Happy Earth Day! We celebrate our earth every day by conserving America’s public lands like Yosemite (pictured here). Our national parks not only create healthier communities, they also support local economies. Every dollar invested in national parks returns $10 to the U.S. economy. We need to continue to invest in our national parks and other public lands for future generations. http://on.doi.gov/1EbKRRk
