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.

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.

Top 10 TED Talks - 2 - Eating an Entire Earth
Next on my "no particular order" list of Top 10 TED Talks, Jonathan Foley describes how much land we use for food productions and shows us that we are practically eating an entire earth already. Foley does an excellent job of describing how agriculture impacts the Earth while keeping in perspective that it is a necessary part of human existence.
I like how Foley focuses in at the end on the solutions that are needed without loosing site of the scale and scope of the problems. As he says in the talk, Agriculture has been the most powerful force for change in the world since the last ice age, and rivals climate change in importance.
Bon Appetit!
