Avocados are imported because they are not grown in North America or the United Kingdom. The more distant a food is from its source, the greater its impact.
They're typically grown in regions with limited access to clean water, despite the fact that they use twice as much water as oranges to grow.
Avocados require a lot of water, aggravating Mexico and California's droughts and heatwaves, making it harder to grow, leading to more deforestation, etc.
Farmers in Mexico are expanding their operations to meet rising consumer demand, leading to forest clearance and increased emissions of greenhouse gases.
Many big stores in the UK get their avocados from Petorca, Chile, which has had its water rights violated.
They are said to have built illegal pipes that bring water from rivers to fields to water them. Villagers say that because of this, there is a drought in the area.
More than a third of the avocados in the world are grown in Mexico, which is the largest producer in the world. Still, at what cost?
Cartels and gangs are fighting for control of the valuable avocado market in Michoacán, Mexico.
A gang called La Familia Michoacana is said to have thrown five opponents' heads onto sand in the town of Uruapan.
Multiple news outlets have reported that Mexican avocado farmers are unhappy with their profits and the risk of gang violence.
