Toronto-based manufacturer Richters produces a "PotMaker" that uses two chunks of maple-wood to turn strips of newspaper into biodegradable seedling pots. Fill them with soil, plant your seedlings, and transfer them to the garden when you're ready to plant. The newspaper disintegrates shortly after planting.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
