U.N. Secretary-General Kofi Annan asked world leaders yesterday to pick up the pace on protecting the environment. “We may be moving in the right direction, but we are moving too slowly. We are failing in our responsibility to future generations and even this one,” said Annan, speaking at a conference in Bangladesh. He said that the burden to act on problems like global warming should fall on the European Union, Japan, and the U.S. because they were responsible for causing the problems in the first place. He suggested that the industrialized nations step up to the plate in preparation for next year’s Earth Summit in Johannesburg, South Africa.
