Lessons from the Oil Spill

It looks like the Deepwater Horizon oil spill may finally be finished, as the cap on the well appears to be holding and the relief well will be completed in the near future.  What are some things we have learned?

1)  There is a lot of oil in the earth.  Lots.  Enough so that millions of gallons can pour from a broken well for days and days and it doesn't affect the supply.  This well was going to be abandoned by BP and it still had lots of oil in it---just not enough to make it worth drilling.

2)  Regulations can make things worse by introducing unintended consequences.  BP would probably not have been drilling in 5000 feet of water, but in shallower waters instead, if government policies hadn't forced them to do so.  A broken well would have been much easier to fix in shallower water.

3)  Don't rely on the government to do much of anything right in a crisis.  They might (hey, even a stopped clock is right twice a day), but it seems unlinkely at this point.  They had laws on the books about how to deal with a large spill like this, and they didn't even follow their own procedures.  Instead, government agencies endlessly argued with other government agencies about what to do.  Don't depend on them---have your own personal emergency plans and supplies in place for natural disasters, etc.

Any other suggestions for lessons learned?
