Tat, I think you took a very interesting approach to viewing nature--getting down to the details that a lot of us overlook or don't even think about. This doesn't necessarily relate to this paper, but I think you should also write a paper comparing nature in Hong Kong to nature here. Also, how the cultures differ in their view of nature and its importance in the world. I think you would have a great perspective on that to share with people. Maybe you could elaborate more on your discussion about stars. That is an interesting part of nature that no one has discussed so far. Great job Tat!
