The government of Qatar, as I mentioned, has proposed to come and lease Kenya's Tana River delta in order to farm there. What I am not sure of is, has an environmental impact assessment been made to ensure that exploiting this delta for agricultural activities is the best way we can use the delta?We must be concerned about the long-term impact of agricultural activities in the delta.

Education, if it means anything, should not take people away from the land, but instill in them even more respect for it, because educated people are in a position to understand what is being lost. The future of the planet concerns all of us, and all of us should do what we can to protect it. As I told the foresters, and the women, you don't need a diploma to plant a tree.

There is no reason why a company like Monsanto, for example, that is pushing GMOs, cannot go to Kenya, partner with the university, partner with the research institutions, and try to promote - in a responsible way - advanced techniques to help farmers. But this should be done in such a way that the farmers' livelihoods are not undermined because the government is irresponsible or careless, or because it is compromised.

Some say that AIDS came from the monkeys, and I doubt that because we have been living with monkeys from time immemorial, others say it was a curse from God, but I say it cannot be that.

You can't reduce poverty in a vacuum. You are doing it in an environment.

If Africa is left behind, she is going to continue pumping greenhouse gases into the atmosphere, especially carbon. She's going to continue logging the forests, she's going to continue burning charcoal, she is going to continue practicing agricultural activities that destroy the environment, and sooner or later Africa's problem will become a global problem.

What is really important is to educate people how to protect themselves and how to ensure that, despite their poverty, they can get tested and access drugs. So I just hope that those who can will make those drugs available.
