Think Globally, Date Locally
I hadn’t thought about it, but of course, those long-distance relationships are tough for more than the people separated my miles. All of that travel back and forth has a significant carbon footprint, especially since (as that article points out), the greenhouse gases that planes emit are thought to have a higher impact than ground transport. Even if your long-distance sweetie is within driving distance, that’s still a lot of gasoline that you’re using up. See the piece on Slate for the relevant links, if you like.
Now, I don’t think we need to berate folks in long-distance relationships. It’s a tough situation to begin with and they don’t need anyone making it worse. Instead, I agree with the author of that article. As much as you possibly can, date locally. You’ll be able to see each other more often, which is good for you. You’ll be able to use less oil, which is good for everyone. And if you do find a new love who happens to be further away, use public transport. You can spend your travel time writing sweet notes, fantasizing about your lover, or plotting a romantic evening. That way, everyone wins.
