While polar bears may not be mating with grizzlies to save themselves from climate change, scientists might turn to grizzlies if the need is dire. In the event that polar bear numbers decline catastrophically, scientists may freeze their sperm and eggs and use female grizzly bears as surrogate mothers. However, this is not likely to happen in the next several decades, since other conservation methods will surely be tried first. But can you imagine the female grizzly’s surprise when she sees her polar bear cubs? Hopefully, they can still learn how to be polar bears, if there’s any ice left.
30. Future surrogate mothers?
