Americans Love Avocados. It’s Killing Mexico’s Forests.

First the trucks arrived, carrying armed men toward the mist-shrouded mountaintop. Then the flames appeared, sweeping across a forest of towering pines and oaks.

After the fire laid waste to the forest last year, the trucks returned. This time, they carried the avocado plants taking root in the orchards scattered across the once tree-covered summit where townspeople used to forage for mushrooms.

“We never witnessed a blaze on this scale before,” said Maricela Baca Yépez, 46, a municipal official and lifelong resident of Patuán, a town nestled in the volcanic plateaus where Mexico’s Purépecha people have lived for centuries.

In western Mexico forests are being razed at a breakneck pace and while deforestation in places like the Amazon rainforest or Borneo is driven by cattle ranching, gold mining and palm oil farms, in this hot spot, it is fueled by the voracious appetite in the United States for avocados.

A combination of interests, including criminal gangs, landowners, corrupt local officials and community leaders, are involved in clearing forests for avocado orchards, in some cases illegally seizing privately owned land. Virtually all the deforestation for avocados in the last two decades may have violated Mexican law, which prohibits “land-use change” without government authorization.
