答案 Climate Change You’ve probably heard that climate change is bad news for many animal species like polar bears. / Warmer temperatures mean less sea ice in the Arctic region. / And with less ice, there’s less room for polar bears to hunt. / And so their populations shrink. / But rising temperatures do not affect all animals in equally harmful ways. / For some animals, even for some bears, warming may be beneficial. / Take, for example, the grey bears. / Like pretty much all animals, they thrive when they have more food. / Warmer temperatures have resulted in them having easier access to food. / The more food they have, the fatter the bears get. / And the more fat they store, the better their chances of having healthy babies. / Baby bears born during warmer than normal years / were found to grow into larger and healthier adults. / Of course, for every species that may benefit from global warming, / many more may suffer and possibly go extinct.
