How will clean energy help future generations?

Appetite for Destruction

As America tries to wean itself off expensive foreign oil while creating jobs at home, alternative energy has become one of the most debated issues of the 21st century. Although critics charge that the myriad of promises about going green are a mirage, others argue the benefits are real, especially for future generations.

The problem is that for centuries we humans have been burning fossil fuels, such as oil and coal, to power our lives. When those fuels burn, deadly heat-trapping greenhouse gases, including carbon dioxide, spew into the air resulting in air pollution and massive changes in Earth’s climate and environment -- global warming. As global warming worsens, look for more severe droughts where water is scarce, and more catastrophic floods where it is not.
