Dear editor:
Recently we have had a heated discussion on whether people should keep pets at home in cities.
Some students think it's a good idea to keep pets because many old people who live alone at home can get some comforts from pets. Besides , getting along well with animals will make our life interesting. On the contrary the other students are against the idea. In their opinion if too many people keep pets at home, it's bad for the environment. What is worse, pets may make too much noise and even attack people.
I like animals, so I don't think it's bad to keep pets at home. But we must take some measures to prevent them from polluting our environment.
