I will test drive an electric bike at a local distributor to see if it makes sense to use one in place of my car, or to extend the area I can cover by bike.

I will take a walk for 45 minutes each day and take note of the infrastructure that makes walking more or less enjoyable, accessible, and possible.

I will practice the "5 Rs" — refuse, reduce, reuse, repurpose, and recycle — to reduce my waste more than I can with just recycling alone.

I will calculate the carbon emissions associated with my household and consider how different lifestyle choices could reduce our carbon footprint and our impact on the environment.

I will use smaller plates and/or serve smaller portions when dishing out food.

I will replace 3 incandescent lightbulbs with Energy Star-certified LED bulbs, saving up to $14 per fixture per year.

I will enjoy 1 meatless or vegan meals each day of the challenge.

Using the Seafood Watch guide, I will feature a sustainable seafood ingredient in a new recipe.

I will eat a heart healthy diet by adding 1 cups of fruits and vegetables each day to achieve at least 4 cups per day.
