I've never understood why the precautionary principle gets so much circulation. Followed to its logical conclusion, it prohibits experimentation and technological progress, since nothing can really be proven safe before it's tried.

It might be apt to rephrase that into "Don't muck with things we can't fix."

When faced with ecosystem change, our ability to fix ills is extremely limited. Cane toads, kudzu, pythons in the Everglades, Asian carp, Emerald Ash Borers, and wolf depopulation have permanently changed habitats for the worse.

I'm fully aware of the tradeoffs in making hard choices, the sacrifices made for progress.

Any person who is unable (or unwilling) to do an honest accounting (pros vs cons, ROI) is unqualified to participate in any decision making process, especially on behalf of the rest of us.

Engineering and product design comes down to balancing needs, constraints. These shouldn't be foreign concepts for us geeks. And yet...
