Don't leave the water running. Turn off the water when brushing your teeth or washing the car.
Flick off the light when you leave a room. Power plants burn fuels to create energy for your light bulb. Burning fuel makes smog that pollutes the atmosphere and adds to global warming.
Print on both sides of the page at work. It's easy to change your printer settings - you'll use half the paper and save trees.

Ditch the paper cups. Bring in a glass to keep at school or work instead of using the paper ones by the water cooler.
Use the right settings on your appliances. Many appliances, like your dishwasher, washing machine and refrigerator, come with energy-saving settings. Make sure they are turned on.
