I was wondering, if this blog were to have a bumper sticker what would it say?  Not that this blog needs a sticker for its nonexistent bumper.  But I need at least one more post today, so how about:

Stop the Sixth Great Extinction!

What?  There are five mass extinctions, already?  Are we supposed to stop the sixth from coming?  Or is it happening now and we have to stop it?  How?
Yes it is a very bad sticker – unclear, polysyllabic, urgent, yet dull.  A slight improvement:

End the Sixth Great Extinction!

But now a light begins to dawn.  Since extinction events and geological epoch boundary layers are associated the sticker can be re-written as:

End the Anthropocene!

Much better, even though it may only end up as graffiti on my barn.
