Dear Mr. Leung Chun Ying, In Hong Kong the pollution exceeds safe levels almost every single day. And most of it comes from cars, buses, trucks and other transportation. The reason transport, say cars, pollutes so much is that they use un-environmentally-friendly fuel, such as diesel. Mr. Leung, if you really care about us Hong Kong people, please listen to us and make environmentally-friendly fuel cheaper, so that 7 million people will no longer have to breathe polluted air again. The lives of everyone in Hong Kong, especially children, the elderly and pregnant women, as well as people with respiratory diseases. Show you care. Make environmentally-friendly fuel cheaper. The eyes of the world are on you. Please, Mr. Leung, please do the right thing for Hong Kong.
