A Moment with the Bees
A commercial beekeeper opens one of his 72,000 hives in Lost Hills, California. The bees at this site have been trucked from all over the West to pollinate fruit trees, a practice both critical to agriculture and stressful for bees. Honeybees pollinate plants that account for over a third of the world's food supply, but their population is rapidly declining due to factors like climate change and pesticide poisoning.
