In the last 30 years, we have lost about a quarter of our land-dwelling insects. The decline rate is just below 1 percent with variations at different places. Nick Haddad, Michigan State University butterfly expert says, “Ongoing decline on land at this rate will be catastrophic for ecological systems and humans.”
Not only butterflies that add to the beauty of our world and bees that are important for the food chain, but also bugs are seen to decline at an alarming rate. Insects which are natural enemies of pests, and also function as pollinators and decomposers can cause critical damage to the functioning of Earth’s ecosystems, due to the radical decline.
