Mariana Trench: Deepest-ever sub dive finds plastic bag

An American explorer has found plastic waste on the seafloor while breaking the record for the deepest ever dive.

Victor Vescovo descended nearly 11km (seven miles) to the deepest place in the ocean – the Pacific Ocean’s Mariana Trench.

He spent four hours exploring the bottom of the trench in his submersible, built to withstand the immense pressure of the deep.

He found sea creatures, but also found a plastic bag and sweet wrappers.

It is the third time humans have reached the ocean’s extreme depths.
