Ocean Revival 2020 is a team of serving and former serving Royal Marine Commandos, who have fought alongside each other in 45 Commando.
They have now teamed up to take the fight against plastic by attempting to raise awareness and help keep momentum in the fight against plastic in our oceans by rowing across the North Atlantic Ocean.
One of their team visited us in school and we've been following their adventure.
