No matter where you go this summer, there are a few essentials that are important to have on hand to ensure a sustainable, healthy summer. Sunglasses are a give-in, but wearing an ethical pair (made from environmentally-friendly materials or are part of a one-for-one program) will make you feel good every time you put them on. And when you stop to get an iced coffee, its great to prevent waste by bringing your own tumbler - and reusable shopping bag if you want to pick up some other treats while you're out. Finally, you've heard it before, but don't leave the house without sunscreen! Pickup a chemical free tube and slather it on throughout the day.
