I will keep track and reduce my consumption of refined sugars, including sweetened beverages, candy, and processed foods.

I will save up to 8 gallons (30 L) of water each day by turning it off while brushing my teeth.

I will sign up for a car-sharing service or organize car sharing with my neighbors or classmates to cut down on the number of vehicles on the road.

I will adopt a "Needs Vs. Wants" approach and only buy things I need.

I will spend 15 minutes each day maintaining a record of all my purchases and learning about my spending habits.
