Threats to insects and conservation

Threats to insects and conservation: insect populations are declining worldwide. Causes include habitat loss, pesticide use, light pollution disrupting nocturnal insects, and climate change. Pollinator decline threatens food production. What children can do: plant pollinator-friendly gardens, reduce pesticide use, participate in citizen science like the Big Butterfly Count.
