Adult video website Pornhub has filmed a movie on a litter-filled beach to raise money to remove plastic from the world's oceans.

Every time the Dirtiest Porn Ever is played Pornhub will make a donation to Ocean Polymers – a non-profit organisation that is planning to launch a ship to collect and reprocess plastic from the sea.

"We're dirty here at Pornhub, but that doesn't mean our beaches need to be," explained Corey Price, vice president of Pornhub.

The movie features a couple known as Leolulu having sex on a beach surrounded by rubbish to demonstrate "how plastic and waste can ruin an otherwise beautiful scene".

As the couple has sex, litter pickers wearing Pornhub-branded boiler suits clean up around them.

The adult website launched the campaign as part of its Pornhub Cares initiative as there is increasing attention being paid to the state of the world's oceans.

"Ocean pollution has grown to become one of the most significant global issues of our lifetime, and it's only getting worse," continued Price.

"That's why it's imperative that we use our platform to raise awareness and inspire change – not just for the time being but for generations to come."

Alongside the video, Pornhub has created a website that advises its viewers how they can help avoid single-use plastics ending up in the ocean.

The site outlines three steps to help: buying as little plastic as possible, recycling all single-use plastics and cleaning up after yourself if you are enjoying the great outdoors.

Ocean Polymers believes that working with Pornhub will help spread the message about plastics pollution to people who may not otherwise be aware.

"We are all part of the problem and must work together to find solutions," said Heather Wigglesworth, executive director of Ocean Polymers.

"This is a brand with significant global reach spanning all demographics, so it is a very effective platform to raise awareness and support for the crisis we face in our oceans today. It would be great to see more companies of this size and stature taking the same responsibility with the audience they engage."

Ocean Polymers plans to clean the world's ocean by launching a converted tanker that will collect plastic from the water and process it into fuel. This fuel would then be used to power the tanker.

This is one of many proposed solutions to remove plastic from the sea. Dutch non-profit The Ocean Cleanup launched a floating device to collect plastic, however, earlier this year it broke down leading to many sustainability experts criticising its validity.

Speaking to Dezeen Cyrill Gutsch, founder of Parley for the Oceans, said that eliminating plastic from the seas is not possible.
