Cows! Sometimes cute, frequently delicious. And for New Zealand, a critical engine of economic success. New Zeland occupies a rare patch of temperate agricultural land with abundant rainfall in the south Pacific. Good land and good rain mean good grass. Good grass makes happy cows. Happy cows? Lots of milk, and increasingly beef. New Zealand has one of the best geographies for low-cost, high-yield dairy and beef production on the planet. It also has a population roughly the same size as Costa Rica. The result? New Zealand is the largest dairy exporter in the world.
