Galápagos: The great climatic seesaw
Season 7
Episode 708
The Galápagos Islands are significantly affected by climate changes. During El Niño, the islands receive more rain and land critters prosper, but the water is warm, endangering the lives of all marine creatures. During La Niña, rains are sparse, threatening terrestrial life, but the colder water brings bounty to aquatic animals. It's a never-ending race to survive from one extreme to the next.
