Michoacán, where about four in five of all avocados consumed in the United States are grown, is the most important avocado-producing region in the world, accounting for nearly a third of the global supply. This cultivation requires a huge quantity of land – much of it found beneath native pine forests – and an even more startling quantity of water. It is often said that it takes about 12 times as much water to grow an avocado as it does a tomato. Recently, competition for control of the avocado, and of the resources needed to produce it, has grown increasingly violent, often at the hands of cartels. A few years ago, in nearby Uruapan, the second-largest city in the state, 19 people were found hanging from an overpass, piled beneath a pedestrian bridge, or dumped on the roadside in various states of undress and dismemberment – a particularly gory incident that some experts believe emerged from cartel clashes over the multibillion-dollar trade.
