Nuclear Power: The Key to our Future here's the story if you want to read it to understand the question.

Question

People all over the world use nuclear energy. Most people would agree that it is a good source of electricity.



Many groups speak in favor of nuclear energy. Actors, athletes, and other famous people have been ambitious in promoting their use. Many of these people have been tireless in their efforts. They have received criticism from people who question its safety.



Some people believe nuclear energy could have negative effects on the environment. It is possible if we are not careful. However, nuclear energy saves natural resources. It gives us more power than other energy sources. Uranium is used to create nuclear energy. Then it becomes electricity. Another way to make electricity is by burning coal. One pound of uranium produces more energy than three million pounds of coal. This means fewer resources are used. Also, burning fuels causes air pollution. Uranium does not cause air pollution.

Nuclear energy is not without problems. What do we do with the used uranium? Uranium gives off radiation or dangerous energy waves. It gives off radiation for a long time. It takes thousands of years before this material is fully decayed. When all the uranium has wasted away, it is safe. Until then, nuclear material must be handled with care. However, it is possible that we will find a safe way to store used nuclear material.



We will not have huge amounts of natural resources such as coal and oil forever. We must find other ways to create energy. People need to share the same vision of how we will get our energy. Nuclear energy is the key to the future!
