在印度、中国、美国等地，地下含水层被抽离的速度比自然补给还要快。
Groundwater aquifers are being pumped down faster than they are naturally replenished in parts of India, China, the USA and elsewhere.
地下水的渗透速度影响着其与岩石的反应速度，而地质构造、岩层厚度、岩石破碎程度及地下水的补给状况等则是影响地下水运动的重要因素。
Infiltration velocity of groundwater influences its reaction rates with rocks. Geological structure, strata depth, rupture degree and supply of groundwater are major influence factors.
尽管如此，由于运输船大多是小型运输船，所以补给的速度仍然跟不上。
Nevertheless, as carriers are small carriers, the supply still can not keep up the pace.
我们过度使用自然资源，速度太快以致于来不及补给和回报，或者让自然去自行恢复。
We have been using up the world's natural resources quicker than we can replenish and give back to it, or let itself regenerate.
