Scientists Pinpoint How Ocean Acidification Weakens Coral Skeletons

Excerpts;

The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. A new study identifies the details of how ocean acidification affects coral skeletons, allowing scientists to predict more precisely where corals will be more vulnerable.

Corals grow their skeletons upward toward sunlight and also thicken them to reinforce them.
The new research, led by scientists at Woods Hole Oceanographic Institution (WHOI), shows that ocean acidification particularly impedes the thickening process—decreasing the skeletons’ density and leaving them more vulnerable to breaking…

Excerpts;

Every year the French Riviera town of Cannes rolls out the red carpet to A-list celebrities at the world’s most glamorous film festival. Now it wants to roll out a bigger beach too.

The Mediterranean resort is shipping in 80,000 cubic meters of white sand – enough to fill 32 Olympic swimming pools – to widen the beach along a 1.4 kilometer (0.9 mile) stretch of seafront beside the famed “Croisette” promenade…

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.

Excerpts;

Chile has created five sprawling national parks to preserve vast tracts of Patagonia.

The five parks, spanning 10.3m acres, were signed into law on Monday by Chile’s president Michelle Bachelet, launching a new 17-park route that stretches down the southern spine of Chile to Cape Horn.

The creation of the parks marks the latest in a flurry of environmental protection laws which have brought Chile to the forefront of worldwide conservation efforts.

Last month, Bachelet – who leaves office in March – completed a five-year negotiation with residents of Easter Island to form one of the world’s largest Marine Protected areas, which will protect some 720,000 sq km of the Pacific Ocean…
