In GMO Myths and Truths, the authors attempt to cross this divide by taking a science-based, heavily referenced approach to dealing with claims for the benefits of GM foods.
On the basis of this research, they argue that a large body of scientific and other authoritative evidence demonstrates that most claims for benefits of GM foods are not true. On the contrary, they say, the evidence presented in their report indicates that GM crops:
Are laboratory-made, using technology that is totally different from natural breeding methods, and pose different risks from non-GM crops
Can be toxic, allergenic or less nutritious than their natural counterparts
Are not adequately regulated to ensure safety
Do not increase yield potential
Do not reduce pesticide use but increase it
Create serious problems for farmers, including herbicide-tolerant "superweeds", compromised soil quality, and increased disease susceptibility in crops
Have mixed economic effects
Harm soil quality, disrupt ecosystems, and reduce biodiversity
Do not offer effective solutions to climate change
Are as energy-hungry as any other chemically-farmed crops
Cannot solve the problem of world hunger but distract from its real causes - poverty, lack of access to food and, increasingly, lack of access to land to grow it on.
