The below survey is specific to the US but it is still very informative:
It would be interesting the survey results if the survey was replicated across European countries, to enable some cross-country comparisons. For example, the typical European is likely more averse to GM crops than Americans, but more likely to believe in human evolution. It would also be useful to add some granularity so we could see how the opinion of the average 'scientist' varies from scientists working in the field in question, such as geology specialists when it comes to the subject of fracking, climatology for global warming, and genetics for the GM issue. Afterall, scientists tend to be specialists in specific fields only.
