GMO? OMG!
Scientific method
The French study about tumour growth as a result of a diet of GMO maize ( or corn) as well as consuming various levels of ther herbicide Roundup® versus a control group that was fed non GMO maize has provoked many reactions in the press and governments.
This study can be considered a case study for looking at the scientific method along with the benefits and dangers of GMO which is studied in topic 4.4 Genetic Engineering & Biotechnology. Students should read the various positions some of which are provided here to assess the situation of GMO.
In the UK, the NHS engaged an analytical group, Bazian, which presents a review of the study as well as objective criticisms of the experimental design.
NewScientist produced a summary which declares the French scientists did not provide standard deviations in their results. Students should understand the importance of the standard deviation from their studies in topic 1 Statistical Analysis.
Both of the above articles provide information about supporters of the study -CRII GEN - Committee for Research and Independent Information on Genetic Engineering which is "an independent non-profit organization of scientific counter-expertise to study GMOs, pesticides and impacts of pollutants on health and environment, and to develop non polluting alternatives."[1]
Monsanto, which produces the herbicide Roundup and the GMO maize which is tolerant to the herbicide, of course has produced a statement about the research.
Greenpeace has not released a declaration about this recent study as this is written, but they do have a strong position about GMO's and have a statement about a study made in 2007.
The UN FAO (Food and Agriculture Organisation) produced a position paper in 2003 about the dangers of GMO's
How to use this information in classes:
Provide a variety of resources for students to read and study in order to produce arguments for the benefits and potentially harmful effects of GMO.
Set up a debate as groups of students represent various stakeholders in the GMO discussion.
- food producers / farmers
- agrobusiness genetic scientists who produce GMO's
- Greenpeace or other environmental action organisation
- governmental agency officials such as for Food and Drug Administration (or equivalent for your location)
- typical citizen or voter
- independent genetic scientist
Students could select their stakeholder group or be assigned to ensure equal sized groups. Each group should prepare their positions whether they agree with that position or not- the point is to develop the thinking skills and the evaluative skills of the evidence.
