Note: This column was originally titled, "A Stupid Attack on Smart Growth," intended as a pun on 'smart' and 'stupid.' However, that sounds harsh so I retitled it. - T.L.

The National Association of Home Builders (NAHB) has a well-financed campaign to discourage communities from considering smart growth as a possible way to conserve energy and reduce pollution emissions. They contend that compact development has little effect on travel activity and so provides minimal benefits.

An article posted last week by the Guardian and highlighted yesterday by Treehugger.com cites recent studies as well as data from maritime industry sources that the combination of quantity and quality of low-grade bunker fuel used in the massive engines of freight vessels may result in more emissions than all the cars in the world!  I don’t mean to wax sensationalist here, this is what is stated in the article.  If the truth is anywhere near the statement, then the idea of
