Cow Flatulence Tax Tokyo's scientists are trying to stop global warming, one toot at a time. A key producer of methane, cow flatulence is leading cause of global warming. Their slow digestion, mixed with a gas-producing diet of greens, causes excessive methane build-up. The issue is compounded by slaughterhouses, which store thousands of cows in one location, creating large clouds of methane. Neighbors and environmentalists frequently complain about the odor, as well as the negative effects on air quality. Ireland and Denmark, along with other EU nations, have begun taxing cattle owners on cow flatulence. The "byproducts" of livestock like cows are responsible for approximately 18% of the greenhouse gases that are causing global warming, according to the Food and Agricultural Organization of the UN. Just $18 per cow in Ireland, cow flatulence will cost Danish farmers $110 per cow. Sijui ikifika kwa Wamasai na Wamang'ati wetu itaendekaje. Staajabia kodi nyingine .
