FORT MYERS, Fla. - In honor of Earth Day, Littleton Elementary School students dedicated a first-of-its-kind outdoor learning lab.

The five-acre outdoor facility was the brain child of the school's Environmental Science Club. The area also preserves the habitat of the gopher tortoises living on campus.

Earth Day was also the backdrop in Collier County, where officers from Collier County Fish and Wildlife released 150,000 large mouth bass into Lake Trafford. Recent algae blooms resulted in fish kills. The lake has been the site of FWC dredging projects designed to eliminate the "muck" that's thought to trigger the problematic blooms.

The lake will be stocked with an additional 50,000 fish next month.
