Bee preservationist Michael J. Thiele, 54, holds a bee near a nest habitat in Sebastopol, California, September 6, 2019. Thiele estimates that he has "midwifed" billions of bees by building traditional nest habitats that attract bees from within the local watershed through swarming, which increases the bee population exponentially.
