Cold environments are regions where temperatures consistently remain low, often below freezing. These areas can include places like the Arctic, Antarctica, and high mountain ranges. The climate is characterized by long, harsh winters and short, cool summers, with snowfall being common. In cold environments, ecosystems are adapted to survive extreme conditions. Flora and fauna, such as polar bears, penguins, and evergreen trees, have special adaptations to cope with the cold, like thick fur or blubber for insulation. These adaptations help them thrive despite the challenges posed by low temperatures and limited food availability.
