David A Pietz 

Hello, and welcome!  I am an environmental historian of modern China, with a research emphasis on water.  Like many of my colleagues at the University of Arizona, I not only love to research, but I also love to teach.  If you have a moment, please explore my site.  And if you have a question or comment, drop me a note!  Please read on to learn about these dolphins.
