What would happen if we ban GMOs?

Could you elaborate on the potential consequences of banning genetically modified organisms? Would such a ban have negative impacts on food production and sustainability? Would it limit the ability to combat hunger and malnutrition in certain regions? What would be the long-term effects on agricultural biodiversity and ecosystem resilience? Would it encourage more conventional farming practices that might have their own set of environmental challenges? And finally, how would such a ban align with the global demand for increased food production to support a growing population?
