Experts predict that polar bears will disappear by the year 2050. This prediction is based on various factors such as climate change and the loss of their natural habitat. The melting of polar ice caps due to global warming is causing a decline in the availability of sea ice, which is crucial for polar bears' hunting and breeding. As their main food source, seals, becomes scarce, polar bears are facing challenges in finding enough food to survive. Additionally, the loss of sea ice also leads to increased human-polar bear conflicts as bears are forced to venture into human settlements in search of food. These factors contribute to the prediction that polar bears will disappear by 2050.
