Srminario: Mining and destruction of glaciers in Chile
On Monday 1 December, a colleague friend of mine who worked for a few years in u. of Waterloo, Canada, will present a lecture on the scientific basis for a policy that protects the glaciers ... shall refer to the gradual destruction of the so-called "rock glaciers" that have been overlooked in politics, and they are absolutely unknown to the public (because its morphology apparent color and not for common glaciers) but represent large reservoirs of water. Those who have known usufruct if the water available in the aforementioned mining glaciers have been ... many of them have not even mentioned their use or simply the dismantling when they had to respond environmentally ... will mñana at 11:00 hrs in the auditorium of the Academy of Christian humanism.
Greetings and hope you spread this invitation

Seminar: Mining and destruction of glaciers in Chile
Alexander Brenning, University of Waterloo will lead a discussion on the impact of mining on these reserves Frozen Water: Monday December 1 at 11 am in U. Academy Christian Humanism in Santiago.Sea by removal of rock glaciers, by deposition of waste rock over them or construction of roads, between 2000 and 2006 the mining company Pelambres (MLP) has affected permanent reservoirs of fossil water equivalent to a maximum 2.84 million cubic meters of this vital, loss according to a study by the University of Waterloo, was produced by interventions "is not announced by any of the environmental studies submitted to the authority between 1997 and 2004." Dated 1 October, the report by the geographer Alexander Brenning Canadian and Chilean Guillermo Azocar, emphasizes that "interventions" of the action occurring in an area of \u200b\u200bhigh solar radiation and low rainfall in the Region of Coquimbo, where, incidentally, the value of water is even more sensitive. "The removal or alteration of rock glaciers in semi-arid areas involves the loss of important natural reservoirs of fossil water in a frozen state," says the document, adding that, as in the area where it is located Pelambres no conventional or white glaciers, " rock glaciers and permafrost in the mountains are the only permanent ice reservoirs in this area and, therefore, of critical importance to the hydrological system. " The results of the report were obtained through a study of satellite photos taken from various sources in 1997, 2000 and 2006, which identified that of the 15 rock glaciers in the environment of the mine, four "have almost completely disappeared by the advance of sterile material dumps, "and two" have only been operated by the construction of roads, degraded in total an area of \u200b\u200bbetween 0.11 and 0.14 square killómetros rocky resort comprising between 40% and 60% ice . The study charges that mining Pelambres announced no action of these few glaciers studied, even though they "knew of its existence" because in 1998 it commissioned the consultant Geoestudios "Identification and evaluation of all rock glaciers" in the area of \u200b\u200bthe Region of Coquimbo. "Because we do not know this information was omitted in subsequent studies, therefore, in our view, do not have the approval from environmental authorities and industry." But Alexander Brenning tests are not limited to the Luksic Group company, for in your next visit to Chile, also expose the damage caused by Codelco, Disputada de Las Condes, and other firms that dynamite the ice to dig minerals underneath.
