SAN DIEGO — A California state law requires short-lived climate pollutant producers, such as dairy farmers, to cut methane emissions by 40% by 2030. Some scientists say the key for the cows may be found in the sea.

A team out of the Scripps Institution of Oceanography has been busy working to grow a strain of red seaweed that has been proven to curb methane that cows release every time they burp.
