I just watched
MISSION BLUE
It's not so new already, from 2014 but it is really amazing.
It's about Sylvia Earle, she is a deep sea diver and marine biologist, and she it talking about the problems of trash in the ocean. How when she started her career the deep waters were always clear of anything from man but now every time she dives, however deep or where she always sees some kind of trash.
