Terrestrial ecoregions of North America: a conservation assessment. Ricketts, Taylor H., Eric Dinerstein, David M. But worse, it has been estimated that as many as 16,000 species are in grave danger of extinction. The eternal frontier: an ecological history of North America and its peoples. This means that 1.7 planets were needed to cover the needs of humans. According to the Global Footprint Network, in 2016 the global ecological footprint was 2.7 hag for a biocapacity of 1.6 hag. By 1999, nearly 1,200 native North American species had been placed on the official endangered list. Not all countries exert the same pressure on the Earth and the ecological footprint of a country is calculated from the ecological footprint of its inhabitants. They had won a great victory in the war and had created one of the most affluent and self-contented societies, yet still the pillage of their natural resources was not finished. By the 1950s, North Americans had destroyed about four-fifths of the continent's wildlife, cut more than half its timber, all but destroyed its native cultures, dammed most of its rivers, obliterated its most productive freshwater fisheries and depleted a good proportion of its soils. In a biological sense, the over-exploitation of the frontier was akin to going out in a blaze of glory.
