[EX Q]: Person1: What do you think of the way people use and treat animals ?
Person2: I think most people treat animals well , but we are often cruel to animals . When we raise animals for food , the conditions they live in are often poor .
Person1: Perhaps people should stop eating animals . We could grow more crops .
Person2: What would you do with all the animals ? You couldn ' t just let them go . Besides , some people would still hunt them . Meat has become an integral part of our diet .
Person1: We could provide them with better conditions anyway . We should certainly try to improve the conditions at zoos . We should try to recreate the natural conditions as much as possible .
Person2: That ' s true . I think zoo are a good idea , because they allow people to get close to animals . I think it ' s good for kids to see wild animals .
Person1: I agree . I ' m an adult and I love going to the zoo . I don ' t like animals experiments though . I believe that we can do tests in other ways .
Person2: I read that the number of animals being used in experiments is falling dramatically as new techniques are being introduced .
Person1: That ' s good news . The good thing is that most people treat their pets well .
Person2: Sometimes you read about people who have been cruel to pets or other animals , but those stories are rare .
Person1: Have you every given money to any of the charities that take care of animals .
Person2: Yes , I have . They do an excellent job .
