The Insect Apocalypse Is Here

What does it mean for the rest of life on Earth?

Plummeting insect numbers 'threaten collapse of nature'



Why are insects in decline, and can we do anything about it?

How bad is it?
Extremely. By some measures, the biodiversity crisis is even deeper than that of climate change. Since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals. In the last 50 years alone, the populations of all mammals, birds, reptiles and fish have fallen by an average of 60%.

How about insects?
The new global review says it’s even worse for bugs, with the proportion of insect species declining being double that for vertebrates. The insect decline is at least a century old, but seems to have accelerated in recent decades.

Does that matter?
Yes. There are more than a million species of insect, compared with just 5,400 mammals, and they are the cornerstone of all terrestrial ecosystems. Without them, you get what scientists call a “bottom-up trophic cascade”, in which the knock-on effects of the insect collapse surge up through the food chain, wiping out higher animals. And without healthy ecosystems, there is no clean air and water.
