Critics of agricultural biotechnology have long maintained that the technology is unsuitable for small-scale farmers and harmful to the environment. But according to newly-released adoption rates, evidence is pointing in the opposite direction. In its latest report, Global Status of Commercialized Biotech/GM Crops: 2011, the International Service for the Acquisition of Agri-biotech Applications (ISAAA) shows that biotechnology crops now cover 160 million hectares worldwide. Of the 16.7 million people who grew transgenic crops in 2011, 15 million or 90% were small resource-poor farmers in developing countries.
