SciShow: Bears Have Babies While They’re Hibernating

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: Bears forgo many activities to conserve their energy in the winter when food is scarce, including eating, peeing, and pooping. There is one thing that they specifically DO do during the winter, though: give birth! But, giving birth during the harshest possible time of year seems like kind of a bad idea, so why do they do it?
