Energy and the Environment
 
As nonrenewable energy sources are depleted, the level of pollution in the environment is rising. Because fossil fuels make the bulk of our energy use today, most pollution is combustion generated. The harmful effects of these pollutants on the environment are becoming more pronounced, as evidenced by increased level of toxins in our atmosphere, rise in global warming, and depletion of ozone in the stratosphere. In addition to fossil fuels, the burn-up of nuclear fuel has resulted in pile up of tremendous amount of nuclear waste. Unlike other pollutants that can become ineffective in periods of many months or years, the nuclear waste material remains radioactive for a very long time and practically permanent relative to the span of human life.

As nonrenewable energy sources are depleted, the level of pollution in the environment is rising. Because fossil fuels make the bulk of our energy use today, most pollution is combustion generated. The harmful effects of these pollutants on the environment are becoming more pronounced, as evidenced by increased level of toxins in our atmosphere, rise in global warming, and depletion of ozone in the stratosphere. In addition to fossil fuels, the burn-up of nuclear fuel has resulted in pile up of tremendous amount of nuclear waste. Unlike other pollutants that can become ineffective in periods of many months or years, the nuclear waste material remains radioactive for a very long time and practically permanent relative to the span of human life.
