Here are some rules for my class on how everyone can help reduce waste:

1. Bring a refillable water bottle to class instead of disposable ones. This will reduce a lot of plastic waste.

2. Use reusable bags instead of single-use plastic bags when bringing things to class. A few reusable bags in your backpack or locker can make a big difference.

3. Turn off classroom lights and electronics when not in use or when leaving the room for a long period of time. This can save a lot of energy.

4. Use a pencil until it is too short to write with, instead of throwing it away when there is still enough lead left. This will reduce the amount of pencil waste.
