First, we are getting together and watching the game together using one TV (as opposed to staying at home and turning on separate TVs). Second, we are committed to using dish washer friendly utensils and dinnerware (nothing disposable). Third, we are bringing organic snacks (and hoping that the host serves organic food). Fourth, the host sent out electronic invitations via emails. Fifth, we are carpooling there and back. Finally, I'm also going to bring my kids' old clothes to share with our friends (it's great to recycle/reuse kids' clothes among friends).
If you are planning a Super Bowl party, hope you try some of the above eco-friendly tips.
