Researchers discovered a pink seaweed that ‘completely knocks out’ greenhouse gasses expelled by cows
Climate change deniers often mock the claim that gas expelled from cows, either through the mouth or the bottom, is a major cause of global warming.
It was even a point of debate when Republicans were discussing the Green New Deal.
Democratic candidates continue to push the Green New Deal which could cost as much as $93 trillion, kill tens of thousands of jobs and devastate Iowa's economy. It could even go as far as banning cow farts!

But it's true. According to the United Nations, livestock farming produces about 18% of environmentally damaging gases — and about a quarter of that chunk comes from cow emissions.
When cows digest food in their intestines it ferments, which causes them to expel methane. When methane is released into the atmosphere without being burned off, it absorbs the sun's heat, warming the atmosphere.
