The United States banned Mexican avocados since 1914, due to fear of insect infestation and cheaper competition. However, in 1994, Mexico, Canada and the United States signed the North American Free Trade Agreement and soon the United States lifted the ban.
Before 1994, each american person consumed on average medium kilo of avocado, however until today they consume on average 3.2 kilos of avocado.
According to a 2016 study commissioned by a marketing group for buyers and producers of Mexican avocados, the supply chain of this fruit has also created about 19,000 jobs in the United States and has added more than $ 2200 million to the domestic product.
However it also has negative effects: Michoacán, the largest producer in the world, has paid a very high cost for its cultivation. For several years, the harvesting of the fruit has led to the deforestation of thousands of hectares of pine and oak forests.
Donald Trump has often ranted against NAFTA, calling it "the worst trade agreement ever signed." However, its focus on the loss of manufacturing jobs in the USA overlooks one of the long-term benefits of the treaty: the huge rise it has brought in agricultural trade and consumer satisfaction in all three countries.
