with cattle urine, form ammonia and ammonia is not reasonably harmless. This is a problem at its worst in indoor facilities, especially larger farms and indoor dairy farms, where liquid and solid waste combine on floors.
Aside from the fact that ammonia smells really bad and can be an irritant for humans and animals around it, ammonia can also contribute to something called eutrophication. Eutrophication is the process by which, in this case, ammonia goes into water sources and promotes the mass growth of algae and other organisms, throwing off ecosystems and sometimes choking waterways. Excess of algae on the surface of ponds and lakes can end up killing marine animals.
The FDA this week sent its official approval of a drug called Experior, the first approved drug tasked with reducing gas produced by waste. According to studies conducted by both Elanco, the company that makes Experior, and others, Experior has no known health effects on cattle, with treated cattle showing about the same growth patterns and ailments as non-treated cattle.
There are, of course, other solutions to the ammonia problem. Experior reduces ammonia production by 14 to 18 percent, according to its FDA filing. Great! But other studies have been done in which farmers simply feed their cattle less nitrogen-containing protein—primarily soy—and those studies have shown that simply a better diet can reduce ammonia by up to 40 percent. Experior seems good! But feeding cattle appropriate diets—like grass—might also be good. Or better.

First there was Fred Stone, the third-generation dairy farmer in Maine who discovered that the milk from his cows contained harmful chemicals. Then came Art Schaap, a second-generation dairy farmer in New Mexico, who had to dump 15,000 gallons of contaminated milk a day.
California Governor Gavin Newsom signed into law a bill that that bans the sale and manufacture of fur products in the state. The fur ban, which he signed into law on Saturday, prohibits Californians from selling or making clothing, shoes or handbags with fur starting in 2023, according to the AP.

During the three months of July, August and September, renewables generated an estimated total of 29.5 terawatt hours (TWh), compared with just 29.1TWh from fossil fuels, the analysis shows.

It is far too easy to view scarcity and poor quality of water as issues solely affecting emerging economies. While the images of women and children fetching water in Africa and a lack of access to water in India are deeply disturbing, this is not the complete picture.
- Mice exposed to nicotine-containing e-cigarette vapor developed lung cancer within a year.
- More research is needed to know what this means for people who vape.
- Other research has shown that vaping can cause damage to lung tissue.
A new study found that long-term exposure to nicotine-containing e-cigarette vapor increases the risk of cancer in mice.
