相比之下,在野外生活的狮子只剩下20000只,猎豹只有不到7000只,大熊猫只剩下500到1000只,苏门答腊犀牛也只有250头左右。
罪魁祸首
The main drivers of wildlife decline are habitat loss, overconsumption, pollution, invasive species, disease, as well as poaching in the case of tigers, elephants, rhinos and other large animals prized for their body parts.
野生动物减少的主要原因有:失去栖息地、人类过度消耗、环境污染、物种入侵、感染疾病以及偷猎活动(因为老虎、大象、犀牛以及其他大型动物的一些身体部位价值连城)。
Climate change is poised to become a major threat in the coming decades, with some animals - most famously polar bears - already in decline due to rising temperatures and changing weather patterns.
气候变化在未来的几十年将成为生物灭绝的主要威胁因素。由于气温升高,天气模式变化,一些动物——比如最著名的北极熊——已经减少。
"The massive loss of populations and species reflects our lack of empathy to all the wild species that have been our companions since our origins," said lead author Gerardo Ceballos of the National Autonomous University of Mexico.
“野生动物自古是人类的朋友,从数量和物种的大幅下降可以看出,我们缺少对这些动物的怜悯之情,”墨西哥国立自治大学的首席作者热拉尔多•塞巴洛斯说。
