It’s widely regarded as the most successful treaty in the world, and it was the first arms control agreement established during the Cold War. The Antarctic Treaty, which came into force in 1961, protects what is one of the most unspoilt places on earth, from mining, from military activity and allows only scientific exploration and peaceful pursuits. It was thanks to the treaty and research carried out in Antarctica that scientists identified a hole in the ozone layer in the 1980s, but it’s been most powerful as a symbol of what can be achieved to create peace between nations and give wilderness protection. So what has made this treaty so effective, and can it still hold up today in a world which is hungry for minerals and where an increasing number of states are seeking to project their technological and scientific prowess in Antarctica?
