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.

If you care enough about something, as opposed to writing a cheque and letting someone else do it, or bitching about the problem, I say… 'you know what? If I care enough about something? I'm going to go out and do it…' that means I'm giving one of the most valuable things I have… my time. In life, you can always make more money and get more of everything- but one thing you can never get back is the time you give.

One can certainly live their life happily, here on earth never looking up or contemplating what's out there… but for many people (myself included) when you become aware of how much is out there? You feel this compelling pull of curiosity to understand.

Saying people have the ability to participate in decisions, and actually ensuring they can, should not be mutually exclusive. Our nations, economies and companies can perform far better where we genuinely allow and encourage participation in governance and policy from all stakeholders.

Too often when we find someone disagreeing with us, our question is about why. Why do you believe this ridiculous thing? What tends to work better is a how question... This kind of approach helps to view the real complexity of a situation and reveals gaps in knowledge.

My wife Freada coined a phrase, distance travelled. We're very interested in where somebody started in life, and what hurdles and barriers they have already overcome in their journey – and how that grit has got them to where they are now.

When global markets open up, if you're selling t-shirts in the US or Denmark, you're disadvantaged because countries like Bangladesh produce them more efficiently and cheaply. This has fuelled arguments advocating caution when it comes to free trade. We've conducted what is, to my knowledge, the first study attempting to quantify both the benefits and costs of trade, rather than focusing solely on the benefits.

We assumed matter was fundamental when we probably should have prioritised consciousness. If we viewed consciousness as the prima materia of reality itself, I think we'd know a lot more about these intelligences and hidden agents than we do today, had we not gone down that strict materialist path all those years ago.

I know that there is an arc and that one day, either at my choosing or the club's, I will begin the downward part of the arc. I know when this is coming because people at the club stop talking about the future. That is a big sign.

I think life matters because it gives meaning to the universe. Without life, the universe is devoid of meaning. We aren't the universe, but we are a vital part of it, we are what gives this universe meaning.

Our role as coaches is essentially to help players utilise 100% of their potential. That, to me, is the essence of our job.

We're heading to a world where all our energy is derived from the sun and from renewables, a world where we will have a squanderable abundance of energy. There's 6,000 times more energy hitting the surface of the Earth than we consume as a species.
