In 1961, according to the network, humankind used onlyabout three-quarters of Earth's annual resource allotment. By the 1970s, economicand population growth sent Earth into annual overshoot.
根据Global Footprint Network所说,1961年,人类一年只用了四分之三的自然资源配额。而到了20世纪70年代,经济和人口增长把地球推到了年度的自然资源超支。
"This is possible because we emit more carbondioxide into the atmosphere than our oceans and forests can absorb, and wedeplete fisheries and harvest forests more quickly than they can reproduce andregrow," the network said in a statement.
Global Footprint Network在一份声明中说到:“这是有可能的,因为我们向大气中排放更多的二氧化碳,而海洋和森林无法全部吸收,我们消耗渔牧业所得的速度也超过了它们生产繁殖的速度。”
To calculatethe date for Earth Overshoot Day, the group crunches UN data on thousands ofeconomic sectors such as fisheries, forestry, transport and energy production.
为了计算出地球超支日的具体日期,联合国数据组研究了成千上万的数据,比如渔业、林业、交通和能源生产。
Earth-warming greenhouse gas emissions, it said, arenow the fastest-growing contributor to ecological overshoot, making up 60percent of humanity's demands on nature .
