The "insect apocalypse" refers to the alarming global decline in insect populations, with over 40% of species at risk of extinction. This decline, driven by habitat loss, pesticide use, climate change, and pollution, poses significant threats to biodiversity and human well-being. Insects play vital roles as pollinators, decomposers, and prey for other species, and their loss disrupts ecosystems, affecting plants, animals, and essential processes like nutrient cycling. Addressing this crisis requires reducing pesticide use, restoring habitats, and adopting sustainable farming practices. Protecting insects is crucial for maintaining the health of ecosystems and ensuring food security and biodiversity for future generations.
