My understanding of the precautionary principle.... I think it was set out in the 1992 Earth Summit. It's contained in Agenda 21. It's contained in the Rio principles. I think there are different operational definitions for precautionary principle. I think one that's emerging now from an operational sense is to try to anticipate various levels of risk and to attempt to mitigate those risks prior to their opening into full-blown problems.
I'd be glad, sir, to follow this discussion, but as a first observation, that would be my answer.
