I will purchase produce and meat from a local farmers market or food co-op.

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

I will power down my computer and monitor when not using it for more than 2 hours, saving up to (1.1) lbs of CO2 per day that I do this.

I will complete an online energy audit of my home, office, or dorm room and identify my next steps for saving energy.

I will write down three things every day for two weeks that I am grateful for, or send one email every day thanking or praising someone.

I will join a smoking cessation program, and stick with it during the challenge, cutting out harmful air pollutants while improving my own health.

I will get my Core Four Biometrics tests (blood pressure, cholesterol, blood sugar and BMI).

I will involve my children in completing the actions I have selected during the challenge.

I will join my neighborhood association or another local group.
