Polar expeditions are journeys undertaken to explore the extreme environments of the Arctic and Antarctic regions. These expeditions often involve scientific research, mapping uncharted territories, and studying wildlife and climate. Notable explorers, such as Roald Amundsen and Robert Peary, have contributed to our understanding of these harsh landscapes. These expeditions typically require specialized equipment and training due to the severe weather conditions and icy terrain. Researchers collect data on glaciers, sea ice, and polar ecosystems to better understand climate change and its impact on the planet. Such efforts are crucial for preserving these unique environments.
