What pesticides actually cost

Told soberly rather than fearfully. Synthetic inputs strip soil life, run off into water, harm bees and birds, and leave residue on our food. We name the cost honestly, and then we turn straight to the hopeful answer.

They strip the life out of soil

A meta-analysis of nearly 400 studies found pesticides harmed soil invertebrates such as earthworms in 71 percent of cases, through death, reduced reproduction and impaired growth. As these soil engineers decline, the ground compacts, absorbs less water and holds less carbon.

They run off into water

When soil structure degrades and rain cannot soak in, pesticides move with the runoff into streams and groundwater, carrying the harm downstream to water quality and aquatic life.

They harm bees and the wider web of life

Systemic insecticides reach the pollen and nectar that pollinators depend on, and are linked to the decline of the wild bees that a third of our food quietly relies upon.

They leave residue on food, and questions on health

In 2015 the World Health Organization’s cancer agency classified the herbicide glyphosate as probably carcinogenic to humans, citing strong evidence of genotoxicity. It is one example of why residue on the food we eat deserves sober attention, not panic.

The hopeful answer is already in your hands.

Every one of these costs has a clean alternative that works. The swap guide names the chemical and its natural replacement, one for one.
