President-elect Donald Trump's proposed tariffs on Mexico and Canada could significantly impact the avocado industry, as 90% of the avocados consumed in the U.S. are imported from Mexico. The tariffs could lead to higher avocado prices at the grocery store, although it's unclear by how much. The avocado industry already faces challenges such as climate change, water usage, deforestation, and extortion from criminal gangs in Mexico. The proposed tariffs, being unpredictable, present a unique challenge for the industry as it is difficult for the supply chain to adjust to policy changes.
