Pygmies in the DRC, by Randy Olson.

We teamed up underwater photographer Brian Skerry and photojournalist Randy Olson to document the depletion of the world's fisheries.

Back on land, Randy Olson photographed a makeshift fish market in Africa, where the remains of filleted fish were sold to the locals, the main parts having already been sent to Europe.

In three dimensions, we did a project last year at TEDGlobal with Autodesk and Arthur Olson where we looked at autonomous parts so individual parts not pre connected that can come together on their own.

Indeed, agreements like last year s deal between China and the United States to reduce carbon dioxide emissions not to mention initiatives to mobilize business, such as We Mean Business are unlikely to happen without them. Nonetheless, as Mancur Olson famously observed, it is the individual interests of the parties that drive collective success.

The renowned American economist Mancur Olson argued that stagnation in developed economies results from cartels and lobbies becoming more numerous and powerful over time, until they eventually drain a country s economic dynamism. Preserving a competitive environment in which markets remain open and contestable is the best tonic, because firms must constantly innovate and perform better under such conditions.
