Now, the system may gradually -- under pressure of climate change, erosion, biodiversity loss -- lose the depth of the cup, the resilience, but appear to be healthy and appear to suddenly, under a threshold, be tipping over. Upff.
现在，系统逐渐地-- 受到气候变化， 侵蚀，生物多样性丧失的压力-- 于是杯子的深度开始减少，也就是系统适应能力降低， 但似乎是健康的 也似乎是突然间，经过一个槛后， 又跌落到某一界限下了。哦。
