List just a few of the things environmental and health advocacy groups would have banned on the "precautionary principle," if only they'd had the chance:
Fire: too hot, hazardous, and burn-y

The wheel: dramatically increased risk of vehicle accidents

Electricity: can cause electrocution; creates obesity in people who sit too long in front of TV sets

The internal combustion engine: burns potentially planet-destroying fossil fuels.

The internet: might be used to disseminate dangerous information casting doubts on Man-Made Global Warming and/or pouring scorn/mockery on well-intentioned environmental and health advocacy groups thus impeding their noble battle to make the world entirely safe for everyone.

Psalms 118:8 It is better to trust in the LORD than to put confidence in man.
