Insects are essential for the proper functioning of all ecosystems. If policymakers don’t act now, we’re all in trouble
Most of us spend more time swatting away or avoiding wasps and moths than we do contemplating their importance to the web of life. But it is no exaggeration to say that the horrifying decline in the number of these creatures – the most widespread on Earth – is a barometer for the whole planet.
The new global scientific review into the perilous condition of our insects reports that more than 40% of insect species are threatened with extinction while the mass of insects is declining by 2.5% a year. This catastrophic decline is a direct cause of the existential threat to other animals, insects being at the bottom of the chain and the primary food source. Since 1970, 60% of mammals, birds, fish and reptiles have been wiped out.
