Journalism
Over the past 20 years, my 6,000-plus articles have appeared in magazines, newspapers, books and newsletters around the globe. I specialize in a few key areas: the environment, wildlife, cutting-edge technology, entrepreneurship, creativity and acts of kindness. My column about endangered species, Extinction Countdown, started way back in 2004, making it the world's first (and still the longest-running) news source devoted entirely to endangered species. It now appears at The Revelator, the news site that I edit.
