The Alarming Decline of Insect Populations: Causes and Implications.

Insect populations and biodiversity are declining globally due to increased land use, climate change, and invasive species. This trend threatens the stability of ecosystems, as fewer insects mean less pollination and pest control, and less food for insect-eating animals. Researchers suggest standardized techniques to monitor insect diversity and the creation of a network of interconnected nature reserves to allow species to migrate to cooler regions. Measures to reduce the dispersal of invasive species through global trade and tourism are also needed.
