The effects of climate change on polar bear populations have been a significant concern for researchers. As ice caps continue to melt, polar bears are facing challenges regarding their hunting grounds and overall survival. A recent study indicated that these changes in ice habitats have led to decreased access to seals, which are a primary food source for polar bears. Additionally, researchers noted that with the rise in global temperatures, polar bears are forced to swim longer distances to find food, which can result in exhaustion and lower birth rates.
