Why is GMO banned in Europe?

Could you please elaborate on the reasons why Genetically Modified Organisms (GMOs) are prohibited in Europe? Is it due to concerns about potential health risks or environmental impact? Or is it more of a political decision based on consumer preferences and public opinion? Additionally, how does the ban affect agricultural production and food security in the region? Is there any scientific evidence that supports or refutes the ban? Lastly, what are the potential benefits and drawbacks of lifting the ban on GMOs in Europe?
