On a farm where cows freely relieve themselves as they graze, the accumulation and spread of waste often contaminates local soil and waterways. This can be controlled by confining the cows in barns, but in these close quarters their urine and feces combine to create ammonia, an indirect greenhouse gas. In an article published on September 13 in the journal Current Biology, researchers show that cows can be potty-trained, enabling waste to be collected and treated, thereby cleaning up the barn, reducing air pollution, and creating more open, animal-friendly farms.
