Each time you eat at a restaurant, take your own Tupperware® with you so that you can pack leftovers to go. This will save you from using so many Styrofoam® to-go boxes.
palmer SAYS:
When at a restaurant or cafeteria, take only the amount of napkins you think you will really need. You can always grab more! When you see your friends or coworkers leaving behind stacks of napkins, grab them and take them with you; stuff them in the glove-box of your car, or put them in your desk drawer. Once you pay attention, you will notice the massive amounts of wasted napkins, all waiting for you to rescue them!
