[00:00.35]Three weeks on, [00:01.19]the shipwreck survivors [00:02.25]were in the heart of the Desolate Region, [00:04.96]and in deep despair. [00:07.22]In the boat's log, [00:08.01]one of the survivors wrote, [00:09.10]"The violence of raving thirst [00:11.51]has no parallel in the catalogue of human calamities." [00:15.64]They had almost run out of rations, [00:18.06]and despite being experienced sailors, [00:20.54]failed to catch a single fish. [00:23.48]But there are pockets of richness in the South Pacific. [00:26.91]One was well known to the crew of the Essex [00:29.25]and would have been in their reach, [00:30.97]but for the prevailing winds. [00:32.63]Lying over 700 miles off the coast of South America [00:35.63]are the Galapagos Islands. [00:38.45]Unlike the open ocean, [00:39.98]the seas surrounding these 100 or so islands are bursting with life, [00:43.88]with many creatures you wouldn't expect to find in tropical seas, [00:48.41]like these sea lions. [00:50.42]Despite sitting on the equator, [00:52.06]the waters around the Galapagos are cooled [00:54.61]by currents flowing all the way from Antarctica. [00:57.81]It is this that allows the Galapagos to be home [01:00.77]to the world's only tropical penguin. [01:04.22]Tropical fish live here, too. [01:06.95]Thanks to the nutrients carried by the cool current, [01:09.98]there is an abundance of life. [01:11.85]
