An author claims that "zoos do more good than harm." The author provides the following as support for the claim:

I believe zoos are great because they give animals exactly what they need. I have seen caretakers feed animals and give them medicine when they are sick. I have watched zookeepers cuddle baby monkeys and place blankets over cold piglets. They train animals to do tricks, too, so that the animals have fans who love and cheer for them. I am sure this makes the animals happy.
