澳大利亚正面临全球最严重的物种灭绝危机。该国每十年失去约四个物种,官方灭绝物种名单已确认67个物种永久消失,但科学家认为实际数字至少达100种[1]。2019-20年黑夏大火造成约30亿只动物死亡,进一步加剧了生态灾难[1]。栖息地破坏、入侵物种、疾病和气候变化等多重威胁持续威胁澳大利亚的生物多样性[1]。
然而,数袋鼠的成功复兴提供了一线希望[1]。这种濒危动物种群曾在20世纪80年代跌至50只,经过数十年的持续保护,特别是在德兰德拉森林保护区的努力下,种群数量已恢复至约3000只[1]。这一成就得到了国际认可——数袋鼠最近被从国际濒危物种名单中移除,现被列为近危物种[1]。
然而,保护工作面临巨大的资源和政治障碍[1]。澳大利亚联邦政府直接用于自然保护的支出约为7亿澳元,而保护主义者认为所需投入应达330亿澳元,占国内生产总值的1%[1]。研究显示该国每年在开采、密集农业等有害补贴上花费超260亿澳元,远超环保投入[1]。澳大利亚劳工党政府自2022年上台以来承诺不再新增物种灭绝,并将自然保护作为第二届任期的特色工作[1]。环境部长穆雷·瓦特指出"生物多样性正以令人震惊的速度丧失"[1],该国制定了2030年停止并扭转生物多样性丧失的目标[1]。
Australia loses approximately four species every decade [1], with government records confirming 67 species as extinct while scientists believe the true figure reaches at least 100 plant and animal species [1]. The country faces compounding threats from habitat destruction, invasive species, disease, and climate change [1]. The 2019-20 Black Summer bushfires alone killed about 3 billion animals [1], underscoring the scale of ecological crisis facing the nation.
Yet one species provides a rare success story in this bleak landscape. The numbat, once reduced to just 50 individuals in the 1980s, has recovered to approximately 3,000 through sustained conservation efforts at Dryandra Forest [1]. This tenfold increase culminated in the species being removed from the international endangered species list and reclassified as vulnerable [1]. The achievement demonstrates what focused protection can accomplish, though broader systemic challenges remain unaddressed.
Government commitment to wildlife protection falls far short of need. Australia's federal direct spending on nature conservation totals around 700 million Australian dollars, while conservationists argue it should reach 33 billion dollars—equivalent to 1 percent of GDP [1]. More starkly, the country allocates over 26 billion dollars annually to harmful subsidies for mining and intensive agriculture, exceeding conservation spending more than 26-fold [1]. Environment Minister Murray Watt acknowledged that "biodiversity is being lost at an alarming rate" [1]. The Labor government, which took office in 2022, has committed to preventing further species extinctions and aims to stop and reverse biodiversity loss by 2030 [1].
