Join the wave against single-use water bottles.

The Dopper Wave

Simple everyday actions. That’s all it takes to prevent large amounts of single-use plastic from entering our oceans. Sound good? Sign the pledge and promise to:

1. Ban single-use plastic water bottles
2. Drink from the tap whenever you can
3. Always bring your own reusable bottle
4. Encourage others to join the Dopper Wave too

You won’t be just a drop in the ocean: you will be a drop in a massive wave. A wave powerful enough to turn the tide. Forceful enough to wash away the plastic trash. A wave with enough impact to actually save our oceans.
