Precautionary Principle was formulated in the late 1960's
to stop progress where there was a potential risk to health

principle was intended to enable people to say "no", rather
than wait for the proof of danger to arrive - which may be
too late. The saying 'it is better to be safe than sorry'
has been legally translated via the precautionary principle.
precautionary principle, loosely speaking, means you can reject
things that are worrying. However it should not be used to
stop progress without significant reason.

there are threats of serious or irreversible damage lack of
full scientific certainty shall not be used as a reason for
postponing cost-effective measures to prevent environmental
