Its nice to read an article that discusses the middle ground. Like it or not, most people are unlikely to adopt a vegetarian or vegan diet, at least not cold turkey, no pun intended. Rational discussions of ways to decrease our carbon footprint often lead to more and more small changes which add up. In the same way it might not be helpful for an overweight person to be encouraged to run a marathon, but instead to visit the gym three times a week for half an hour, might one day mean they do run that marathon. In the meantime, they're at the gym and even that is better than nothing. I work in a "green" industry. In my experience, a little education and a nudge in the right direction are way more effective than a lecture on how someone needs to do it all and do it right now.
