Sand is the second most consumed natural resource, after water. The construction-building industry is by far the largest consumer of this finite resource…”— Denis Delestrac, “Sand Wars” Multi Award-Winning Filmmaker (©-2013).

Excerpts;

The amount of material consumed by humanity has passed 100 billion tons every year, a report has revealed, but the proportion being recycled is falling.

The materials used by the global economy have quadrupled since 1970, far faster than the population, which has doubled. In the last two years, consumption has jumped by more than 8 percent, but the reuse of resources has fallen from 9.1 percent to 8.6 percent…

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, Rarer Than One Thinks.”
“Sand Wars” film documentary by Denis Delestrac – first broadcasted on the european Arte Channel, May 28th, 2013 in its french version: “Le Sable: enquête sur une disparition”, where it became the highest rated documentary for 2013 – expressly inspired the United Nations Environment Programme (UNEP) to publish this 2014-Global Environmental Alert.

Demand for sand: the largest mining industry no one talks about; Inhabitat (05-23-2019)
The world’s largest and perhaps most destructive mining industry is rarely discussed. Approximately 85 percent of all material mined from the earth is a simple and widely available resource: sand. Because it is so cheap and readily available, it is mined by everyone from guy with a shovel, to multi-million dollar machine operations.

Sand Wars, An Investigation Documentary, By Award-Winning Filmmaker Denis Delestrac (©-2013)
Is sand an infinite resource? Can the existing supply satisfy a gigantic demand fueled by construction booms? What are the consequences of intensive beach sand mining for the environment and the neighboring populations…? This investigative documentary takes us around the globe to unveil a new gold rush and a disturbing fact: the “Sand Wars” have begun…

Chinese paddlefish extinct after surviving 150 million years

dam-construction-china
Chinese companies and Chinese banks are now the biggest builders and financiers of global dam building. Chinese banks and companies are involved in some 307 dams in 74 different countries, particularly in Africa and Southeast Asia, including Kamchay Dam (Cambodia), Bakun Dam (Sarawak, Malaysia), Myitsone Dam (Burma) and Merowe Dam (Sudan).

Excerpts;

The Chinese paddlefish — one of the world’s largest freshwater fish — has officially been declared extinct after surviving some 150 million years.

The giant species, which measured as long as 23 feet and weighed as much as 1,100 pounds, has been killed off by overfishing and dam construction…

The biggest environmental story that no one knows about”: The recovery of groundfish off the West Coast


West Coast ground fish. Groundfish refers to more than 90 different types of roundfish, flatfish, rockfish, sharks, and skates off the West Coast. With a few exceptions, groundfish live on or near the bottom of the ocean. Fishermen from Washington, Oregon, and California catch them year-round using a variety of gear types. Photo and captions: NOAA

Excerpts;

A rare environmental success story is unfolding in waters off the U.S. West Coast.

After years of fear and uncertainty, bottom trawler fishermen — those who use nets to catch rockfish, bocaccio, sole, Pacific Ocean perch and other deep-dwelling fish — are making a comeback here, reinventing themselves as a sustainable industry less than two decades after authorities closed huge stretches of the Pacific Ocean because of the species’ depletion…

Biodiversity has substantially changed in one of the largest Mediterranean wetlands

Excerpts;

The Camargue in southern France is widely recognised as one of the largest and most biodiverse wetlands in the Mediterranean region.

Recent research has now shown that grasshoppers, crickets and locusts, comprising orthopterans, and also dragonflies and amphibians have severely declined since the 1970s. This provides evidence of substantial deterioration of the Camargue ecosystem…

Biologists investigate mass die-of freshwater mussels


Photograph: © SAF — Coastal Care

Excerpts;

Freshwater mussels, like pollinators and trees, are critical to their larger ecosystems and the world around them. They create habitat for other species, like freshwater coral reefs, and help maintain the structure and rigidity of the waterways they call home. They scoop up algae and nutrients, processing and concentrating them for others to eat.

But perhaps most importantly, these soft-bodied invertebrates improve the water quality around them. They filter out sediment and agricultural runoff, limiting the size and impacts of dead zones…
