The faculty here at American University's School of Communication include several of the country's leading environmental filmmakers with their work coordinated through the Center for Environmental Filmmaking. One of our faculty Larry Engel worked on the recent PBS NOW film "Waterworld" which documents how climate change is impacting Bangladesh. The film describes the human health effects that climate change is already causing in this developing country of more than 200 rivers and frequent storm surges. You can read a transcript and/or watch the film at the embed above.
You will also want to read about Engel's recent course "Practicing Environmentalism: Galapagos Islands," team taught with members of the faculty from the AU programs in environmental science and international relations.
