This week, take the initiative to just say no. Pay attention when you go out to pick up your regular morning muffin, lunchtime salad or mid-afternoon snack. Does your favorite shop always give you a big stack of napkins and cutlery, even if you just toss it all in the trash back at work? It's OK to say no to excess packaging. In fact, most stores will appreciate it. The less they have to give away, the more money they save.
