No one will deny that scientific research also has risks and engenders dangers. Decisions have to be taken on research projects without knowing in advance what the results will be (if it were otherwise there would be no point in starting). The dangers of such an enterprise are also obvious. They arise from the circumstance that in modern society knowledge, once it has found its way into the world, can be neither kept secret nor ignored by other function systems as soon as it becomes relevant in their context. This is particularly true for the economy because of the pressure of competition. It also holds for the political system in the military field, and for the whole area of intervention and protection policy. (…) Finally, there are risks inherent in scientific research itself, where, for example nuclear energy is in play or genetic engineering experiments are carried out.

Commercial cultivation of genetically modified (GM) crops has advanced in developing countries and is now widespread. The largest increase among developing nations has occurred in Brazil, where, until recently, national policies had restricted GM agriculture. However, since enactment of a new law in 2005 setting forth procedures for approving the planting and sale of GM crops, Brazil has become the leading exporter of GM soybeans, has GM crops growing on 9.4 million hectares, and now produces an estimated 10 percent of global GM crops, at last count.
