In an earlier post I talked about the Great Pacific Garbage Patch. I came across a serires of videos that a group at VBS.TV put together that details their journey of sailing from California to the garbage patch and talking with researchers/scientists along the way about the patch. The videos give you a much better take on the garbage patch than just looking at an infographic.
There are 12 videos in the series starting with part 1 here. They get to the garbage patch in part 9. Each video is just a few minutes long. Oh, and there is language being used so be careful where you watch them.
oh, I have a power point for you!!!
