Summers Henderson produced, directed and edited this 15-minute documentary, along with Gary Ashwal and Laura McLam. The film introduces the problem of phosphorus pollution in the Mystic River watershed, near Boston, Massachusetts. This pollution can lead to eutrophication -- an over-growth of plants and algae that robs oxygen from the animals in the river. The filmmakers identify the main sources of pollution, while keeping a sense of humor about the problem and some possible solutions.
Summers made "Green River" for the "Filmmaking and the Environment" class, as part of the Master of Arts in Media Arts program at Emerson College in Boston. The film screened at the Boston Museum of Science.
