‘Better safe than
sorry’
Means that no
activity which ‘raises
threats of harm to
human health or the
environment’ should
proceed until proven
‘safe.’
Innocent until proven guilty
• industry may proceed if no one can find
species that will be directly affected
Misunderstood and Misrepresented
•Misunderstood, because precaution is so often
wrongly claimed to be unscientific or anti-
technology.
•Misrepresented, because a large part of the
resulting stigma can be a systematic – even
deliberate – effect of power!!
