G.U. love is bad for the environment

Barron YoungSmith in Slate http://www.slate.com/id/2202431/ points out long distance relationships hurt the environment, speaking of one couple in particular who see each other once a month:

 

"Indeed, for her, breaking up would be about 10 times better for the environment than going vegetarian." 

 

"The Local Food movement encourages us to cut CO₂ emissions by calculating food miles—the distance a meal travels from production to the dinner table—and eating only what's produced within a 100-mile radius. Isn't it time for a Date Local movement, too?"

 

In the old days when I was a commuter student at UMSL, dates who lived across town were "G.U." -- geographically undesirable.  I haven't heard that term much since, but it may be coming back into fashion.
