This video segment points out that we are consuming fossil fuels at a rate far faster than they can be produced in the Earth, and that combustion of these materials to produce energy releases carbon dioxide, a greenhouse gas. It also discusses some current and future alternatives for supplying energy, and describes some of the benefits and limitations inherent in each. The segment is six minutes nine seconds in length. A background essay and discussion questions are included.
