Nuclear power is one of the least damaging sources of energy for the environment, and the green movement must accept its expansion if the world is to avoid dangerous climate change, some of the world's leading conservation biologists have warned.

Rising demand for energy will place ever greater burdens on the natural world, threatening its rich biodiversity, unless societies accept nuclear power as a key part of the "energy mix", they said. And so the environmental movement and pressure groups such as Friends of the Earth and Greenpeace should drop their opposition to the building of nuclear power stations.
