C-WIN is a statewide nonprofit dedicated to equitable and sustainable use of California's water resources. Both our Board and Staff members provide the environmental community support and leadership on enforcement of the state's Bay-Delta public trust responsibility, on stopping irrigation of naturally contaminated farm lands in the San Joaquin Valley, and on the speculative water practices of federal and state water projects in California. We educate the public about public trust resource and California's constitutional prohibition of waste and unreasonable use of water, and about alternatives that restore rivers, fisheries, and other public trust resources.

Founded in 1993, Los Angeles Waterkeeper’s mission is to protect and restore Santa Monica Bay, San Pedro Bay, and adjacent waters through enforcement, fieldwork, and community action.

The Long Now Foundation was established in 01996 to develop the Clock(http://longnow.org/clock/) and Library projects(http://www.rosettaproject.org/), as well as to become the seed of a very long-term cultural institution. The Long Now Foundation hopes to provide a counterpoint to today's accelerating culture and help make long-term thinking more common. We hope to creatively foster responsibility in the framework of the next 10,000 years.

The Indo-Pacific Conservation Alliance (IPCA) is dedicated to the study and conservation of the native ecosystems of the tropical Indo-Pacific region and support for traditional peoples in their stewardship of these globally significant natural resources. Our current field projects are located in Indonesia and New Guinea. Our main program is with the Asmat community of southwestern Papua, Indonesia, in the lowlands of Lorentz National Park, a UNESCO World Heritage Site, and the largest and most diverse protected area in the Asia-Pacific Region. Our conservation successes include halting destructive commercial logging and fishing operations. IPCA is based at the Bishop Museum in Honolulu, Hawaii. Rather than establish in-country offices, which is both expensive and unnecessary, we work with and through local partners to minimize overhead costs and put financial resources into the field where it is urgently needed. IPCA was formed in 1998 in collaborative association with scientists from the Smithsonian Institution, Bishop Museum, and other leading scientific and conservation organizations. Our projects are science-based and driven by our desire to work in authentic collaboration with indigenous communities, in-country scientists, local conservation groups, and other stakeholders. Our geographic focus is on the tropical Indo-Pacific region, a vast area that includes Indonesia, Melanesia, Micronesia, and Polynesia -- by far the most biologically and culturally diverse area of the planet.

At the Center for Biological Diversity, we believe that the welfare of human beings is deeply linked to nature — to the existence in our world of a vast diversity of wild animals and plants. Because diversity has intrinsic value, and because its loss impoverishes society, we work to secure a future for all species, great and small, hovering on the brink of extinction. We do so through science, law and creative media, with a focus on protecting the lands, waters and climate that species need to survive. We want those who come after us to inherit a world where the wild is still alive.

OpEPA USA, founded in 2006, is a sister organization of OpEPA Colombia founded in 1998. The organizations were created as a means to reconnect children and adults with nature and promote positive environmental actions in Colombia and Latin America. Colombia is one of the most biodiverse countries in the world. It has an incredible wealth of ecosystems, flora, fauna and cultural diversity. However, Colombia suffers from serious environmental degradation. Deforestation, high levels of urban waste, polluted water and reduced air quality are just four of a litany of similar issues. The environmental movement in Colombia has employed the range of conventional tactics to address these issues. Public awareness campaigns have dotted the airwaves, and legislative changes have improved the legal basis for pursuing polluters. But young people, "the next generation of consumers and decision makers," cannot be scolded or legislated into caring about the environment. To truly change the way they approach environmental issues, they must feel personally compelled to transform the status quo. This is what OpEPA targets to do.
