Now that you've remembered that during an Air Quality Advisory day you should cut down on activities that can cause air pollution to form, you begin to plan your day.
Your list of chores for the day includes mowing the lawn. You: 1. Decide to conserve energy (your own, that is) by using the riding mower.
2. Put off mowing until tonight, when it's cooler and UV rays are weakest, and use the gas-powered push mower.
3. Use the person-powered push mower - what a good workout!
