How is Hong Kong being affected by pollution?

The class I took was called Water. We learned about how important and scarce water really is. In this unit we learned about glaciers and how they provide a massive amount of fresh water for people around them. Unfortunately glaciers are melting at a fast rate due to global warming and they won't be around much longer. For this project we had to focus on a certain city and write about the future climate. I studied Hong Kong and learned about how there could be a catastrophe caused by global warming. We also learned about cloud types and where certain clouds form in the atmosphere. All of this content is in the project.
