When I first started, it was really an innocent response to the needs of women in rural areas. When we started planting trees to meet their needs, there was nothing beyond that. I did not see all the issues that I have to come to deal with.

People are dynamic. They change, and soon as there are enough of you, things change [for a whole society].

Those of us who witness the degraded state of the environment and the suffering that comes with it cannot afford to be complacent. We continue to be restless. If we really carry the burden, we are driven to action. We cannot tire or give up. We owe it to the present and future generations of all species to rise up and walk!

The little grassroots people can change this world.

Sometimes I feel frustration at the bureaucracy for not moving fast enough to deliver in the way that I would prefer. But that is probably because I have worked for many years in the civil society, which tends to move much faster than government.

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.

I'm sure the government of Qatar is not coming in to grow food for the people of Kenya; it's coming to grow food to sell. If it can also sell to the people of Kenya, well, then good. I think that the moves can be helpful, but I think that the history that Africa knows, as I say in my book, has been a history of exploitation.
