Thank you so much for asking, because it is in the preamble. In my view, if we look at how risk management has been failing to meet an appropriate pace, we are not meeting the precautionary principle.
In many cases there's a duty to act to prevent harm when evidence is mounting that a substance is harmful but there might still be some debate among scientists. We all know how long it took that debate about tobacco causing lung cancer to go on, and there are reasons for that.
The precautionary principle is what we do to protect human health while those conversations that are sometimes political conversations about the data are happening. Currently, because we take so long to make decisions to get rid of some of these substances, we're not actually applying the precautionary principle.
