On the eighth annual "World Bee Day," around 400,000 bees in urban rooftop hives in Cologne, Germany, were busy at work making honey. They seemed oblivious to the threats that endanger their survival. Scientists and bee experts hope Tuesday's World Bee Day can raise awareness, reports the AP. For Matthias Roth, chairman of the Cologne Beekeepers Association, it's crucial to protect both honeybees—like the ones in his rooftop hives—and wild species. His organization has set up nesting boxes in the hopes of helping solitary bees, which don't form hives, but Roth fears that it's not enough. "We must take care of nature," Roth said Tuesday. "We have become far removed from nature, especially in cities, and we must take care of wild bees in particular."
Bees and other pollinators have been on the decline for years, and experts blame a combination of factors: insecticides, parasites, disease, climate change, and lack of a diverse food supply. A significant part of the human diet comes from plants pollinated by bees—not just honeybees, but hundreds of species of lesser-known wild bees, many of which are endangered. In 2018, the UN General Assembly sponsored the first "World Bee Day" to bring attention to the bees' plight. Steps as small as planting a pollinator garden or buying raw honey from local farmers were encouraged.
May 20 was chosen for "World Bee Day" to coincide with the birthday of Anton Jansa, an 18th-century pioneer in modern beekeeping techniques in his native Slovenia. In Germany, where bees contribute $2.3 billion in economic benefits, they're key to pollinating the iconic yellow rapeseed fields that dominate the countryside in the spring. (More bees stories.)
