Posted Fri Sep 17 2010: from PLOS-One, through DesdemonaDespair:
Bottom trawling more damaging to sea floor than all other human activities combined
Scientists have for the first time estimated the physical footprint of human activities on the deep seafloor of the North East Atlantic. The findings published in the journal PLoS ONE reveal that the area disturbed by bottom trawling commercial fishing fleets exceeds the combined physical footprint of other major human activities considered.... Using available data for the year 2005, they mapped and estimated the spatial extent of intentional human activities occurring directly on the seafloor as well as structures and artefacts present on the seafloor resulting from past activities.... Even on the lowest estimates, the spatial extent of bottom trawling is at least ten times that for the other activities assessed, with a physical footprint greater than that of all the others combined.
