Dear Mr. Hans,

    We wish to express our concern regarding the bathroom facilities in Green Park. Because of the park's convenient location, our neighborhood children spend many hours after school playing on the playground equipment. Although we ask them to come home to use bathroom, they sometimes use the park bathroom.

    Some of us visited the facilities this morning and were horrified to see their condition. Vandals have broken the toilet, leaving a gaping hole over exposed sewer. The children claim it has been that way for weeks. The graffiti is appalling. Until something is done, the bathroom is definitely off limits for our neighborhood kids.

    Please, either enclose the facility or repair it immediately. I think it presents a clear danger to public health. You should take some acts to solve this problem. We will be happy to cooperate in any way we can.

According the writer, why should the park enclose or repair the facility?
