Very good wake up call for Hawai'i as well as west coast of North America.  The Pacific 'Plastic Dump' has been in the news since the 90s, and some 27 years later, the amount of human-generated garbage has only increased.  

The efforts of the various groups are commendable and help confirm "Hawai'i, we have a problem".  But the long term solution is to address the source, which includes human mal-practices.

The critical issue of protecting sensitive endemic populations should concern everyone.  The plastic 'land mass' degrades extremely slowly- it also gets taken up by the food chain, eventually appearing on your dinner table.
