Overexploitation

http://biodiversity.europa.eu/topics/overexploitationThe unsustainable use of natural resources and overexploitation, which occurs when harvesting exceeds reproduction of wild plant and animal species, continues to be a major threat to biodiversity.
The ecological footprint analysis compares human demands on nature with the biosphere's ability to regenerate resources and maintain ecosystem services. It does this by assessing the biologically productive land and marine area required to produce the resources consumed and to absorb the corresponding waste, using available technology. Overall biological resources use and waste emission is well above the biological capacity available within Europe, showing that the continent cannot sustainably meet its consumption demands within its own borders. The EU-27 on its own has an ecological footprint of 4.7 global hectares per person, twice the size of its biocapacity. Europe’s high per capita consumption and waste production means that its impact also extends well beyond its borders.
