Galapagos – Forces Of Change (BBC HD Documentary)
A land of fire set astride the equator and exposed to powerful forces of nature. This concluding episode reveals how, through time and isolation, the local animals and plants have evolved the most surprising ways to cope with the profound geological and climatic forces affecting them. Land iguanas are forced to climb to the summit of the harshest and most volcanically active of all the Galapagos islands to lay their eggs in the few pockets of warm, soft soil that exist here. Fur seals have learned to seek daytime shelter from the equatorial sun in magical undersea lava grottos. The most bizarre collection of plankton rise from the abyss in the middle of the night on currents welling up from deep beneath the flanks of Galapagos. And comical blue footed boobies have a flexible breeding season, reacting fast when the ocean currents are at their richest. Against a backdrop of smouldering volcanoes, brittle lava fields, fields of giant cactus and wave pounded shores, witness blue footed boobies plunge diving in to treacherous waters, sea lions surfing, the beautiful courtship dance of the waved albatross, Darwin’s finches as crafty tool users and hawks hunting marine iguanas. Galapagos is unlike any other place on Earth. The archipelago is made up of thirteen main islands, they sit astride the equator, almost a thousand kilometres off the coast of South America, and are connected directly to the heart of the planet. The product of a volcanic hotspot, from the moment they are born, the islands are carried on a remarkable millenia long journey before sinking back beneath the waves. The Galapagos islands are a fascinating microcosm of our planet and home to some of the most astonishing creatures found anywhere on Earth: iguanas swim the sea like dragons, short eared owls stalk petrels by day and 500 pound giant tortoises bellow over lava fields. One thousand kilometres due west of Ecuador, where four major ocean currents unite, vast undersea volcanoes break the surface of the Pacific Ocean. Early explorers described these otherworldly islands as „Las Encantadas“ „the Enchanted Islands“. In time they became known as Galapagos, the islands of the Tortoises. Darwin described them as a „world within itself“. Using spectacular HiDefinition cinematography from land, sea and air, and blending dramatic landscapes with intimate animal behaviour, drama reconstruction and stunning satellite imagery, this ambitious series presents the most complete portrait ever of these fascinating islands. Galapagos reveals how wildlife has found the most enterprising ways to get to grips with this restless volcanic outpost, why these islands are such a fascinating showcase for evolution, and the profound forces that influence the delicate balance of life.
