This is one form of climate change mitigation.
The significance of cow farts and burps to climate change:
“Ruminant animals are responsible for roughly 20 per cent of greenhouse gas emissions globally, so it’s not a small number,” said Kinley, an agricultural research scientist now working at the Commonwealth Scientific and Industrial Research Organisation in Queensland, Australia.
“We’re talking numbers equivalent to hundreds of millions of cars.“
How seaweed comes to the rescue?
Joe Dorgan began feeding his cattle seaweed from nearby beaches more than a decade ago as a way to cut costs on his farm in Seacow Pond. He was so impressed with the improvements he saw in his herd, he decided to turn the seaweed into a product.
“There’s a mixture of Irish moss, rockweed and kelp, and just going to waste,” he said. “And I knew it was good because years ago, our ancestors, that’s what they done their business with.”
Then researcher Rob Kinley caught wind of it.
The agricultural scientist, then at Dalhousie University, helped test Dorgan’s seaweed mix, and discovered it reduced the methane in the cows’ burps and farts by about 20 per cent.
Kinley knew he was on to something, so he did further testing with 30 to 40 other seaweeds. That led him to a red seaweed Asparagopsis taxiformis he says reduces methane in cows burps and farts to almost nothing.
While it’s difficult to consider a post with ‘farts’ and ‘burps’ seriously, the impact of this research is actually very impressive. 🙂
