The rules are simple:

1. Throw it out, not down!

Trash belongs in the can, not on the ground. Don’t
litter.

2. Pick up just one piece!

One piece may seem small, but together it adds up.

3. Take a break and get some fresh air!

Grab a bag and take a quick walk.

4. Share your pictures!

Show off your Tuesday Trash Bag! Tag us in your post
and inspire someone else to join in.
