Why talk about GM crops?
• Use is common, particularly in the U.S.
• 75 million acres planted in the U.S. in 2000
(Colorado State University 2004)
• 5 Million farmers grow GM crops (Perry 2003)
• Varying opinions regarding GM crops among
the world‟s governments
• Stigma attached to GM crops among the
What are GM crops?
• Plants which have been genetically altered to
express a desirable trait (Perry 2003)
• Herbicide resistance
• Virus resistance
• Environmental Tolerance
• Increased nutritional value
How are GM crops made?
• Most common method is by using
Agrobacterium tumefaciens (CSU 2000)
• Soil bacteria containing a tumor inducing (Ti)
• Isolate the gene containing the desirable trait
• Insert this gene into the Ti plasmid of
• Remove the tumor inducing genes of the
plasmid, and infect the plant cells
• Regenerate transformed cells into viable plants
Proposed benefits of GM crops
• Increased economic profits for the farmer
• Lower prices for the consumer
• Reduced dependence on chemical
fertilizers and insecticides (Gray 2002)
• Potentially decreased environmental
restriction (Chrisafis 2001)
• Potentially increased nutritional benefit
(CSU 2000, Coghlan 2005)
Potential dangers of GM crops
• Health concerns
• Contamination of organic populations
• GM crops can be very difficult to contain or
eradicate (Peterson et al 2000)
• Exploitation of third-world farmers by
American biotech companies (Peterson et al
A Biblical Perspective
• It is important to recognize the intrinsic value
of the environment as God‟s handiwork (Vautin)
• We should choose what is best for all of
humanity, rather than a few American
• Biotech companies should use extreme caution,
performing enough research to become as
certain as possible that the product does not
harm those who consume it.
• Right approach to GM crops is one that is
• We will need to find a way to increase food output in
• More food will not be sufficient without addressing
the political and economic issues
• Research should be allowed and encouraged to
continue to address safety and health concerns
