Excerpts;

The number of cold-stunning and stranding events among juvenile Kemp’s ridley sea turtles, one of the world’s most endangered species, is increasing at an “alarming” rate and has moved north from Long Island Sound to Cape Cod Bay, say researchers at the University of Massachusetts Amherst, Mass Audubon and the University of Rhode Island.

Their recent study looked into what variables are most important in predicting the number of cold-stunning and stranding events among juvenile Kemp’s ridley sea turtles in Cape Cod Bay…

“Sand is the second most consumed natural resource, after water. The construction-building industry is by far the largest consumer of this finite resource. The traditional building of one average-sized house requires 200 tons of sand; a hospital requires 3,000 tons of sand; each kilometer of highway built requires 30,000 tons of sand… A nuclear plant, a staggering 12 million tons of sand…” Captions by: “Sand Wars” Multi Award-Winning Filmmaker Denis Delestrac (©-2013).

Excerpts;

Four kilometers off the Dubai coastline lies Europe. Or a version of it, at least.

Comprising six man-made islands styled after a mix of European countries and cities, when completed this $5 billion megaproject will be able to accommodate 16,000 tourists in the height of travel luxury…

Dubai’s Staggering Growth, NASA
To expand the possibilities for beachfront development, Dubai undertook a massive and controversial engineering project to create hundreds of artificial islands along its Persian Gulf coastline. Built from sand dredged from the sea floor, the islands are shaped in recognizable forms such as palm trees. The construction of the various islands off the coast of Dubai has resulted in changes in area wildlife, coastal erosion and alongshore sediment transport, and wave patterns.

Sand, Rarer Than One Thinks: A UNEP report (GEA-March 2014)
Despite the colossal quantities of sand and gravel being used, our increasing dependence on them and the significant impact that their extraction has on the environment, this issue has been mostly ignored by policy makers and remains largely unknown by the general public.
In March 2014 The United Nations released its first Report about sand mining. “Sand Wars” film documentary by Denis Delestrac – first broadcasted on the european Arte Channel, May 28th, 2013, where it became the highest rated documentary for 2013 – expressly inspired the United Nations Environment Programme (UNEP) to publish this 2014-Global Environmental Alert.
