polar ecosystems

Polar ecosystems refer to the unique environments found at the Earth’s poles, specifically the Arctic and Antarctic regions. These areas are characterized by extreme cold, ice-covered landscapes, and prolonged periods of darkness or daylight. Flora and fauna here have adapted to harsh conditions; for instance, polar bears and seals thrive on ice, while phytoplankton serves as a fundamental food source in icy waters. These ecosystems are sensitive to climate change, which threatens their fragile balance, impacting both wildlife and indigenous human communities. Understanding polar ecosystems is crucial for addressing global environmental challenges.
