Polar coasts are the shorelines found in the Arctic and Antarctic regions, characterized by extreme cold and unique ecosystems. These areas are often covered in ice, with glaciers and icebergs shaping the landscape. The coastal environment supports various wildlife, including seals, penguins, and polar bears, which rely on the sea for food and habitat. The polar coasts are also influenced by climate change, leading to melting ice and rising sea levels. This affects not only the local ecosystems but also global weather patterns. Scientists study these regions to understand the impacts of climate change and to protect the fragile habitats found there.
