Climate change imperils one in four natural heritage sites: report

Climate change imperils one in four natural World Heritage sites, including coral reefs, glaciers, and wetlands—nearly double the number from just three years ago, a report said Monday…

The number of sites at risk has grown to 62 from 35 in 2014, when one in seven were listed, according to the International Union for Conservation of Nature (IUCN), which released the report at UN climate talks in Bonn, Germany.

Among the ecosystems most threatened by global warming are coral reefs which bleach as oceans heat up, and glaciers which melt…

Humans have never eaten so much fish and other seafood, but nearly half of it is no longer caught wild but is grown in farms, says the United Nations. The rapid growth in the number of people living near coasts and fish farming’s ability to keep up with population growth has seen per capita fish consumption soar from 10kg per person in the 1960s to more than 19kg in 2012…

Excerpts;

“There’s a new front in President Trump’s war on our environment: Alaska’s spectacular Bristol Bay. The Trump administration cut a backroom deal with a foreign mining company to bring the toxic gold and copper Pebble Mine back from the dead. And if we don’t stop them, the resulting pollution and environmental destruction would be a catastrophe for the wildlife and communities that call Bristol Bay home.” —NRDC

Excerpts;

The significant scale of human impact on our planet has changed the course of Earth history, an international team of scientists led by the University of Leicester has suggested.

Rapid changes to the planet include acceleration of rates of erosion and sedimentation; large-scale chemical perturbations to the cycles of carbon, nitrogen, phosphorus and other elements; the inception of significant change to global climate and sea level; and biotic changes including unprecedented levels of species invasions across the Earth…

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.
