Team Seas (stylized as #TEAMSEAS) was an international collaborative fundraiser that was started by YouTubers MrBeast and Mark Rober as a follow-up to Team Trees. The fundraiser succeeded in raising over 34 million U.S. dollars. All of the donations from the fundraiser went to the Ocean Conservancy and The Ocean Cleanup, with the organisations splitting the donations. The fundraiser pledged to remove 30,000,000 pounds (14,000,000 kg) of marine debris from the ocean by removing 1 pound (0.45 kg) of marine debris from the ocean for every 1 dollar donated.
