Yield Problems


New Report Challenges GM Industry Myths
Farming Online, 19 June 2012

"The report GMO Myths and Truths is a detailed study covering everything from the genetic engineering technique through to an analysis of the benefits of GM foods and crops. The report is heavily referenced, allowing the reader to determine the validity of the authors’ conclusions. The section on GM crops’ impact on the farm and environment seriously questions the benefits of growing these crops, citing examples of increased pesticide use, pest resistance, inconclusive yield benefits and their value in feeding the worlds increasing population..... weighing in at over 120 pages ... it’s not the weight that makes for uncomfortable reading but the detailed critique of many of the supposed benefits of GM technology and the fact that these have all been brought together in one report. What makes it even more difficult to ignore is the credentials of the authors concerned, these are not your light-weight anti-everything tree huggers but acclaimed scientists. This should open up the debate at a high level on the benefits of GM crops and be essential reading not just for policy makers. The questions raised in this report are too numerous and serious to be simply disregarded."
