Oysters

Oysters become a controversial topic at this time of year.  Some people think they're delicious and a vital part of the Thanksgiving menu.  Others think they taste like rubbery snot and don't want them within fifty feet of their Thanksgiving dinner.  Whichever camp you fall in, you may be alarmed to see this page from the National Oceanic and Atmospheric Administration which talks about the dramatic decline in ecologically important oyster reefs over the last few centuries:

Sadly, it may provide additional ammunition for both sides of the debate.  If things become too heated, perhaps you can distract everyone with a new debate about whether that starchy side dish should be called dressing or stuffing.  In any case, have a safe and happy holiday.
