Wildfires in Alberta, Canada's largest cattle-producing region, have forced the evacuation of nearly 30,000 people and burnt over 400,000 hectares of land. Rancher BJ Fuchs and his son evacuated their herd, but are not out of danger yet. The fires, likely caused by a combination of lightning and human activity, are part of a series of extreme weather events hitting Western Canada due to global warming. Farmers and ranchers are taking measures to protect their livestock and crops, and transporting cattle to emergency spaces.
