The opacity is the difference between profit and loss. If every airline seat that could be sold- were sold at the lowest possible price, the industry would lose billions. If every airline seat that could be sold- were sold at the highest possible price… It would make billions.

There is a strong possibility that the relationship between humans and their environment would be so fundamentally changed that hundreds of millions of people, perhaps billions, would have to move. History tells us that this carries serious risks of severe and extended conflict.

I can't advertise chewing gum to my children because it's unethical, but I can feed them all sorts of narratives that will have a profound impact on their personal trajectories. It's quite an extraordinarily hypocritical position.

China for example, aims to increase their buying by 400,000 barrels a day in the last quarter of 2012, and will be adding over 750,000 barrels of new refining capacity. That economic engine is still turning.

I dreamt of Farfetch for the love of fashion. I was absolutely determined to create something in the intersection of both fashion and tech – my two passions.
