Galapagos: The Great Climatic Seesaw

The Galapagos Islands are especially affect by climate changes. During El Nino years, the islands receive more rain and land critters prosper, but the water is warm, endangering the life of all marine creatures. During La Nina, rains are sparse, threatening terrestrial life, but the colder water brings bounty to marine creatures. It's a never-ending race to survive from one climatic extreme to the next.
