Without sheep, there would be less meat and wool available for human use, which would have led to higher prices and shortages of these resources. This would have made life more difficult for people all over the world, especially in poor and developing countries.
In addition, sheep are also used for other purposes, such as transportation and milk production. Without sheep, these activities would have become more difficult or impossible, further impacting human society.
Overall, if man had not protected ewe, the world would be a very different place. The ecosystem would be out of balance, there would be less food and wool available, and life would be more difficult for people all over the world.
