Finished presentation and practiced Chinese during the day.  Gave presentation in the evening with the help of one of the interns as a translator.  A very good discussion followed.  One of the girls asked why so many people care about the environment and ecological damage in California. She stated that in China most people only care about the environment if people are being harmed.  I mentioned that we have problems with pollution harming humans too, but I tried to explain the importance of ecosystem health and resource preservation, and how that benefits everyone as a whole.
