  • 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.

  • 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.
