According to Professor Marvin Burnham of the New England Institute of Technology, we have to start saving coal, oil and gas before it is too late; and solar power is the only alternative. However, many people do not approve of using nuclear power because it’s very dangerous. What would happen if there was a serious nuclear accident? Radioactivity causes cancer and may badly affect the future generations. The most effective thing is that we should use natural resources as economical as possible.
