Alex Steffen (born c. 1968) is an American futurist who writes and speaks about sustainability and the future of the planet. He emphasizes the importance of imagining persuasive, positive possible futures: “It’s literally true that we can’t build what we can’t imagine,... The fact that we haven’t compellingly imagined a thriving, dynamic, sustainable world is a major reason we don’t already live in one. ”From 2003–2010, Steffen was Executive Editor at the website Worldchanging. Worldchanging practiced "solutions-based journalism." The nonprofit announced the goal of its work was to highlight new solutions to what the editorial team saw as the planet's most pressing problems, rather than to spread news of those problems or critiques of their causes. The site won or was nominated for a number of awards and prizes, including: 2005 won the Utne Independent Press Award; 2006, finalist for a Webby for Best Blog; 2007 finalist for a Webby for Best Magazine, as well as for Bloggie awards for Best Group Weblog and Best Writing for a Weblog; won the Green Prize for Sustainable Literature for its book; won Organic Design Award; Prix Ars Electronica nominee; 2008 named a Webby Official Honoree. In 2017, following the election of President Donald Trump, Steffen modified his style to a form of 'anticipatory journalism'; taking the same themes as the Heroic Future and setting them in the near future, post-Trump. This series of newsletters are titled The Nearly Now.
