Urgent new ‘roadmap to recovery’ could reverse insect apocalypse
The world must
eradicate pesticide use, prioritise nature-based farming methods and urgently
reduce water, light and noise pollution to save plummeting insect populations,
according to a new “roadmap to insect recovery” compiled by experts. The call to action by
more than 70 scientists from across the planet advocates immediate action on
human stress factors to insects which include habitat loss and fragmentation,
the climate crisis, pollution, over-harvesting and invasive species.

Phasing out synthetic
pesticides and fertilisers used in industrial farming and aggressive greenhouse
gas emission reductions are among a series of urgent “no-regret” solutions to reverse
what conservationists have called the “unnoticed
insect apocalypse”. Alongside these
measures, scientists must urgently establish which herbivores, detritivores,
parasitoids, predators and pollinators are priority species for conservation,
according to a new paper
published in Nature Ecology & Evolution. The animals are crucial to the
healthy functioning of ecosystems by recycling nutrients, serving as
pollinators and acting as food for other wildlife. The paper comes amid
repeated warnings about the threat of human-driven insect extinction causing a
“catastrophic collapse of nature’s ecosystems”, with more than 40% of insect
species declining and a third endangered, according to the first
worldwide scientific review, published in February 2019...
