In the mid-1990s, researchers at the Swiss Federal Institute of Technology completed a decade of work on a modified strain of rice. They called it Golden Rice. By inserting two genes—one from maize, one from a soil bacterium—they engineered a grain that produces beta-carotene in its edible portion. The modification was elegant and the need was urgent: Vitamin A deficiency affects roughly 250 million children worldwide, causing between 250,000 and 500,000 to go blind every year, half of whom die within twelve months of losing their sight.
Golden Rice worked. It was safe. Independent testing confirmed both facts repeatedly over two decades.
It still isn’t widely deployed because of opposition.
Regulatory bodies across Asia, bowing to organized opposition from environmental groups invoking the precautionary principle, (PP) delayed, restricted, and in many cases blocked the very technology that could have ended a preventable catastrophe. The Philippines, one of the countries where Golden Rice was closest to approval, saw its field trials destroyed by activists in 2013. A 2019 analysis in Nature Biotechnology calculated that the delay in Golden Rice deployment in India alone cost 1.4 million life-years annually.
That is what the precautionary principle does when applied with sufficient conviction.
Not saving lives. Taking them.
Consider that between roughly 1870 and 1960, Western civilization ran a ninety-year experiment in what happens when builders build without requiring proof that nothing will go wrong.
The results were spectacular!
Electricity went from laboratory curiosity to universal infrastructure in forty years. Internal combustion remade transportation in a generation. Antibiotics collapsed mortality curves for bacterial infection so sharply that the graph looks like a cliff. Aviation progressed from Kitty Hawk to the sound barrier in forty-five years. Nuclear fission moved from theoretical prediction to operational power plant in a decade. The transistor, discovered in 1947, made modern computing possible within fifteen years.
None of these technologies were safe in any meaningful precautionary sense when deployed. Electrical fires were common. Early cars killed their drivers without seatbelts, airbags, or crash standards. Antibiotic dosing required enormous experimentation on human patients. Aviation accidents were frequent enough to be unremarkable. Nuclear technology was developed in explicit awareness that it could produce civilization-ending weapons.
The risks were real. Builders built anyway—because the calculation was obvious. The upside was transformative and the downside, while genuine, was manageable through the actual mechanism of progress: deploy, observe, correct, improve. Not predict-all-harms-first. Not prove-zero-risk-before-proceeding. Build it. Watch what happens. Fix what breaks.
That ninety-year period produced more improvement in human lifespan, material welfare, and physical capability than the preceding ten thousand years combined. Not because risk was absent—because risk was treated as a problem to solve rather than a signal to stop.
