This video is simply discussing the problem with trash. Trash is filling the ocean and hurting the marine organisms.  This talks about the great pacific garbage patch, which is where all our trash ends up in the ocean.

If i had to rate this video from a 1-10, ten being the best, i would rate it a 7. 7 due to the fact that it's nothing I have never seen before. I did feel like the presentation was done well and i understand the point they were trying to get across. The only thing lowering the score is the fact that they didn't introduce anything new.
