Bees are widely recognized for honey production, but their greater contribution lies in pollination, a process essential for global food production. While managed honeybees receive most attention, wild bees comprising over 20,000 species, play a critical and often underappreciated role in sustaining agricultural systems. These species exhibit diverse foraging behaviors and plant associations, making them highly efficient pollinators for many crops. However, wild bee populations are declining due to multiple interacting pressures, including pesticide exposure, habitat loss, climate change, and emerging threats such as microplastics and artificial light. This article highlights the ecological and economic importance of wild bees, outlines the major drivers of their decline, and discusses practical conservation strategies. Protecting wild bees is not only a biodiversity concern but also essential for maintaining food security and nutritional quality worldwide.
