Extra Credit for A Day: 'The End of the Line' documentary

We have an extra 'A' day in the schedule due to PSAT/Career Day/Early Dismissal next Wednesday, so...

Today we will watch the documentary 'The End of the Line' 
As the world's demand for fish and other seafood increases and the technology available to commercial fisherman becomes more sophisticated, the annual harvest from global seaports has grown tremendously in recent years. However, the rise of industrialized fishing has not come without consequences, and many environmentalists and oceanographers believe that the current demand for fish and the methods used to fulfill it are taking an irreparable toll on the world's oceans, with some speculating that the seas could be literally fished-out by 2048 if current trends do not change. 
The ocean covers more than 70 percent of the surface of our planet. It's hard to imagine, but about 97 percent of the Earth's water can be found in our oceans. Of the tiny percentage that's not in the ocean, about two percent is frozen up in glaciers and ice caps.
