Appalled by the treatment of environment protesters at Nairobi's Karura Forest, the United Nations Executive Director, Klau Toepfer, said that violence and intimidation was not the way to deal with sensitive enviornmental issues like Karura which, he said, must be handled by a process of dialogue and cooperation. Repeating his view that the Karura forest is a precious natural resource which the city of Nairobi cannot afford to lose, Toepfer said that the destruction must stop as the loss of this valuable ecosytem will have serious environmental implications.
