Why We Need Insects / Illustrator Lisa Hanawalt

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. Sverdrup-Thygeson talks about eating insects for protein, the ripple effect of insect species dying off, and how cockroaches might save your life. Her book is 'Buzz, Sting, Bite.'

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. Hanawalt's the creator of the Netflix animated series 'Tuca & Bertie' and creative designer of 'BoJack Horseman.'
