Dear editor，
I'm sorry to occupy your precious time, and I really want to tell you anything about the problem of some people keeping too many pets nowadays. I take the problem more and more seriously for following reasons.
First of all, as it is known to people, pets make so much noise that trouble residents a lot. What's more, it is widely accepted that animal waste pollutes the environment, where makes people quite uncomfortable. Many owners like taking their pets to public place where they may frighten children or even bite people. The mostly important is that pets can spread some diseases and this has attracted much attention.
Take all these factors into consideration, I sincerely hope that I can get help from you and expect the media do something for this.
Yours truly’
Wang Lin
