Church Teaching:

Laudato Si: On Care for Our Common Home by Pope Francis

Worth Reading:

A Walk in the Woods: Rediscovering America on the Appalachian Trail by Bill Bryson (Note: I have not seen the 2015 movie; only recommending the book here. The book does contain some mature material and would be best shared with teens after a parental previewing.)

Better Off: Flipping the Switch on Technology by Eric Brende
