Stephen Porder is Professor of Ecology and Evolutionary Biology, a Fellow in the Institute at Brown for Environment and Society, and the Assistant Provost for Sustainability at Brown. Elemental is his new book looking at how life shapes Earth using basic elements we may take for granted. Read on to learn more about the book, and its wider relevance to other books now being published that discuss phosphorous.

Thanks, as always, to Elizabeth Kolbert for her book reviews, and in this case a nod to the Rich Earth Institute:
