Might do, maybe, let's panic anyway

Research undertaken for the World Wide Fund for Nature suggests that many chemicals in the environment persist in our blood for a considerable period of time - like PCBs, DDT etc.

But the quantities are absolutely tiny. So WWF resort to the line, "we don't know what they might do to us, so let's ban them". Well, while it is true that for every risk we've ever encountered, there will have been a period when we didn't know it was a risk, it is reasonable not to tailor our every action to the mere possibility of harm. How could anything useful ever get done?
