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.

We need to promote development that does not destroy our environment.

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

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.

We can love ourselves by loving the earth.

Resources on the planet are limited, and limited resources can come to an end. But there are also a lot of resources that are renewable. A lot of land, for example, can be reclaimed from the encroaching deserts.

I would like to call on young people to commit themselves to activities that contribute toward achieving their long-term dreams. They have the energy and creativity to shape a sustainable future. To the young people I say, you are a gift to your communities and indeed the world. You are our hope and our future.
