Question

Quizplus · Accepted Answer

The decline of polar bears and global warming are both likely caused by a third variable, such as the increase in greenhouse gas emissions from human activities. Polar bears depend on sea ice for hunting and as the ice melts due to warming temperatures, it becomes more difficult for them to find food and survive. This decline in polar bear populations could be a sign of the larger impact of global warming on wildlife and ecosystems.
