““Let’s say I do bother, big time. I turn my life upside-down, start biking to work, plant a big garden, turn down the thermostat so low I need the Jimmy Carter signature cardigan, forsake the clothes dryer for a laundry line across the yard, trade in the station wagon for a hybrid, get off the beef, go completely local. I could theoretically do all that, but what would be the point when I know full well that halfway around the world there lives my evil twin, some carbon-footprint doppelgänger who’s eager to swallow every bite of meat I forswear and positively itching to replace every last pound of carbon dioxide I’m struggling no longer to emit. So what exactly would I have to show for all my trouble?””
