When the price of something rises, the ecologist sees greed. The economist sees a message.
That difference is the whole argument β and it's why the environmental movement keeps reaching for the one tool guaranteed to make scarcity worse.
A price is not just a number on a thing. It's the most sophisticated information machine our species ever stumbled on. When a resource gets scarce β a mine floods, a war cuts a supply line β its price rises, and that single number travels the world carrying one command that requires no one to understand its cause: economize, find alternatives, this has become dear. Hayek won a Nobel for the insight. The knowledge needed to manage scarcity doesn't sit in any planner's head; it's scattered across millions of minds, and the price is the only thing that gathers it.
So a rising price isn't the problem. It's the solution arriving β the system noticing scarcityΒ beforeΒ the wall, and turning the whole ingenuity of the market toward avoiding it. It's why kerosene replaced whale oil before the last whale died, and why Ehrlich lost his bet to Simon on five metals that got cheaper, not scarcer.
There is one place the market genuinely fails: the externality β pollution, carbon β a cost dumped on third parties that never enters the price. That's real. But the fix isn't to abolish the price; it's toΒ completeΒ it. Tax the carbon so the signal tells the truth, then let the same machine economize, substitute, and innovate exactly as it does for any scarce input.
What you must not do is delete the message. Cap a price and you don't end the scarcity β you hide it, and the shortage arrives anyway, with queues and empty shelves. The 1970s gas lines happened in a country swimming in oil. Venezuela capped the price of food and got no food.
The deepest irony: whoever truly wants to conserve should be the price system's fiercest defender. It conserves automatically, in proportion to real scarcity, for a future no committee can see β and it can't be lobbied, doesn't stand for re-election, and corrects its own mistakes the moment they cost something.
The ecologist and I want the same world: one that doesn't squander its inheritance. We disagree only on the instrument. He reaches for the visible hand of control, which destroys the information it needs to work. I reach for the invisible one β the best friend the future ever had, if only we'd let it tell the truth and then listen.
