The people are learning that you cannot leave decisions only to leaders. Local groups have to create the political will for change, rather than waiting for others to do things for them. That is where positive, and sustainable, change begins.

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

Until you dig a hole, you plant a tree, you water it and make it survive, you haven't done a thing. You are just talking.

It is wonderful when you don't have the fear, and a lot of the time I don't ... I focus on what needs to be done instead.

We can work together for a better world with men and women of goodwill, those who radiate the intrinsic goodness of humankind. To do so effectively, the world needs a global ethic with values which give meaning to life experiences and, more than religious institutions and dogmas, sustain the non-material dimension of humanity. Mankind's universal values of love, compassion, solidarity, caring and tolerance should form the basis for this global ethic which should permeate culture, politics, trade, religion and philosophy. It should also permeate the extended family of the United Nations.

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.

First of all, farmers should work with universities and research institutions in the country, and hopefully with the government.
