Explanation:

The Annex on Environmental Security to the Antarctic Treaty (also recognized as the Madrid Protocol) is the foundation of the Antarctic Treaty. The Treaty sets aside Antarctica as a natural refuge. It is a legally binding document that lays out guidelines and protocols for the conservation of the Antarctic climate. Across the whole of Antarctica there are only a few thousand people living on the continent during the peak summer period. The most populous Antarctic centre is McMurdo Base on Ross Island, south of New Zealand, operated by the United States. Long ago, Antarctica was a much warmer place, home to dinosaurs and lush plant life. Even before the dinosaurs roamed, an iguana-like Triassic reptile called the Antarctica home. Researchers announced the discovery of the reptile, dubbed Antarctanax shackletoni, this year. The climate and physical and biological properties of the continent and the surrounding ocean are closely coupled to other parts of the global environment by the ocean and the atmosphere. For example, the Antarctic ozone hole was one of the most significant scientific discoveries of the last century.  In the early 1990s, there were about 6,000 tourists visiting Antarctica each year.

hope this helped!
