Environmentalists complain that there is little appetite among Europeans for genetically-modified foods, and that the safety of GM products has yet to be conclusively proven.
The fact of there being a market or not being a market is not anybodies concern except the people selling the goods. It would actually be beneficial to the environmentalists for markets to be opened up and the people selling the GM food to go bankrupt. If fact that would be what the environmentalists would want.
Now safety is a concern but not the environmentalists concern.
None of their reasons for not having GM food made and sold has any thing to do with the environment.
That is just odd.
