Don't want to minimise this disaster, but as the WP article states (with refs), as well as my kid's school research on this

, the size of this thing is not as big as Texas. At least not the visible part that looks like a mountain of garbage.
The invisible (tiny bits) parts are 100% all over though.
Last time I accompanied the missus at a resort for a week, I got bored by day 1 and there was no decent windsurfing.
I resorted to getting garbage bags from the hotel and running up and down the coastline and filling the bags with plastic litter. Did that all week, at least it was exercise. Didn't make a dent of course.
Shame on litterers of all shapes and size and nationalities.
