Scientific Facts on Genetically Modified Crops
- Greenfacts.org, Nov. 15, 2005
We are regularly confronted with genetically modified foods, be it in the news or on our plates. In what way are GM crops different from conventional crops? What is known about their possible risks for human health or the environment?
This study is a faithful summary of the leading scientific consensus report produced by the FAO (Food & Agriculture Organization):

Conclusions 8.1: Agricultural biotechnology can be seen as both:
A scientific complement to conventional agriculture, aiding for instance plant breeding programs, and
- A dramatic departure from conventional agriculture, enabling transfer of genetic material between organisms that would not normally mix.
Agricultural biotechnology has international implications and may become increasingly important for developing countries. However, research has tended to focus on crops important to developed countries.
To date, countries where genetically modified crops have been introduced in fields, have reported no significant health damage or environmental harm. Moreover, farmers are using less pesticides or using less toxic ones, reducing harm to water supplies and workers' health, and allowing the return of beneficial insects to the fields.
Some of the concerns related to gene flow and pest resistance have been addressed by new techniques of genetic engineering.
However, the lack of observed negative effects does not mean that they cannot occur. Scientists call for a cautious case-by-case assessment of each product or process prior to its release in order to address legitimate safety concerns.
"Science cannot declare any technology completely risk free. Genetically engineered crops can reduce some environmental risks associated with conventional agriculture, but will also introduce new challenges that must be addressed. Society will have to decide when and where genetic engineering is safe enough." (FAO 2004)
