Question 4 of 10
lisabon 2012 [21]

The atmosphere of Antarctica is left out of the Antarctic Treaty System. thus option B is correct.

<h3>What is the purpose of the Antarctic Treaty system?</h3>

They are: to foster international scientific cooperation in Antarctica; to put aside territorial sovereignty conflicts; to demilitarize Antarctica, establish it as a zone free from nuclear tests and the disposal of radioactive waste, and ensure that it is utilized only for peaceful purposes.

By mandating that Antarctica could only be used for peaceful purposes, the Antarctic Treaty System (ATS) protects Antarctic soil. Even while the ATS is a robust piece of legislation designed to safeguard scientists, visitors, and Antarctica's natural resources, it does not provide any protection for the region's atmosphere. "The Protocol on Environmental Protection to the Antarctic Treaty" is the piece of legislation that governs how Antarctica's atmosphere should be treated.
