There is no doubt the fact that keeping pets is a hotly debated topic today,Some people claim that keeping pets is a good thing.pets can help relieve the loneliness. it will bring them a lot of fun in the part-time.however,other hold the opposite view.They regard keeping pets as a useless but harmful thing. I agree with the latter, firstly,the pets lose freedom. What a sad thing!Secondly,pets can transmit diseases.the noises and dung of pets are sources of pollution.finally,they don’t have enough space to take activity. As a college student,we can lessen our loneliness and express our love toward animals in other ways.
