Biossegurança ambiental de OGMs.

ABSTRACT: In 2005, there were 90 million hectares cultivated with GMOs by 8.5 million producers in 21 countries. In 2006, we commemorated 10 years of commercial production of GMOs. Currently there are 10 million farmers planting 100 million hectares. However, several points were raised concerning the environmental impact of GMOs: (1) risk of cultivated or wild hybrid become a harmful invasive species, (2) development of resistance by the massive use of technology, (3) possibility of vertical or horizontal gene flow, (4) adverse effect on non-target and beneficial species, (5) impacts on crop production systems. This article discusses the main results on those concerns. The data obtained so far show that the environmental impacts of GMOs ares similar to a non transgenic crops and are related to the incorrect management of culture than the use of a transgenic cultivar. Meanwhile, the concerns are relevant and should continue to be discussed in international forums and studied in researchers institutions to elucidate the controversial results. However, the results obtained so far show no scientific evidence of the impact of GMOs into the environment.
