Climate changes may tip delicate balance in Patagonia
…At Puerto Williams, a Chilean naval base on the island of Navarino in the Beagle Channel, scientists from a number of countries and universities are studying biodiversity changes in some of the very lands that Charles Darwin trod 180 years ago in formulating his theory of natural selection. In the Omora Ethnobotanical Park, they have established a primitive outpost both to learn more about the delicate balance of life in this sub-Antarctic region as well as to teach visitors the importance of respecting natural forces.
