Apparently this isn’t a joke:
When an activity raises threats of harm to human health or the environment, precautionary measures should be taken even if some cause and effect relationships are not fully established scientifically.
In this context the proponent of an activity, rather than the public, should bear the burden of proof.
Ilya Somin and Jonathan Adler offer carefully reasoned arguments against the “precautionary principle”, but do we really need them? When someone questions the safety of an activity, the burden of proof is on the other side? That’s insane.
I say — and I’m not being facetious — that conferences on the precautionary principle endanger human health and the environment. Prove me wrong.
