ALICIA BAJA, MISIONES, ARGENTINA – NOVEMBER 2012: Lucas, who is 1 year and 10 months old, and his brother Gabriel in their home. Lucas was born with a malformation, and suffers from ichthyosis. Both his father Harnoldo and his mother Rosana Maria have spent their working lives cultivating of tobacco and other local crops such as corn and yerba mate. They use agrochemical products for the cultivation of their fields, following the guidelines set out by the cooperatives of large local producers, who require the use of such agrochemicals as a condition to the purchase of their crop. Among the agrochemicals required are glyphosate and 2.4 D, a product found in Agent Orange. The financial costs of these products always fall on small producers, who only retain 40% of the value of the crop, which is unilaterally fixed by the cooperatives of large producers.
