Today is the last day of American Wetlands Month, but don't let that bog you down. Take today to shine a spotlight on wetlands. Held throughout May, this national observance shines a spotlight on wetlands—some of the most productive ecosystems in the United States—and few places show their power quite like Everglades National Park.
