Macaws- Well into their eighties, American couple, Richard and Margot Frisius, moved to Costa Rica to retire in 1980. In doing so, they took on their life's major work--a conservation, breeding and rewilding program for endangered Macaws. Once a common sight, the great green and the scarlet Macaw are now endangered. They've suffered massive loss of habitat including the Almendro tree, on which their survival depends. Recycled House- Set in vast English park lands, Stanmer House was built in 1727, complete with its own church. It was the ancestral home of the Earls of Chichester, who played host to Queen Victoria and Sir Winston Churchill. Now the local council owns the mansion and its new neighbour, the striking Brighton Earthship, an eco-friendly building originally designed for the deserts of New Mexico. Tree rings In Argentina's Patagonia- There is a sense of another time. Stories Abound of the Nessie-like monster of lake Nahuel Huapi. And the ancient, majestic forest evokes thoughts of Tolkien's Middle-Earth. The slow-growing Alerce trees have been known to live for over three and a half thousand years and grow more than 50 metres high. Standing for centuries they could tell us a thing or two, and they do. Canned Hunting- Animals living in South Africa's National Parks are fortunate--they are protected. But not so the estimated 3,000 lions living in cages or trapped behind fences in captive breeding centres. For these animals there is no protection from the ultimate predatory animal. This is the world of canned hunting--where money speaks for itself, but an animal can't. Where the trust of a hand-reared lion is betrayed and the rule book is shredded. Kolyma River- Sadly, in today's world, many rivers are dying. But deep in Russia's harshest environment, Arctic Siberia, what was once known as 'the river of death' is now a lifeline for local people. Winding through the permafrost is the Kolyma River. Under Stalin, the Kolyma region was the centre of the Gulag labour camps, where one million people died. Norway Seed Vault- It's known as the doomsday vault, but hopefully that's a bit melodramatic. The Svalbard Global Seed Vault has however been built to withstand earthquakes, nuclear strikes and major climate change. It's a global seed vault, designed to be a fail-safe backup for the other 1,400 seed banks in the world, in case they are hit by disasters, natural or otherwise.
