Environmental education can take many forms. The Arm-of-the-Sea Theater Company has developed a rich tradition of using art and theater to address issues of nature, ecology, and environmental ethics.

The troupe has taken on challenging topics not typically found in theater, including photosynthesis, pollution, and the nitrogen cycle. This year the company is heavily involved in the Hudson Quadricentennial events, enacting a play entitled "Mutual Strangers: Henry Hudson & the River that Discovered Him."
