Yurika Ayukawa, the special adviser on climate change to the environmental organization World Wide Fund for Nature Japan (WWF Japan), believes the key to combating global warming lies in changing humans' means of generating energy.
"Japan should emphasize not nuclear power but natural gas and renewable energies, and it should develop unused energy sources," she said.
Ayukawa, who became an expert on nuclear issues while working for the nonprofit organization Citizens' Nuclear Information Center, said that in light of her experience she realizes that nuclear power causes many problems.
