过去的大灭绝事件是由环境的灾难性变化引起的,包括大规模的火山爆发或小行星撞击地球。而如今正在发生的第六次物种大灭绝则不同:科学家表示,这次大灭绝是由人类引起的。
"It is entirely our fault," Ceballos González said.
“这完全是人类的错”,塞巴罗斯·冈萨雷斯说。
While life on Earth has bounced back after each of these events, it took millions of years to restore the number of species.
虽然地球上的生命在每一次大灭绝事件后都有所恢复,但物种数量的恢复却要花费数百万年的时间。
"Even though only an estimated 2% of all of the species that ever lived are alive today, the absolute number of species is greater now than ever before," the scientists said. "It was into such a biologically diverse world that we humans evolved, and such a world that we are destroying."
科学家们说:“尽管在所有曾经存在过的物种中,估计只有2%存活至今,但现在物种的绝对数量比以往任何时候都要多。我们人类就是在这样一个生物多样性的世界里进化而来的,而我们正在摧毁这样一个世界。”
Ceballos González and his colleagues said many of the species that are on the brink of extinction are concentrated in the same regions being decimated by human impacts.
塞巴罗斯·冈萨雷斯和他的同事说,许多濒临灭绝的物种都集中在被人类破坏的相同地区。
