”While the duty of preventing damage to the environment is based on a known the environment is based on a known
risk, the notion of precaution is based on lack of certainty.”(OECD 2001)lack of certainty. (OECD 2001)
as a consequence of the lack of long-term tests and major uncertainties in the risk assessement of
GMOs the approval of GMOs is not in line with the
precautionary principle as outlined in Directive2001/18 and Regulation 1829/2003
