After humans began herding cattle, it became tremendously advantageous to digest milk, and lactose tolerance evolved independently among cattle herders in Europe, the Middle East and Africa. Groups not dependant on cattle, such as the Chinese and Thai, remain lactose intolerant.

Climate alone does not dictate yields; political shifts, global “demand, and agricultural practices will influence how farms fare in the future.
