Human activities have caused the world's wildlife populations to plummet by more than two-thirds in the last 50 years, according to a new report from the World Wildlife Fund. 根据世界野生动物基金会的一份新报告，在过去的50年里，人类活动已经导致世界野生动物数量下降了三分之二以上。 The decline is happening at an unprecedented rate, the report warns, and it threatens human life as well. 报告警告说，这种减少的速度是前所未有的，而且已经威胁着人类的生命。  "The findings are clear," the report states. "Our relationship with nature is broken." “研究结果很清楚，”报告称。“我们与自然的关系很糟糕。” The Living Planet Report 2020 report drew on wildlife monitoring of more than 4,300 different vertebrate species - animals, fish, birds and amphibians - from around the world. It found that population sizes for those monitored species declined by an average of 68 percent from 1970 to 2016. 《地球生命力报告2020》报告对来自世界各地的4300多种脊椎动物——动物、鱼类、鸟类和两栖动物——进行了野生动物监测。研究发现，从1970年到2016年，受监控物种的种群规模平均下降了68%。  In the American tropics, including the Caribbean and Latin America, population sizes decreased by a staggering 94 percent. 在美洲热带地区，包括加勒比和拉丁美洲，野生物种规模惊人地减少了94%。 Forest clearing for agricultural space was the predominant cause of the decline, the report says, noting that one-third of the planet's land is currently being used for food production. 该报告指出，为农业用地而砍伐森林是人口减少的主要原因，并指出目前地球上三分之一的土地都已经用于了粮食生产。 Human-caused climate change is another growing driver. 人类造成的气候变化是另一个日益增长的原因。  "We can't ignore the evidence – these serious declines in wildlife species populations are an indicator that nature is unraveling and that our planet is flashing red warning signs of systems failure," wrote Marco Lambertini, Director General of World Wildlife Fund International. “我们不能忽视证据——野生动物种群数量的严重减少是大自然正在解体的一个信号，我们的星球正在闪烁着系统失灵的红色预警信号，”世界野生动物基金会的总干事马克·朗伯提尼写道。 问题 文中提到目前地球上有多少土地用于了粮食生产呢？ 留言回复正确答案，前十名朋友可以获得红包奖励哦，赶快来试试吧！ 感谢关注 跟amber一起看世界 |
