A Norfolk YouTuber with a regular audience of almost 400,000 people is getting behind a multi-million dollar campaign to clean up the ocean.

Matthew Park, aka Cookie Cutter, is encouraging viewers to make a donation to TeamSeas, a fundraiser launched by fellow creators including MrBeast.

The 20-year-old, from Dereham, is now one of thousands of creators to join the cause, which has a goal of raising $30m by January 1.

For every dollar donated, project partner Ocean Conservancy - a US-based environmental group - has pledged to remove a pound of rubbish during beach and ocean clean-ups around the world.

"I realised this was a really good thing to get involved with, and YouTube is really promoting it too," said Mr Park.

"It's definitely good to use your videos for something good. I have done a few things for charity before and I was keen to do whatever I could to help out this time."
