Feeding cows seaweed could cut their methane emissions by 82%, scientists say

Researchers found cows belched out 82% less methane after putting small amount of seaweed in their feed for five months

Feeding seaweed to cows is a viable long-term method to reduce the emission of planet-heating gases from their burps and flatulence, scientists have found.

Researchers who put a small amount of seaweed into the feed of cattle over the course of five months found that the new diet caused the bovines to belch out 82% less methane, a potent greenhouse gas, into the atmosphere.
