Over the past weekend, President Barack Obama took a break from the heat — literal and political — to take his family on a whirlwind tour of two national parks in the western United States.
Mr. Obama used his trip to Grand Canyon and Yellowstone to highlight the importance of parks to America’s heritage. (He was heard to pronounce the Old Faithful geyser in Yellowstone “cool.”)
But to the world at large, Yellowstone also carries a deep significance: When it was established in 1872, it was the first national park ever created. A movement was born.
“It’s been one of the great ideas that the U.S. has nourished here at home and stimulated others to follow,” said Bill Eichbaum, a parks expert at the World Wildlife Fund.
