The Millennials, a generation born digital, will have a much stronger impact on social behaviour than we currently assume. Global climate change and resource security will influence our lives in substantial ways.

We are now living in a completely digitalized world and a completely globalized world, so we have to find some new mechanisms and values to deal with this post-digitalized and post-globalized world.

For many years prior to the 1990s, European integration was embraced and supported by a large majority of citizens. A united Europe, bound by commonly-held democratic values, was perceived as an essential and effective buffer against the Soviet empire. A united Europe made a repeat of the First and Second World Wars almost unthinkable.

An overwhelming number of economists, international civil servants, and policy-makers argue that a fragmentation of the Eurozone would cause a new depression and massive wealth destruction around the world. It would also end the period of economic integration that has characterized world politics since the end of the Cold War.

Sometimes, if a country's currency is overvalued in real terms, and it looks like the current account is going to be in deficit for the foreseeable future, devaluation can make sense.

Europe has grown to 27 member states, encompassing an amazing diversity and richness. Some argue this is part of the problem: Europe is simply too big and culturally disparate to be managed properly. But look to India for an example of how social unity can be forged within a culturally, linguistically, and ethnically complex nation.

Of course, some people call me one of the most well-networked people in the world, but I am a very unsocial person - I never go to a cocktail party; I am never seen at a charity event. I have one exception: I'm a member of the board for one of the big European music festivals, so I participate, with pleasure, in concerts.

I like, very much, nature. Since I'm always together with people, I like to retreat.

When the World Economic Forum was established in 1971, the global population was four billion, of which 50% lived in poverty.

Environmental pollution, terrorism, and many other global threats do not stop at borders. We all bear global responsibility and thus need a global identity to enable us to cope with them. We must learn to integrate different levels of identity in ourselves. What matters is not either/or, but both/and.
