美国航空航天局近期对地下含水层进行了详细评估,证实了长期以来科学家的怀疑,即人类超支使用地下含水层。根据实验卫星GRACE的反馈,全球37个最大含水层中的21个,水位已经下降到可持续性临界点,它们位于中国、印度、法国和北非等地。研究人员说,随着人类越来越依赖地下水,地下含水层的恢复速度难以跟上农业、人口增长和工业用水需求增长,问题会越来越严重。 NASA recently conducted a detailed assessment of the aquifers underground, confirming the long-suspected scientists suspicion that the use of underground aquifers for human over-expenditures. Based on feedback from the experimental satellite GRACE, 21 of the 37 largest aquifers in the world have dropped to the critical point of sustainability in China, India, France and North Africa. The researchers say the problem will be aggravated as humans become increasingly reliant on groundwater, recovering underground aquifers hard to keep up with agriculture, increasing population and growing demand for industrial water.
