World Bee Day was held on May 20, 2025, in many countries. This event started to help people learn about the drop in the number of bees. The date was chosen because it is the birthday of Anton Janša. He was a beekeeping expert from Slovenia in the 1700s. In Cologne, Germany, about 400,000 bees were busy in rooftop hives. But scientists say bees are in danger. There are many reasons, like insect sprays, climate change, loss of places to live, and not enough flowers to eat from. More than 75% of the world’s food crops need bees. In Germany, bees help farms make about €2 billion each year.

Groups that care about the environment are doing more to help bees. Beekeepers are also helping both farm bees and wild bees. Matthias Roth is the leader of a beekeeping group in Cologne. He said they are using nesting boxes to help wild bees. But he thinks more help is needed. Experts say cities must have more green space for bees. Rooftop hives are a good step, but real change needs better laws and more learning. World Bee Day is a time to remember how important bees are to food and nature.
