My suggestion is that we should first work to ensure the Third World has clean drinking water and sanitation.

We've had the U.N. for almost 60 years, yet we've never actually made a fundamental list of all the big things that we can do in the world, and said, 'Which of them should we do first?'

...children born today-in both the industrialized world and developing countries-will live longer and be healthier, they will get more food, a better education, a higher standard of living, more leisure time and far more possibilities-without the global environment being destroyed.

I'm a vegetarian, but I don't expect other people not to eat meat.

The Kyoto treaty has an estimated cost of between US$150 and $350 billion a year, starting in 2010.

Surely the biggest problem we have in the world is that we all die. But we don't have a technology to solve that, right? So the point is not to prioritize problems; the point is to prioritize solutions to problems.

Of course, the world is full of problems. But on the other hand it's important to get the sense... are we generally moving in the right direction or the wrong direction?
