We can work together for a better world with men and women of goodwill, those who radiate the intrinsic goodness of humankind.

The essential role of the environment is still marginal in discussions about poverty. While we continue to debate these initiatives, environmental degradation, including the loss of biodiversity and topsoil, accelerates, causing development efforts to falter.

When resources are degraded, we start competing for them, whether it is at the local level in Kenya, where we had tribal clashes over land and water, or at the global level, where we are fighting over water, oil, and minerals. So one way to promote peace is to promote sustainable management and equitable distribution of resources.

Anybody can dig a hole and plant a tree. But make sure it survives. You have to nurture it, you have to water it, you have to keep at it until it becomes rooted so it can take care or itself. There are so many enemies of trees.

It was easy to persecute me without people feeling ashamed. It was easy to vilify me and project me as a woman who was not following the tradition of a 'good African woman' and as a highly educated elitist who was trying to show innocent African women ways of doing things that were not acceptable to African men.

We owe it to ourselves and to the next generation to conserve the environment so that we can bequeath our children a sustainable world that benefits all.

We cannot tire or give up. We owe it to the present and future generations of all species to rise up and walk!
