1) In my opinion, animals should not work. I consider all animals to be as free and intelligent creatures as humans. People treat them terribly in any field of work. In the circus and the zoo, animals are beaten, not adequately fed and kept in captivity. Technological progress does not stand still. For example, instead of horses, you can move around by car, bicycle, train, etc. We must refuse to use animals in work.
2) My favorite animal is a dog. They are very smart and knowingly say that the dog is a friend of man. There are a lot of dog breeds and each dog has its own character, so everyone can find a four-legged friend.
3) Humans are not the only smart creatures on the planet. Thinking and logic allows animals to survive. I think that now elephants and other smart animals are used only as toys in a circus.
