Lights should be turned off in unoccupied conference rooms and offices. If you walk by an empty conference room, switch the light off. Turn lights off in your own office when you'll be gone for more that ten minutes.
Smart landscaping
Avoid planting too much lawn. Lawns need lots of water and provide no habitat for local wildlife. Create a meadow of indigenous wildflowers, plant an attractive ground cover, or plant an organic herb and vegetable garden instead. Consult your local extension office (normally affiliated with a college or university) for guidance.
Fueling a boat
If you own a boat, protect the water by always using a funnel when refueling from a gas can. Be equally conscientious when refueling from a gas pump to avoid spills.
