Earthworms are in steep decline

If earthworms had feathers, wings or fur, or eyes that looked mournful – or eyes at all – perhaps they would fare better in the public’s affections. This is a clutch of species facing as much pressure from the ecological abuse of their habitats as any other – yet unlike, say, bees (which have their own UN day of celebration today), the decline of worms rarely makes the news. This is a shame. We need to talk more about worms. The health of our earth may depend on it.

Earthworms are not doing very well at the moment. This year, a scientific study found that 42% of fields surveyed by farmers were seriously deficient in earthworms; in some fields they were missing altogether. Particularly hard-hit were deep-burrowing worms, which are valuable in helping soil collect and store rainwater, but were absent from 16% of fields in the study.

The cause of these earthworm declines? The usual. An overstretched environment, creaking at its seams from the demands of modern Homo sapiens.

If the needs of earthworms are met, the land becomes, as if by magic, more fertile. Though modern farming practices are contributing to worms’ decline, farmers are, encouragingly, coming to understand that worms are allies, not enemies.

This is one of many reasons why we need to keep flying the flag for worms. Though we share very little with these organisms, we do share a rocky planet that is covered in a sprinkling of soil that they churn up for us, mixing up the nutrients upon which many millions of species depend.
