Waves were breaking at UN Plaza in San Francisco today, but they weren’t waves of water.

On Friday, the Dopper Foundation, an international nonprofit based in Holland, invited Bay Area residents to San Francisco's UN Plaza to surf a huge 14 foot plastic wave. Made of 6,000 single-use plastic water bottles, Dopper hopes the wave will help raise awareness about how everyone can contribute to cleaner oceans.

“We are using every 4 seconds 6,000 plastic bottles in the US that we throw away, so 1 wave every 4 seconds,” said Merijn Everaarts, founder of Dopper. “Only 20 percent is being recycled, the rest will end up in landfills, in the streets, or in a river, and then it will end up in the ocean where it comes together in a huge plastic island where it kills all the sea life.”
