Now when Nile perch was introduced [into Lake Victoria], I don't think enough research was done; maybe it was done, maybe it was not. But Nile perch is a huge fish. So it ate all the little fish, and it grew into a monster which the local people could not fish with their little boats and their little nets.

In Kenya women are the first victims of environmental degradation, because they are the ones who walk for hours looking for water, who fetch firewood, who provide food for their families.

One of the reasons why I say we all need to work together to save the Congo forest, because if we don't save the Congo forest, the Amazon forest and the southeast Asia forest, if those forests release the carbon they are trapping at the moment, much of what you will be doing in the North will be negated by the amount of carbon released into the atmosphere.

After Hurricane Katrina, many people said that the levees were not as effective as the natural vegetation that had been removed at the coast.
