Foreword / Howard Ris -- Introduction -- Understanding transgenic crops -- Environmental risks posed by transgenic crops -- Two risk scenarios : an experimental assessment -- International implications of commercialization -- Conclusions and recommendations -- Appendix: Experimental assessment of the replacement capacity of a population of plants. The authors argue that the commercialization and release of transgenic crops on millions of acres of farmland can pose serious and costly consequences. They propose a practical, feasible method of conducting precommercialization evaluations that will balance the needs of ecological safety with those of agriculture and business.--From publisher description.
