Liberia, Costa Rica

Sailing down Costa Rica’s Tempisque River on an eco-tour, I watched a crocodile devour a brown bass with one gulp. It took only a few seconds. The croc’s head emerged from the muddy waters near the bank with the footlong fish writhing in its jaws. He crunched it a couple of times with razor-sharp teeth and then, with just the slightest flip of his snout, swallowed the fish whole. Never saw that before.

These days, visitors can still see amazing biodiversity all over Costa Rica  more than 25 percent of the country is protected area  thanks to a unique system it set up to preserve its cornucopia of plants and animals. Many countries could learn a lot from this system.

More than any nation I’ve ever visited, Costa Rica is insisting that economic growth and environmentalism work together. It has created a holistic strategy to think about growth, one that demands that everything gets counted. So if a chemical factory sells tons of fertilizer but pollutes a river  or a farm sells bananas but destroys a carbon-absorbing and species-preserving forest  this is not honest growth. You have to pay for using nature. It is called “payment for environmental services”  nobody gets to treat climate, water, coral, fish and forests as free anymore.

The process began in the 1990s when Costa Rica, which sits at the intersection of two continents and two oceans, came to fully appreciate its incredible bounty of biodiversity  and that its economic future lay in protecting it. So it did something no country has ever done: It put energy, environment, mines and water all under one minister.
