改:Although H.K is too noisy,we can use smaller voice to talk and don't play the music so loudly(其實noisy多源自交通公具，所以i think 唔太適合用=])

I think the dirty air, noisy environment is bad to Hong Kong. Although the air in Hong Kong is too dirty , we can grow more plants or control the exhaust gas to pollute the air. Hong Kong is too noisy but we lower our voice in talking and at the same times not to broadcast music loudly .

I think pollution, whether it be contaminated air, or noise, is quite serious in Hong Kong. But certainly, as individuals we can do something to remedy the situation. For one, we can plant more plants in areas with busy traffic so as to clean up the dirty air. Or we can lower our voice when talking on streets, reducing chances of making too much noise. And of course, whenever we see litter, we can pick it up and throw it away instead of just stepping over it.
