The remaining 13 percent were crops that had both characteristics in the same plant. Although there are more than 70 varieties of crops approved for marketing in United States, sowings of scale in that country and at the global level during these ten years were soy, corn, canola and cotton, mainly to fatten cattle in rich countries. According to sources of the biotechnological industry itself, there are 22 countries that have approved commercial GM crops, but only 14 of these planted more than 50,000 hectares and are actually still just 4 – United States, Argentina, Canada and Brazil countries covering 90 percent of the global area planted with transgenic. Against the grain of cheerful industry data, statistics of the United States Department of agriculture (April 2006), show that transgenic crops produce less or equal than conventional crops, and the use of agrochemicals increased substantially in the past ten years. Seeds: key of the food chain in any other industry sector registers a corporate concentration so marked as in the case of transgenic seeds, where a single transnational company – Monsanto – controlled almost 90 percent of these seeds sown around the world. With the acquisition of the Mexican company Seminis in 2005 and the largest cotton worldwide – Delta & Pine Land – in 2006, Monsanto became the largest seed in general, not only transgenic. He dethroned as well to DuPont-Pioneer that for years it was the largest seed company in the globe, but also went on to dominate the global market for cotton seeds and managed to get into areas where it had no presence or was very weak, like fruits and vegetables. With the purchase of Seminis, Monsanto agreed to supply 3 thousand 500 varieties of seeds to producers of fruit and vegetables in 150 countries, controlling, inter alia, 34 per cent of the sale of seeds for production of chile, 31 percent of the beans, 38 percent of cucumbers, 29 percent of the peppers, 23 percent of 25 percent of onions and tomatoes.
