U.S. Sen. Sheldon Whitehouse, R-R.I., and Dennis Nixon, who heads Rhode Island’s Sea Grant program, brought a message to people on World Oceans Day: The oceans are warming, increasingly acidified and littered with debris and sea levels are rising.

Whitehouse mentioned the Volvo Ocean Race Oceans Summit, which addressed marine debris, including the plastic that sailors have seen in even the most distant seas.

“They’ve taken care of us for a long time,” Whitehouse said in a video. “It’s time for us to take better care of our oceans.”
