The South Arctic region is a vast area encompassing the southernmost parts of the Arctic, often referred to as the Subarctic. Some synonyms for this region include the Northern Boreal Zone, North American Taiga, and the High North. The Arctic Circle separates the South Arctic region from the North, and it is home to many unique plant and animal species, including polar bears, reindeer, and Arctic foxes. The region is also experiencing the effects of climate change, with rapidly melting sea ice and rising temperatures. Despite the challenges faced by the region, it remains a vital part of the world's ecosystem and a place of breathtaking natural beauty.
