Top 10 TED Talks - 3 - Learning the Limits

Limits are frequently the theme of Sustainability conversations, and my third Top 10 TED Talk is precisely about the limits of environmental stability.  Johan Rockstrom, director of the Stockholm Environment Institute and the Stockholm Resilience Centre, discusses his work identifying exactly what the environmental limits are, and where we are in relation to those limits.  Rockstrom lead a group of researches in developing 9 "planetary life support systems" that are being stressed by human activity, and the limits of how much we can stress them before they collapse.  The good news is, we've only crossed three of those limits!  I think you can infer the bad news.

Rockstrom is both informative and persuasive, and uses some theatrical tropes and props to help get his points across.  It is a very effective description of what exactly is meant by existing within the limits of a healthy planet.
