The Bradford Hill Criteria Applied to Climate Change & GMOs
If smoking causes lung cancer, we should try to stop people smoking, if greenhouse gas emissions are causing climate change, we should reduce them, if genetically modified organisms (GMOs) are hazardous, we should ban them. The problem for policy makers is that it is hard to be sure, or rather it is hard to be sure enough to convince a government to spend money or offend a powerful lobby. The Bradford Hill criteria can help in the difficult task of making decisions when the evidence, while strong, is not conclusive.
