The Environmental Education Exchange is a nonprofit 501(c)(3) organization established to increase environmental literacy. Since 1991 the Exchange has developed a wide variety of conservation and environmental education programs and materials. Topics and themes for programs have included water conservation, recycling and waste reduction, biodiversity, endangered species, land use issues, commercialism and the environment, air quality, Sonoran Desert ecology, solar energy, mining and minerals, science literacy, special multicultural/border programs, renewable energy and more. The majority of resulting programs and materials are available free to educators or other intended audiences. Because the Exchange specializes in program design (and is not primarily a program provider), these products generally are distributed or presented by partner agencies and organizations for which they were developed.
