Dear Joe,

How are you? [通常我們不會自問自答 how r u -> im fine 的] I have been to Hong Kong. There are pollution problems in this city.
There are a variety of pollutions, such as water pollution, air pollution and so on. Let me describe these pollution in detail. [用first, second... 會清浙d] First, the water pollution. People in Hong Kong throw a lot of trash to the sea water. The trash causes the water surface dirty. Second, the air pollution. Hong Kong has a lot of industry factories and commerce offices. They emit a lot of noxious gases, thus Hong Kong's temperature rises. It is the famous 'greenhouse effect'.
[講完各種污染, 開新段講處理方法]
To solve these pollution problems, we should try our best in the following ways. We should not throw trash to the sea. We should plant more trees to improve the air quality into fresh. We should not waste the water.
[Sorry 最尾呢句 唔係好get到你想講d乜]
