Polar habitats, such as Arctic and Antarctic regions, are significant for global ecology as they play crucial roles in regulating the Earth's climate. These regions act as cooling zones, influencing ocean currents and atmospheric circulation patterns. Polar ice caps reflect sunlight, aiding in temperature control. They also serve as habitats for unique wildlife, such as polar bears and penguins, and contribute to biodiversity. The melting of polar ice due to climate change poses threats not only to local ecosystems but also to global ecological balance and sea-level stability.
