"We treasure pictures and sculpture. We regard Attic temples and Roman triumphal arches and Gothic cathedrals as of priceless value. But we are, as a whole, still in that low state of civilization where we do not understand that it is also vandalism wantonly to destroy or permit the destruction of what is beautiful in nature, whether it be a cliff, a forest, or a species of mammal or bird. Here in the United States we turn our rivers and streams into sewers and dumping-grounds, we pollute the air, we destroy forests and exterminate fishes, birds and mammals — not to speak of vulgarizing charming landscapes with hideous advertisements." — Theodore Roosevelt
