Today, genetically modified seeds have transformed agriculture in an industry. For FAO, GM food should be taken with caution. There has been no verifiable reports that generate a hazard, explains Jose Maria Sumpsi, Assistant Director-general of this organization. On the contrary, are some social and environmental benefits because farmers have to use fewer pesticides and they are replacing toxic chemicals with less harmful ones, argues. However, there are many critical voices to the use of transgenic seeds. With the excuse of helping the development of the planet, a small group of companies control seeds and patents have the key of the food chain, warn from alternative Latinoamericana. Monsanto, Du Pont, Pioner Hi-Brend, Daw Agro Sciences and Syngenta are four corporations that have in their hands the transgenic seeds. A farmer who buys any of these companies a seed with modified genes have to sign a commitment which cannot stay with second generation seeds. Thus, you will have to buy back the seeds for the next harvest. Farmers depend on these multinationals and price who would like to seed. Organizations like Greenpeace warn of the harmful effects that these modified food can have on health. More serious allergies, resistance to antibiotics, some of these negative effects are decreased ability of...

Agriculture is part of the agricultural sector, which derives all economic activities that are generated from the exploitation of the activity of agriculture through the various works carried out on the ground and of resources that generate from such activity, which may occur both naturally or through the intervention of man. Among the resources that can be given through agriculture, are: cereals, fruits, vegetables, pastures and another large amount of vegetables. In defining the content of agriculture, we can say that such activity includes various human actions that seek to modify an environment or natural environment, with the idea of making that field is more suitable so that optimum results can give in sowings.
