One Way to Combat Climate Change: A Smartphone App That Lets Farmers Control Where Their Cows Graze

A San Diego startup called Vence has created a device that can help farmers control their livestock’s movements and behavior. The new technology – a collar with accompanying software – buzzes when an animal is somewhere it shouldn’t be and shocks them if they keep going. While the practice of shocking animals isn’t universally approved, doing so can prevent overgrazing and thus improve overall land health.
