Plant Toxins: Duncan and Coca

plant toxins: Author Gustavo Duncan Duncan teaches political science at the private EAFIT University in Medellin, according to Deutsche Welle. The face of a young Pablo Escobar stares out from one of the books lining the shelves of his living room. I assume that this year's coca harvest will be the biggest of all time. Duncan may well be right about the harvest. One reason for this was that, as part of the peace negotiations with the FARC, the government refrained from the aerial spraying of coca fields with plant toxins. According to the United Nations, the area of cultivation of coca plants in Colombia doubled between 2013 and 2015. (news.financializer.com). As reported in the news.
