This is the video page. Most of the videos have been made by me, though a few such as Rivers in Peril have been made by colleagues and I simply host them. Beginning July of 2009, I began to document some of my trips through short videos that describe special freshwater ecosystems of the world and the challenges they face — as well as the challenges of the people living in these places. These are my earliest attempts at producing videos, so I ask that you be patient with their numerous imperfections. Feedback appreciated!
