A、They do a great job in protecting animals. B、People should give more money to these charities. C、The number of these charities

W: What do you think of the way people use and treat animals?
M: Well, it depends. When we raise animals for food, the conditions they live in are often poor.
W: (11)Perhaps people should stop eating animals. To ensure our food supply, we could grow more crops.
M: That makes sense in a way, but what would you do with all the animals? You couldn’t just let them go. Otherwise, (12)some people would still hunt them because meat has become a basic part of our diet.
W: We could provide them with better conditions, anyway. We should try to improve the conditions at zoos and to recreate natural living conditions as much as possible.
M: That’s true. I think zoos are a good idea.
W: Yes. I love going to the zoo. I don’t like animal experiments, though. I believe that we can do tests in other ways.
M: (13)I read that the number of animals being used in experiments is falling dramatically as new techniques are introduced.
W: That’s good news. The good thing is that most people treat their pets well. By the way, have you ever given money to any of the charities that take care of animals?
M: Yes, I have. (14)They do an excellent job in animal protection.
