This Land is Island

There are many kinds of islands. There’s your iconic sandy speck of land topped with a palm tree, but there’s also our home planet – an island in the vast seas of space. You might think of yourself as a biological island … until you tally the number of microbes living outside – and inside – your body.

We go island hopping, and consider the Scottish definition of an island – one man, one sheep – as well as the swelling threat of high water to island nations. Also, how species populate islands … and tricks for communicating with extraterrestrial islanders hanging out elsewhere in the cosmos.
