There is no question that global warming will have a significant impact on already existing problems such as malaria, malnutrition, and water shortages. But this doesn't mean the best way to solve them is to cut carbon emissions.

The second thing is, if you want to do something about global warming, you have to think much more long-term. There is something wrong with saying we should start using renewables now, while they are still incredibly expensive.

The fact that we're catching more fish per person than we've ever done before doesn't mean that there are not particular places where we've managed fisheries badly.

...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.

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?

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

I'm an old member of Greenpeace. I worried intensely, as I think most of my friends did, that the world was coming apart.
