Insects serve an essential role in the ecosystem. Some insects aid in pollination that helps plants reproduce. Some insects also eat smaller insects that prevent their overpopulation. This is the reason why conservators and environmental advocates have been working hard to protect insects from its rapid decline.
Nearly half of all insect species worldwide are in rapid decline, and one-third of them are at risk of officially disappearing in their natural ecosystems.
A study has suggested that the world has to warn of the massive consequences that this decline presents in crop pollination and natural food chains.
“Unless we change our way of producing food, insects as a whole will go down the path of extinction in a few decades,” concluded the peer-reviewed study, which is set for publication in April.
The recent decline in bugs that fly, crawl, burrow and skitter across still water are the species that the study identifies to be at risk of “mass extinction.”
“We are witnessing the largest extinction event on Earth since the late Permian and Cretaceous periods,” the authors noted.
Francisco Sanchez-Bayo of the University of Sydney and Kris Wyckhuys of the University of Queensland in Australia said that the researchers have estimated that the global insect population is in decline at 41%, twice as high as that of vertebrates.
Additionally, scientist warns that this ratio is growing by 1% annually.
“Only decisive action can avert a catastrophic collapse of nature’s ecosystems,” researchers warned.
Restoring wilderness areas and reduction in pesticide use, as well as decisive policy, are most likely the best way to mitigate the population decline of insects. /apr
