Ecologists are primarily concerned that polar bears may not be able to adapt to global warming because climate change is happening too rapidly for bears to adapt fast enough. As the Arctic warms and sea ice diminishes, polar bears are losing their primary habitat and hunting grounds, which are crucial for their survival. The pace of these changes often exceeds the ability of polar bears to adapt evolutionarily or behaviorally. Thus, the first option best captures the essence of the concerns regarding their adaptability to the rapid changes associated with climate change.
Why are many ecologists concerned that polar bears may not be able to adapt to global warming?
Because climate change is happening too rapidly for bears to adapt fast enough.
Their fur is too white to camouflage themselves from land prey.
There is too much competition from grizzly bears for them to compete for food sources.
