The result of other very, very, very, very ignorant anti-GMO efforts are writ large: The unnecessary blinding of children because of a lack of access to Golden Rice, often described in terms with which I agree as a A Crime Against Humanity.
The anti-GMO movement is exactly and precisely equivalent to the anti-vaccine movement; the export of the anti-vaccine movement by ignorant first worlders to the third world has prevented the complete elimination of polio.
Genetic transfer is a normal and frequently observed feature of life on earth, it has been going back to the time when the highest living things on the planet were slime molds. Genetic engineering is of course a directed exploitation of the same thing, but in terms of its genome effects it is not particularly different than breeding.
Important environmental issues and outcomes that will be rendered even more difficult because of anti-GMO appeals to ignorance vary from things as little known as the restoration of the American Chestnut forest, to the manufacture of important and vital drugs to cure diseases like cancer, and the effort to face what is sure to be an international food crisis under the rapid conditions of climate change.
Ignorance kills people, or, as is the case with Golden Rice, maims them.
