A Couple Dropped 12,000 Tons of Orange Peels on Dead Land — Then Government Did Unbelievable

In 1996, ecologists Daniel Janzen and Winnie Hallwachs made an unusual proposal: dump 12,000 tons of orange peels on severely degraded land in Costa Rica. The couple, both ecologists and longtime researchers and technical advisers to the Área de Conservación Guanacaste (ACG), believed that what looked like waste could help restore an exhausted ecosystem. What happened next was unexpected. The orange peels began breaking down, enriching the soil and creating conditions for vegetation to return. But the story took another turn when the government stepped in and the project was suddenly stopped. Decades later, researchers returned to the site — and the difference was difficult to ignore. This is the story of one of the strangest ecological restoration experiments ever attempted, and how thousands of tons of food waste helped transform land that had once been considered nearly useless.
