A tomato is a tomato, or that’s what it might seem like to grocery shoppers in Barcelona. But Karim, who currently oversees two hectares of organic gardens in Campíns, an area northeast of Barcelona located at the foot of the Montseny mountain range, knows otherwise. “We don’t know what we eat,” he tells us. “I used to work at other places dedicated to industrial farming, and they added a powder to tomatoes to force them to mature in a couple of days. There was a storeroom where we had to put on a special protection suit before entering [the greenhouses] because the tomatoes were sprayed with harmful products that could go directly to our bones.”
