Insect Population Decline and Impact

Insect populations are rapidly declining, threatening global biodiversity and ecosystems. Insects, which make up 80% of species diversity, are crucial for energy transfer in food chains. A study shows 40% of insect species are declining, with a 2.5% annual biomass loss. Major causes include monoculture and global warming, affecting habitats and pollinators. The decline impacts everyone, but solutions like choosing organic produce and spreading awareness can help mitigate the crisis.
