Money can't tell help from harm, so it treats pollution as someone else's problem. Subtract harm before reward, and the incentive finally points the right way — no nagging required.

The root problemPicture a factory upstream and a town downstream. The factory earns money for what it makes; the pollution it sends down the river is real, but it lands on no one's ledger — the fish, the drinking water, the town's health. Economists call that an externality: a cost that's real but external to the price. Because money records only what's paid, the damage is invisible to the single number everyone optimizes. The factory profits; the river pays.
Multiply that by an entire economy and you get the strange result at the heart of our environmental trouble: a system that can wreck the very thing it depends on and still call it growth — because the wreckage never showed up in the math.
The one moveCopiosis fixes this with a single structural choice: harm is subtracted from benefit before any reward is calculated. Pollute a stream or burn through a scarce resource, and that harm counts against your reward. Restore a wetland or cut waste, and that good counts for it. The externality isn't taxed, regulated, or shamed from outside — it's brought inside the one number that decides what your work was worth.
Nothing else about the design has to change to make this happen. Once the measure is benefit-minus-harm, the environment stops being an afterthought and becomes part of the score.
Versus the usual fixesWe already have tools for environmental harm. They share one weakness: they fight the incentive from outside instead of changing it.
The consequenceOnce harm is priced into the reward itself, protecting the planet stops being an act of charity you can't quite afford and becomes the economically rational thing to do. The greenest way to work is also the best-rewarded way to work — not because anyone was ordered to care, but because the measurement finally points that direction. The person who cuts waste isn't a hero swimming upstream; they're just playing the game well.
In practiceWhen harm subtracts and lasting benefit outscores a one-off sale, everyday behavior tilts green on its own:
A new kind of jobHere's the part money struggles to reach: under benefit-minus-harm, repairing environmental damage is itself high-benefit work, so it's well-rewarded. Restoring a wetland, cleaning a bay, replanting a forest — today these depend on grants, charity, and goodwill, because there's no profit in a healthy ecosystem no one can bill for. In Copiosis the good they create is exactly what the measure is built to see. The planet, in effect, gains a workforce it can finally afford.
At every scaleBecause the measurement runs at every scale of society at once — from the neighborhood to the whole world — a choice that looks good locally but harms the wider system doesn't quietly slip through. Harm is still harm when you widen the circle, and the wider circle is always part of the reckoning. It's the opposite of an economy that books a local profit and exports the damage over the horizon.
