Bill Gates wants to reduce methane from cow burps

Cows, deer and goats on farms create a lot of gas. A lot of the world's methane is from farm animals. Methane is the second most common greenhouse gas. Bill Gates wants to help reduce it. He put money into a new technology company called Rumin8. It made a seaweed-based food. This will cut the methane in animal burps.

Bill Gates started Microsoft. He thinks farming animals less will help the environment. A third of all greenhouse gas emissions is from farming animals. Mr Gates' spokesperson said Rumin8 offers a low-cost answer to reducing greenhouse gasses. He added that Rumin8 would help farmers all over the world.
