Chopping down Australia

Australia has a rich biodiversity, with nearly 8% of all Earth’s plant and animal species finding a home on the continent. About 85% of the country’s plants, 84% of its mammals and 45% of its birds are found nowhere else.
But land clearing is putting that at risk. About three-quarters of Australia’s 1,640 plants and animals listed by the government as threatened have habitat loss listed as one of their main threats.
Projections suggest that in the two decades to 2030, 3m hectares of untouched forest will have been bulldozed in eastern Australia. In Queensland, where there is both the most clearing and the best data on clearing, trees are being bulldozed at a phenomenal rate.
About 395,000 hectares of native vegetation were cleared there in 2015-16, 33% more compared with the previous year. And despite the re-elected Labor government promising changes to rein it in, notifications of planned land clearing in Queensland have jumped a further 30%, suggesting woodlands could be bulldozed even faster in coming years.
Queensland clears more land each year than the rest of Australia put together, and the rate at which it is destroying its vegetation is comparable with the infamous deforestation that occurs in the Brazilian Amazon. Brazil bulldozes about 0.25% of its part of the Amazon each year; Queensland clears about 0.45% of its remaining wooded areas.
Meanwhile, further north, vast tracts of land are being earmarked for clearing. In the relatively lawless Northern Territory, approvals for land clearing have  in the past two years, compared with the preceding 12 years. A property called Tipperary station has a total of 50,687 hectares approved for clearing through a number of separate applications over the past six years, an area almost 10 times the size of Manhattan on one property.
The crisis is driven primarily by a booming livestock industry but is ushered in by governments that fail to introduce restrictions and refuse to apply existing restrictions.
In 1990, before short-lived land-clearing controls came into place, a quarter of Australia’s total greenhouse gas emissions were caused by deforestation. Emissions from land clearing dropped after 2010 but are rising sharply again.
