Lago Argentino is the largest and southernmost lake in Patagonia, Argentina, at the southernmost tip of the Andes. This lake is unique because of the spectacular glaciers that plunge directly into its waters, such as the Perito Moreno glacier and the Upsala glacier. It covers an area of 1,560 km² – more than three times the size of Lake Geneva – and plunges to a depth of 500 metres.
As a result of global warming, these fabulous glaciers are threatened with extinction before the end of the century.

In Namibia, in one of the oldest deserts on Earth, these fantastic red star-shaped dunes can reach 400 metres in height. They are among the highest dunes in the world, overlooking an ancient petrified desert that forms a bedrock of sandstone and salt. The problem is that this site is one of the most visited in southern Africa, and is threatened by over-tourism, since deserts are also fragile ecosystems…

This is Seoul, the city of crisp, clear mornings, 4ᵉ the world’s most populous metropolis. 27 million people live here, on the banks of the Han River, in a capital whose history goes back more than 2,000 years.
