    Ways to Host an Eco-Friendly Cookout

    Eating in the open air may feel eco-friendly, but outdoor dining can result in unnecessary waste if you aren't careful.____If you keep that in mind throughout your preparations, you'll be off to a good start.

Reduce, Reuse, Recycle

    Skip the paper invitations and use online services like Email, or Facebook events____This way you'll avoid ending up with five different potato salads that go uneaten.

They're also far less breakable than regular glasses____ If guests know which glass is theirs, they don't need to reach for another one, which cuts down on the cleanup you'll be doing.

____
