Cattle agriculture is not cows. It's human beings farming cattle. Also, they are only regenerative under certain conditions. Cows are especially bad in wet soil areas and they can damage the area reducing plant growth through pugging. This can cause soil runoff and flooding. In addition, cattle will displace native flora and fauna.
