David
Ross Brower was a leading environmentalist who was dubbed "the
most effective conservationist in the world". He helped create
some of the most widely known and effective environmental organizations,
including the Sierra Club Foundation, Friends of the Earth, Earth
Island Institute and the League of Conservation Voters. In his
younger years, David Brower was a noted mountaineer, and this
helped shape his love of nature and desire to protect biodiversity
and natural habitats. David Brower's ideas and views influenced
UNESCO's creation of a system of World Heritage sites, which lists
and conserves international sites, such as forests, rivers, mountains,
buildings or cities, that are significant to humanity's common
heritage.
