Conservation biologist Anne Sverdrup-Thygeson warns that the world's insect population is on the decline — which may have serious consequences for human beings and many other species.

Illustrator Lisa Hanawalt spoke with 'Fresh Air' producer Sam Briger about channeling anxiety into art. "Drawing is way of exorcising fears, and, for me, a way of controlling them," she says.
