New peer-reviewed paper draws attention to environmental problems associated with GM crops and the gaps in our knowledge of their effects
A new scientific review (abstract below) below makes some interesting points on the environmental impacts and regulatory assessment of GM plants. Here are some quotes:
* “The current state of knowledge reveals that GM crops impart damaging impacts on the environment such as modification in crop pervasiveness or invasiveness, the emergence of herbicide and insecticide tolerance, transgene stacking and disturbed biodiversity.”
* “Recent claims of consensus over the safety of genetically modified organisms (GMOs) seem to be an artificial and misguided perpetuated construct... regardless of contradictory evidences published during last three decades which lead scientific community to reconsider that the debate on this topic isn’t ‘over’ yet.”
* “Current regulatory pathological and toxicological tests are confined on only one mammal and for 90 days which is insufficient and could not be generalized. So, toxicology studies should be prolonged to full life span of the test organism and other experimental mammals should also be considered for such tests.”
* “Safety studies involving GM plants produced as a result of ds-RNA mediated gene silencing should be conducted and after effects of administering GM foods having artificial siRNAs must be examined on a laboratory scale especially for their unintended effects on humans.”
* “Sub-lethal effects on nontarget species should be assessed for several successive generations
rather than single or two generations.”

Powerful scientific techniques have caused dramatic expansion of genetically modified crops leading to altered agricultural practices posing direct and indirect environmental implications. Despite the enhanced yield potential, risks and biosafety concerns associated with such GM crops are the fundamental issues to be addressed. An increasing interest can be noted among the researchers and policy makers in exploring unintended effects of transgenes associated with gene flow, flow of naked DNA, weediness and chemical toxicity. The current state of knowledge reveals that GM crops impart damaging impacts on the environment such as modification in crop pervasiveness or invasiveness, the emergence of herbicide and insecticide tolerance, transgene stacking and disturbed biodiversity, but these impacts require a more in-depth view and critical research so as to unveil further facts. Most of the reviewed scientific resources provide similar conclusions and currently there is an insufficient amount of data available and up until today, the consumption of GM plant products are safe for consumption to a greater extent with few exceptions. This paper updates the undesirable impacts of GM crops and their products on target and non-target species and attempts to shed light on the emerging challenges and threats associated with it. Underpinning research also realizes the influence of GM crops on a disturbance in biodiversity, development of resistance and evolution slightly resembles with the effects of non-GM cultivation. Future prospects are also discussed.
