  • What are the benefits of nuclear energy?

    Q: What are the benefits of nuclear energy?

    A: Nuclear energy offers a number of economic and environmental benefits. For starters, nuclear energy is by far the most concentrated energy type. A significant amount of nuclear energy can be produced from a small mass of fuel. Not only does this provide substantial energy, but it reduces fuel and production costs. In addition to being efficient, nuclear power plants do not emit carbon dioxide or smoke during the production process.

  • Why is conservation so important?

    Q: Why is conservation so important?

    A: Conservation, or the preservation of the world's natural resources, mitigates or reverses the negative effects of human activity. Many of the Earth's resources are non-renewable; once depleted, they are gone for good. Without intervention, oil, minerals and coal will eventually run out, and animals and plants may become extinct. Environmental pollution, species extinction and global climate change are all in part results of human mismanagement of the Earth's resources.

  • How do fossil fuels damage the environment?

    Q: How do fossil fuels damage the environment?

    A: The primary reason that fossil fuels are harmful to the environment is that their use produces large amounts of greenhouse gases. These gases cause heat to build up in the atmosphere and raise the average temperature of the planet. Fossil fuels also pollute the air when they're burned and may cause environmental damage when they're mined.

  • How does nuclear waste affect the environment?

    Q: How does nuclear waste affect the environment?

    A: Nuclear waste affects the environment primarily because it's extremely difficult to dispose of properly. If it isn't disposed of properly, it can cause extensive groundwater and soil contamination. The elements that make up nuclear waste often have long half-lives, which means that it may take millions or billions of years before the waste is safe for humans to be around.
