Season 270 of the Ukulele - Songs by artists who have done benefit concerts. Jimmy Buffett has done a few of them - the most recent I'm aware of was in 2013 Kokua For The Phillipines where it was a benefit for victims of Typhoon Haiyan.
The song begins with lyrics in Tahitian:
Ia ora te natura
E mea arofa teie ao nei
Translated into English as:
"Nature lives (life to nature)
Have pity for the Earth (Love the Earth)"
One of my favorite songs of his.
