Trade of coastal sand is damaging wildlife of poorer nations, study finds
Wealthy nations’ drastic increase in construction sand consumption contributes to erosion of estuaries
The secretive trade of coastal sand to wealthy countries such as China is seriously damaging the wildlife of poorer nations whose resources are being plundered, according to a new study.
Sand and gravel are the most extracted groups of materials worldwide after water, with sand used in the concrete and asphalt of global cities. China consumed more sand between 2011 and 2013 than the US did during the entire 20th century. India has more than tripled its annual use of construction sand since 2000.

Pollutionwatch: summer's deadly wildfires cause pollution worldwide
Widespread wildfires have taken lives and destroyed habitats as well as causing air pollution
Wildfires are spanning the northern hemisphere. Local impacts have been severe; notably the loss of habitat and life, including the tragic deaths in Greece. Smoke has caused air pollution problems in nearby cities, exposing millions of people. Moorland fires affected air pollution in Manchester. Cities on the west coast of the US and Canada, including Seattle and Vancouver, issued pollution alerts as forest fire smoke turned day into night. During a national league soccer game in Oregon players had breaks every 15 minutes and oxygen was provided for them. But the smoke spreads further. Smoke from Siberian forest fires crossed the Arctic to reach North America in July . Weather models and satellite pictures showed that smoke from North American forest fires crossed the Atlantic in the high atmosphere and reached Europe in mid-August, causing purple skies in southern Ireland.
A study in 2011 estimated that between 260,000 and 600,000 early deaths were attributable to air pollution from landscape fires each year. The annual toll normally varies with the La Niña/El Niño cycle that causes yearly variations in global weather. The effects of this year’s fires have yet to be estimated.

Crop losses to pests will soar as climate warms, study warns
Rising temperatures make insects eat and breed more, leading to food losses growing world population cannot afford, say scientists
Rising global temperatures mean pests will devour far more of the world’s crops, according to the first global analysis of the subject, even if climate change is restricted to the international target of 2C.
Increasing heat boosts both the number and appetite of insects, and researchers project they will destroy almost 50% more wheat than they do today with a 2C rise, and 30% more maize. Rice, the third key staple, is less affected as it is grown in the tropics, which are already near the optimal temperature for insects – although bugs will still eat 20% more.
