In the USA, only 40 endangered red wolves remain in the wild, and the population could go extinct within eight years, according to a report released last year by the US Fish and Wildlife Service.

美国鱼类与野生动物局去年公布的数据显示，在美国，濒危的野生红狼仅存40只，或将在8年内灭绝。

Earth "is now in the midst of its sixth mass extinction of plants and animals – the sixth wave of extinctions in the past half-billion years," according to the Center for Biological Diversity.

根据美国生物多样性中心的说法，地球“现在处于过去5亿年中的第6次动植物大灭绝时期”。

The group said, "We're currently experiencing the worst spate of species die-offs since the loss of the dinosaurs 65 million years ago.

该组织认为，“自6500万年前恐龙灭绝以来，我们正经历着最严重的物种大灭绝。”

"Although extinction is a natural phenomenon, it occurs at a natural 'background' rate of about one to five species per year. Scientists estimate we're now losing species at 1,000 to 10,000 times the background rate."
