Lead the way when it comes to showing your friends how easy it is to help the environment just by changing your every day habits. Use the stairs instead of talking the elevator. Bike to outings rather than drive. Order vegetarian dishes off the menu when socializing over food. Shop at second-hand stores for used clothes instead of buying new items. Drink and serve fair-trade coffee. When your pals see that you walk the talk, they might be more inclined to follow in your footsteps.
