Iceland's Eyjafjallajokull volcano erupted April 14, 2010, spewing aircraft-harming ash over most of Europe. It could cause Katla, its neighboring, larger volcano to erupt.

The tropical rain forests of the world are home to nearly half the animal species on earth - an estimated five million different life forms. More than 100 inches of rainfall each year sustain this lush environment, where some of the most fascinating examples of natural adaptation can be found. Journey to the dense rain forests of Costa Rica and watch as leaf-cutting ants carry sections of leaves many times their weight to underground fungus gardens, a basilisk lizard walks on water, and howler monkeys bask in the sun. Fascinating and thought-provoking, this film is an eloquent warning of the natural wonders we stand to lose on a world scale if human encroachment of the world's rain forests continues.

As he hikes and paddles through the gorge, he explains the layers of rock, discovers animals that survive in this harsh landscape, and shows the petroglyphs of the Native Americans, for whom this fantastic world of red stone has always held spiritual significance.
