That is an understatement. Such a study seems appropriate and useful, but timing and priorities are of the essence. There is enormous motivation, including the hope for personal financial reward, behind the drive to introduce genetically engineered crops rapidly and on a global scale. Given our very limited knowledge, it appears to be impossible to predict with a high degree of confidence the consequences of widespread introduction of genetically modified organisms, and particularly transgenics. These unpredictable consequences, many scientists believe, may be irreversible and possibly catastrophic.
Immediate action is needed.
I believe the precautionary principle should be applied now, broadly and rigorously, and that we should be extremely skeptical about claims of substantial equivalence. This certainly does not imply a hiatus in scientific investigation, but probably requires an immediate moratorium, and effective controls for the indefinite future, on release of genetically engineered organisms into the environment. Improving the quality and tone of the debate is important, but realistic and prudent risk assessment is critical to decisions on the application of transgenic biotechnology. I certainly need to understand more before I can be comfortable with the present rush toward global introduction of genetically modified crops. But satisfying the need for clear public understanding is not merely a personal wish.
