When lead was added to petrol it made cars more powerful and was, its advocates said, a 鈥済ift鈥. But lead is a gift which poisons people; something known as long ago as Roman times

In the 1920s lead was added to petrol. It made cars more powerful and was, according to its advocates, a 鈥済ift鈥. But lead is a gift which poisons people; something figured out as long ago as Roman times. There鈥檚 some evidence that as countries get richer, they tend initially to get dirtier and later clean up. Economists call this the 鈥渆nvironmental Kuznets curve鈥. It took the United States until the 1970s to tax lead in petrol, then finally ban it, as the country moved down the far side of the environmental Kuznets curve. But as Tim Harford explains in this astonishing story, the consequences of the Kuznets curve aren鈥檛 always only economic.
