Quick Summary

The Antarctic Treaty System is a collection of international agreements that preserve Antarctica for peaceful purposes and scientific research. Signed in 1959 by 12 nations, the treaty established Antarctica as a demilitarized zone, forbidding military bases, weapons testing, and radioactive waste disposal. It encourages scientific investigation and the exchange of information.12

A significant addition is the Protocol on Environmental Protection (Madrid Protocol), which designates Antarctica as a natural reserve devoted to peace and science. This protocol bans mining and regulates all activities impacting the environment, including species introduction and human access. The treaty system does not deny or support territorial claims but prohibits new ones.312
