2) Recycle - Think of all the turtles choking on your plastic bottle! Eugh
3) Use natural light from the sun during the day when indoors - try not to waste energy by turning on the lights
4) Don't take the free plastic bags at the supermarket to put your brocolli/bananas in... You know you'll throw them away once you get home. Also - reuse the plastic bags you already have. Don't keep buying them!
5) If you can walk to the shops, then don't take the car. You need more exercise anyways. LOL
6) Don't leave your computer on at the office when you know you're going to take a long lunch. Switch it off.
7) Don't throw away your old clothes in the bin - collect them in a box. And give it away to charity or the needy once the box is full.
