If you want to maintain a sustainable supply of fish you have to farm the fish, rather than mine them. So putting your money into fishing fleets that are going to exacerbate the problem by over-fishing is not the way to preserve the underlying asset.

Rumors of my wealth are greatly exaggerated. I have never been interested in money.

I was with Ted Turner when he came to see Kofi Annan - the Secretary-General of the UN - to announce his decision to put $1 billion to the service of UN projects and programs.

What pleases me most is that sustainable development is on almost everybody's agenda now.

Don't accept that you can't make a difference. Because if you can't make a difference, you won't make a difference, and if you put a multiplier on that we will continue on an unsustainable pathway.

We need what I have often called an ecological approach to the management of these resources and we do not have that now. We have the inertia of past habits, unsustainable habits.

Inertia is a powerful force in human and political affairs.
