Animals are a huge part of our daily lives. They provide food and clothing. They offer us companionship. They have been used for transport, farming, and construction. They protect us from other animals and our environment. They provide assistance when we are disabled. They help ensure that food, medicines, and the environment are safe for both us and our animal companions. Think of a world with no animals other than humans—it would be very stark, indeed.
