Earth Island Institute (EII) was founded in 1982 by veteran environmentalist David R. Brower (1912 - 2000) to encourage the efforts of creative individuals on critical ecological issues. EII supports diverse new initiatives and provides a stable base for on-going projects. This network of 60 projects shares central resources and benefits from the synergetic exchange of experience, ideas, and energy. EII has been widely recognized for its unique organizational model that "reduces, reuses, and recycles" resources, freeing individual projects to communicate with their constituencies and to respond quickly to evolving environmental and social justice challenges. Earth Island continues its pursuit of David Brower's ideal of Global CPR -- conservation, preservation, and restoration for planet Earth.

Save the Bay™, and keep it saved, as defined by reaching a 70 on CBF's Health Index. The Chesapeake Bay Foundation's (CBF) mission, simply stated, is to Save the Bay and keep it saved. We define a Saved Bay as having a score of 70 (out of 100) on CBF's State of the Bay health index. Thanks largely to a dramatic reduction in the amount of pollution entering the system, at 70, the Chesapeake Bay and its tributary rivers will be highly productive and in good health as measured by established water-quality standards. The result will be clear water, free of impacts from toxic contaminants, and healthy oxygen levels, able to support living resources in all parts of the Bay.
