This April, the SciFri Book Club will read Pulitzer Prize finalist Dan Egan’s The Devil’s Element: Phosphorus and a World Out of Balance. Published this March, The Devil’s Element traces the history of phosphorus, and uncovers how this powerful element has been used to both greatly benefit and severely endanger human beings—and the world. Phosphorus is particularly known as a potent fertilizer, but its overuse has resulted in toxic algae blooms and poisonous waterway “dead zones.” For the element that can be used to make both rich soil and rat poison, deciding the future of phosphorus will affect how we maintain functional food systems for all of humankind.

The Devil’s Element brings together a range of topics, including chemistry, agricultural engineering, ecosystem ecology, history, energy, and more—and we’ll touch on these ideas throughout this Book Club season. You can get your copy from your local bookstore or on Bookshop.org.

This Book Club season kicks off Saturday, April 1, and you can read along with us! We’ll be (loosely) following this schedule, but all our readers are welcome to join us at their own pace:

  • Chapters 1-3 from April 1-9

  • Chapters 7-9 from April 17-23
  • Final thoughts from April 24-30
