Coal has completely transformed the landscape in Central Appalachia . This region ’s rich chronicle of coal miningdates back to the 18th century . airfoil minelaying , however , is a more “ modern ” signifier of extracting the dirty fuel source that require clearing timberland and sometimes fumble up mass to reach the ample coal underneath .
A newstudyout Wednesday in PLOS ONE maps how these mines have converted the region ’s mountainous lush forests into desolate landscape of destruction .
From 1976 to 2015 , striptease excavation and mountaintop removal contributed to wiping out about 1.5 million acres of timber across 74 counties in Kentucky , Tennessee , Virginia , and West Virginia . For reference , that ’s three times the size of the Great Smoky Mountains National Park .
The study was authored by researcher from Duke University as well as SkyTruth and Appalachian Voices , environmental nonprofit organization that oppose airfoil excavation . They conduct the field of study by looking at satellite paradigm , identifying active mine by analyzing the normal amount of vegetation in the region and looking for areas where tree cover was low or nonexistent .
Their algorithms excluded any regions that were not within a mine permit boundary and potential to be afforest . They also removed any tiny parcels of land unlikely to be an actual mine . In addition to looking at Din Land use change , they also found that current ember output could help oneself predict the amount of dry land convert into active minelaying five years afterwards by comparing the results with Union mine product datum . For every metric gross ton of coal a company produces , roughly 129 straight foot are mined . This is a dramatic addition compared to the less than 10 straight substructure ask per every metric ton of coal that a2013 study found .
Given the reliance on satellite images , however , there ’s a chance some non - mine were included because the model could n’t distinguish a universal site with low vegetation from one that ’s in reality a mine . Cloud covering fire also meant they had to ditch some satellite imagery , sum another layer of uncertainty to the analytic thinking .
This new subject area shed light on the way surface mining has change the landscape in an iconic part of the U.S. , which now has valleys higher in elevation and mountain rooftree that are broader and low in elevation , per an analysis in 2013 . This mess with the fashion plants maturate and , well , the fauna that swear on them , too .
Mining also messes with people ’s wellness , too . The region is now handle with a recentuptick of grim lung diseasefrom mining . And then there ’s that wholeclimate change affair .
Coal is n’t the diligence that it used to be withproduction and prices droppingacross the display panel . That has n’t stopped the industry from leach land of its other natural resource , though , as this new study clearly shows . Every time a surface mine is excavated , that imply ecosystems are veer apart , wildlife misplace habitat , and water is menace by befoulment , per the Environmental Protection Agency .
That ’s why these two group behind the study are against mining . Instead of create young mines for this antiquated fuel germ , theysuggestputting coal miners to work reclaiming the give up mine . That ’s one way to go away the wipeout behind for good .
