The Brothers embark on a sailing adventure to the middle of the Pacific Ocean to the remote “Great Pacific Garbage Patch”, a massive collection of plastic waste congregated together by swirling ocean currents known as gyres. What does the patch look like? How does it affect wildlife and the seafood we eat? Where in the world did this inconceivably massive amount of plastic come from and from what human activities, and more importantly, what can be done about it? The Water Brothers bring us some answers to this strange and disturbing phenomenon.
