What others are doing
Kate summarises why climate change is bad for biodiversity, otherwise known as the web of life (though as a couple of comments point out, we're really talking about anthropogenic environmental change, not just climate change, as there are other factors contributing to the current precipitous biodiversity decline).
Jeremy is in search of the biodegradable shoe. He also thinks there are three basic paths ahead for the world over this century.
Bill discusses what he thinks might be the most popular tax in history.
David distinguishes (very helpfully) between stuff and things, and while he's dishing out useful advice, he also gives some tips on how to make trillions of dollars.
Halden is a little underwhelmed by ecumenism.
And Brad relates a tale of two Protestantisms, in which O'Donovan sides with the Augustinian English Anglicans against the Donatist Scots Presbyterians (perhaps unsurprisingly, since O'Donovan is an English Anglican who happens to live in Scotland). If nothing after that last comma made sense, don't worry, the post itself is very readable.
