@techtuv: Bears are strong and dangerous animals, with species such as the grizzly bear, polar bear, and black bear living in different regions, each adapted to its specific environment. When encountering a bear in the wild, it is important to stay calm, avoid sudden movements, and quietly move away. Bears usually avoid humans, but they can become dangerous when protecting their young. Therefore, it is recommended to speak loudly in areas where bears are present and to carry bear spray as a precaution.
