Sociobiologist, futurist and author Rebecca Costa joins Safety Talk on this episode. Rebecca spent four decades in Silicon Valley working at the cutting edge of technology, with clients such as Hewlett-Packard, Apple, Oracle, GE, and others.  She puts forward some urgent and sophisticated ideas about civilizational collapse.  In 2017 she published On The Verge, in which she discusses the value of acting preemptively to prevent damage when we know a problem is imminent, on scales global and personal, and new data showing that this is possible.
