Anthropoceneand and Its Effect on Ecosystem
摘要/Abstract
介绍了“人类世”是一个全新的地质时期，由人类对生态系统的影响所定义，这个时代的开始时间尚未正式确定，但科学家已经达成共识，地球已经进入“人类世”.人类活动导致地球的“四大生态极限”被突破，生物多样性减少，物种灭绝速率提高；人类活动引起的全球变暖已逆转了过去1 800 a的海洋自然冷却过程，地球升温速度是过去降温速度的20倍.人类对地球的过度开发使“地球生态超载日”到来时间逐年提前，说明人类消耗资源的速度超过了地球的再生能力.这意味着人类必须认识到已经对生态环境造成了灾难性的改变，需要采取紧急措施捍卫地球的未来.中国已经采取了积极的举措，并承诺在2030年实现“碳达峰”，在2060年实现“碳中和”.全球各国应该共同努力，减少对环境的影响，推迟“地球生态超载日”的到来，实现可持续发展和人与自然的和谐共生.
This paper introduces the concept of the "Anthropocene" as a new geological epoch defined by the impact of human activities on the ecosystem.While the official start date of this era is yet to be determined,scientists have reached a consensus that the earth has entered the Anthropocene.Human activities have led to the crossing of the "four planetary boundaries", resulting in reduced biodiversity and an increased rate of species extinction.Global warming caused by human activities has reversed the natural ocean cooling process of the past 1 800 years,with the earth warming at a rate 20 times faster than the previous cooling rate.Human overexploitation of the earth has led to an increasingly earlier "Earth Overshoot Day",indicating that the rate at which humans consume resources exceeds the earth′s regenerative capacity.This suggests that humans must recognize the catastrophic changes we have caused to the ecosystem and take urgent action to defend the future of the earth.China has taken proactive meas
