We are very fond of blaming the poor for destroying the environment. But often it is the powerful, including governments, that are responsible.

I have always felt that perhaps women have sometimes almost embraced the same values as men, and the same character as men, because they are in the men's world, and they are trying to fit into a system that men have created. And maybe in truth when there is a critical mass of women who play that role in governments, then we will see whether women can really manage power in a way that is less destructive than the way that men have used power.

For me planting a tree is a very doable thing. It's not complicated, it doesn't require technology, it doesn't require much knowledge, but it can be a very important entry point into communities understanding how they destroy their own resources, but how they can also restore those resources, and not wait for their government or international agencies to come and help them.

Every one of us can make a contribution. And quite often we are looking for the big things and forget that, wherever we are, we can make a contribution. Sometimes I tell myself, I may only be planting a tree here, but just imagine what's happening if there are billions of people out there doing something. Just imagine the power of what we can do.

There are certain areas where foreign investors can help the local people to generate wealth, and improve their quality of life. Some companies, for example, Del Monte, which produces pineapples in Kenya, pay a huge amount of taxes, I am sure, to the Kenyan government, and they do create jobs for thousands of locals.

As long as we have all these conflicts, it is the women who will continue to suffer, so that is one reason why I guess as women we should really work for peace, because we know how painful wars can be to us and our daughters.

The issue of climate change, it really does bring home the fact that we are on one planet, and that some of the impact of what human beings do in one corner of the world is going to affect people in a distant corner of the world. So we may still feel very far from each other, but we are really very close to each other because of the changes we have made with travel and technology and especially the information technology.
