Programs offer a mix of community service and recreation.
Past projects have included building a vocational training center for street children on the Amazon, building additional rooms onto a health clinic in the Bolivian Andes, and doing some historic preservation and environmental cleanup in the Greater Yellowstone Area. Volunteers do not need any special skills, just a willingness to help. Over 160 research expeditions in 60 countries on topics such as archeology, wildlife management, ecology, ornithology, and marine mammalogy. Volunteers aid scientists in all aspects of research. English as a second language or community development initiatives all over the world.
