The term 'Polar' refers to the regions of the Earth surrounding the North and South Poles, characterized by extreme cold, ice, and unique ecosystems. These areas, including the Arctic and Antarctic, are home to specialized wildlife such as polar bears and penguins, which have adapted to survive in harsh conditions. Polar regions play a crucial role in regulating the Earth's climate and are sensitive indicators of climate change. Melting ice caps and shifting ecosystems in these areas can have far-reaching effects on global weather patterns and sea levels, making them vital for environmental studies.
