Sierra Club
"The Sierra Club is an American environmental organization founded on May 28, 1892 in San Francisco, California by the well-known preservationist John Muir, who became its first president. The Sierra Club has hundreds of thousands of members in chapters located throughout the United States, and is affiliated with Sierra Club of Canada."
Statements
"After years of debate, a near consensus among the world's scientists has concluded that we are warming the planet, and unless we take steps now to curb global warming, our way of life, our planet, and our children are all in grave danger.
"But there is hope. Each us can make simple decisions that will reduce global warming pollution. The Sierra Club's network of activists and volunteers are dedicated to curbing global warming. We are working with churches, labor unions, mayors and state governments to bring about a cleaner, smarter energy future."
