Sorry to start the New Year on a down note, but the January 1, 2008 issue of the New York Times has a review I wrote about a book called No Way Home. It’s a sobering look at the decline of the world’s great migrations. I’ve written a fair amount about the marvels of migration in recent months (here, here, and here), so it’s sad to see that there might not be much to write about in years to come unless the world gets its act together.
