I keep getting ads saying things like "landfills produce more methane pollutants than 56000 cars" or "tell Congress to fix this one methane leak." I also hear people bring up farming cows as a counter-arguement for any climate action (but not as a "let's fix this" type arguement sadly). So my thinking is why aren't people trying to harvest methane and use it for something? Is it inefficient? Are they stupid?
