Antarctica Day was established by the Foundation for the Good Governance of International Spaces (Our Spaces) as a way to celebrate the continuation of the Antarctic Treaty, which was signed on 1 December 1959.
The Antarctic Treaty set aside 10% of the planet “forever to be used exclusively for peaceful purposes in the interest of mankind”. You can find out more about the treaty and about Antarctica itself, from the Our Spaces Antarctica Day web page. There is also a teaching resources page.
