Why is the number of bees decreasing?

The decline in bee populations is primarily due to habitat loss, pesticide use, diseases, and climate change. Urbanization and agricultural expansion reduce the natural habitats available for bees, while pesticides can harm their health and disrupt their behaviors. Additionally, pathogens and parasites, such as the Varroa mite, have become significant threats to bee colonies. These factors combined create a challenging environment for bees to thrive.
