I loved the line where the scientists ponder why adding seaweed and canola oil reduced how much food the cows ate. Maybe the cows just hate your stank food?

Even if the red seaweed supplements worked there would be no way we'd be able to supply enough to actually make a difference to the dairy industry's emissions. It's also used to greenwash dairy, completely ignoring the non-methane harms it causes including deforestation and emission of cancer-causing ecosystem-destroying runoff into water supplies and river systems.
