On the College of California at Davis – 18 cows are cordoned off from others on the campus’s dairy facility. They’re a part of an ongoing collection of research to dramatically scale back the local weather influence of dairy and beef manufacturing.
Globally, cows and different livestock animals are liable for about 40 p.c of methane emissions – a potent greenhouse fuel. In digesting their excessive fiber weight-reduction plan, cows emit methane as a byproduct, making them one of many least local weather pleasant sources of meals on the planet.
