"People have to realize this is the only planet we have and we are making it filthy," Nash declared during the event.  "We have to save the planet and we have to do it for these kids."  He also performed a rendition of his classic Crosby, Stills & Nash hit "Teach Your Children."

The singer/songwriter famously displayed his concern for marine life in his 1975 Crosby & Nash tune "The Wind in the Water," which drew attention to the dwindling population of whales on the planet.

Graham and the rest of CSN currently are on a short break from their expansive U.S. tour, which gets under way again on Friday in Nashville.
