As you certainly know, repeated opinion polls show that a majority of European consumers are against genetic engineering of foods, demanding labeling of such food. Even in the US, a majority is now demanding labeling. They say it is an expression of ignorance or of irrational fears for a new technology or of irrational ideological or religious conceptions. However, this is not correct.
Genetic engineering is just a variety of breeding.
The truth is that genetic engineering is fundamentally different from breeding. Due to the artificial insertion of a foreign gene, unexpected harmful substances may appear. This is a scientific, experimentally verified fact. Genetically engineered foods have been carefully tested and found safe. The truth is that GE foods are not safe as presently tested.
