Ban Roundup tolerant GM crops
These latest studies confirm a wealth of evidence on the toxicities of glyphosate and Roundup formulations  (Glyphosate Toxic & Roundup Worse , SiS 26), and pinpoint the different sites of action, all of which result in cell death. Epidemiological studies have previously linked glyphosate to spontaneous abortions, non-Hodgkin lymphoma, and multiple myeloma. Laboratory studies showed that glyphosate inhibits transcription in sea urchin eggs and delays development. Brief exposures to glyphosate in rats caused liver damage, and adding the surfactant in Roundup had a synergistic effect, causing greater liver damage. Roundup was also found to be much more lethal to frogs than to weeds, and could have contributed to the global demise of amphibians within the past decades  (Roundup Kills Frogs, SiS 26).
We have called for a new regulatory review on glyphosate and Roundup in 2005 . There is a now a strong case for restricting, if not phasing out glyphosate and Roundup; in the first instance, by banning the release of Roundup tolerant GM crops worldwide. For the same reason, no further Roundup tolerant GM crops should be approved for commercial release.
