Canadian farmer's discovery may become a game changer

U.N. says the strongest lever we have to reduce global warming is to curb the emissions of the greenhouse gas: methane. But emissions continue to accelerate.
Dorgan, who founded North Atlantics Organics, which produces and distributes organic seaweed, stumbled upon what is nothing short of a climate miracle — the seeds of which were planted through five generations of family farming along the shores of Prince Edward Island. Back then, farmers harvested seaweed for feed and fertilizer. He sent samples of it to Dalhousie University in Nova Scotia to test for organic certification. Through that, it was discovered that the high uptake of natural vitamins and minerals in seaweed drove up reproduction and milk production in cows.
While there's lots of optimism for this seaweed product, critics say it hasn't yet been proven at scale. It's clear that methane reduction from seaweed is effective in the short-term, but there's some fear that its effects may diminish over time as the cow's digestive systems adapt.
