　　Keeping Pets
　　There is no denying the fact that keeping pets is a hotly debated topic today. Some people claim that keeping pets is a good thing to do. They believe that pets, like cats and dogs, can help relieve the loneliness suffered by senior citizens and other social members who are confined to their homes for this reason or that. They also argue that keeping pets helps mankind understand animals’ world and develop positive feelings toward them.
　　Others, however, hold the opposite view. They regard keeping pets as a useless but harmful thing to do. First, pets can transmit diseases. Secondly, the noises and dung of pets are sources of pollution. Last but not least, as many rare birds and animals are kept as pets, they will surely be hunted on a large scale, which means a threat to the balance of the ecosystem.
　　Weighing the arguments of both sides, I am inclined to agree with the latter. Anyway, we can lessen our loneliness and express our love toward animals in other ways. And it is my belief that only by placing man and other species on an equal basis can we expect to have a lively and colorful world.
