The North Pacific Gyre is a section of the Pacific Ocean between Hawaii and California that is accumulating trash due to the nature of its water currents. This garbage patch in the ocean consists of trash debris and non-biodegradable plastic that just breaks up into more tiny pieces.
It says that there is 7 million tons of floating waste spanning an area twice the size of Texas. Birds and wildlife die when they mistaken these plastic bits as food. A lot of these garbage get washed up on beaches.
The latimes.com also has some video pieces on the North Pacific Gyre here.

The reason why there is not a lot of good photos of the North Pacific Gyre is that most of the garbage is just underwater and is somewhat spread out as explained in theoystersgarter.com.
