A team at Penn State received a $25 million grant from the U.S. Department of Agriculture to study reduction in dairy farm methane emissions by using what the agency calls “climate-smart” practices.
Overall, livestock production accounts for roughly 15% of greenhouse gas emissions, with the bulk of that coming from cows and their burps. But in response to that fact, a surprising fix — mixing in powdered red algae daily into traditional cow feed — has been discovered.
As a result of rising global temperatures, the heat stress of livestock, which arises from combinations of air temperature, humidity, solar radiation, and wind speed could increase.
A nearly $120 million settlement, if approved, aims to mitigate the climate impact of one of the largest U.S. natural gas leaks. Its method is raising some eyebrows.
