By the middle of century, the temperature and humidity in parts of the world will be so high at parts of the year that the human system will not be able to cool itself, you are effectively being cooked. One of the places this will happen first, with potentially grave consequences, is the Arabian Peninsula- disrupting Hajj.

As you think this through, a lot of structure dissolves. And then the question becomes: what remains once all of that is gone? You could still choose to do these activities, of course, but there would no longer be any point—no instrumental need. You would only do them simply because you wanted to…

To me it was an adventure. I'm a hardened explorer and adventurer, and I remember the whole mission as an adventure with some awesome experiences and beautiful sights.

Around the world you've got somewhere between 1 and 2 billion people who are living in abject poverty. Economic growth offers the opportunity to reduce that 1 or 2 billion to 100,000–200,000 in the next phase.

We can't only rely on consumers making individual choices.

After the Holocaust, political antisemitism became widely discredited. However, what persisted were the cultural stereotypes – the entrenched narratives and stereotypes about Jews within the culture, ready to be drawn upon whenever they seemed relevant or useful.

Art is a vocation for me, not a career, not a job… you wouldn't say to a nun. 'so, how did you get into God?'
