Environment Minister Matt Kean said the plan is to help fight against, what he called, the worst extinction rate of mammals in the world.

环境部长马特·基恩表示，这项计划是为了帮助对抗他所说的全球最严重的哺乳动物灭绝率。

We are in the midst of the sixth mass extinction, and the extinction rate is up to 10,000 times faster than what is considered normal.

我们正处于第六次大规模灭绝之中，它的灭绝速度比我们认为的正常速度快了10，000倍。

Thanks to our unstable practices, the world's wildlife is inching towards an extinction rate that's 10,000 times faster than what is considered to be natural.

由于我们不稳定的活动，世界上的野生动物正在慢慢向一个以比自然情况下快一万倍的灭绝速度前进。

In other words, human interaction has accelerated the extinction rate by over 100 times—a rate comparable to the Big Five.

换句话说，人类互动使灭绝速度加快了 100 多倍——与五巨头相当。

Study author Samuel Bowring from M.I.T. says they can't yet compare the speed of the previous extinction to the extinction rates caused by human activities today.

此项研究的作者来自于麻省理工学院的萨穆埃尔博文称他们仍不能将之前灭绝事件发生的速度与人类现今的活动导致的物种灭亡速度相比较。

The current rate of biodiversity loss is hundreds of times higher than the natural extinction rate, leading scientists to declare a sixth mass extinction.

目前生物多样性丧失的速度比自然灭绝的速度高出数百倍，导致科学家宣布第六次大规模灭绝。

To qualify as a mass extinction, an event must eradicate at least half of the species on our planet, resulting in a significant elevation of the extinction rate.

要构成大规模灭绝，一个事件必须消灭地球上至少一半的物种，从而导致灭绝率显着提高。
