I came across it recently and watched it with my wife and some friends tonight. It goes into great detail how the mega construction companies are illegally dredging the ocean floor for sea sand to feed the need of these companies need for concrete. Islands and beaches are disappearing around the world to feed the greedy money grubbing business'. As a result, beach erosion and higher oceans levels are eating away coastlines all around the world. Governments are bought off to turn a blind eye to the problem and the black market sand mafia continues to turn the worlds beach sand into concrete. They are literally removing mountains of pristine ocean sand on a daily basis by dreading the ocean floor and destroying the coral and the ecosystem all in the name of profit. A very informative, yet disturbing, documentary that more people need to see. People should be aware of the illegal sand mafia that are hard at work destroying Earth.
