Stewart Brand - 2005 May: Why environmentalists need new thinking about population growth, urbanization, genetically engineered organisms, and nuclear power. The environmentalist movement is dominated by dogmatic zealots who have a narrow concept of what needs to be done next. For these fanatics new information that demands a new approach is unwelcome. However, lots of new information is available. For instance, the world's human population has levelled off and is beginning to decline because most people live in cities where raising children is difficult. Environmentalists need to re-think their concerns. The big issue is climate change. We need to de-carbonize our energy production. The environmentalist's quasi-religious opposition to nuclear power is preventing this change. We are at a dangerous point where one more nuclear accident, even a small one, could seal off this avenue of hope. We need a revitalized nuclear initiative now.
