Environmentalists want industrialized nations to reduce the emission of greenhouse gases that warm the atmosphere. For more than twenty years, however, their pleas have been mostly ignored. Naval architects and ship designers can play a critical role in reducing greenhouse gases by designing effi cient ships that are safe and environment friendly. New innovations would enhance fuel effi ciency and encourage other industries to adopt new ways of thinking. Ship designers are already working to develop a ship that is safe, effi cient and ecologically friendly. Discover why these efforts are so important, and also learn the following: Ways a realistic and practical carbon dioxide index for ships can be established How much pollution commercial ships cause How safety concerns and other variables affect ship design What new designs could mean for the environment There is a great deal of uncertainty about why climates are changing, but this does not mean theories revolving around global warming are wrong. Discover new approaches to solve the problem, and take steps to understand the stakes involved with Global Climate Change and the Shipping Industry."
