Humanity has a long history of working together to hunt large prey.
As evidence, see the extinction rates of large animals after people first arrive in a new locale.
Now scientists have a clearer view of our predatory role, across a number of terrestrial and marine ecosystems.
And the picture is not a pretty one—we have some bad hunting habits.
Researchers surveyed 2,125 species of predators on land and in the water.
And they compared the behavior of nonhuman predators to humans in those ecosystems.
Perhaps not surprisingly,humans prey on important large carnivores at a dramatically higher rate than other predators do.
The biggest difference, however, comes in which members of the population we cull.
Typical predators might kill the young or the infirm.
Humans, both on land and particularly in the water, claim a disproportionate number of mature healthy adults of reproductive age.
This practice has dramatic consequences.
Removing reproductive adults, especially for species that mature slowly, can do long-term damage to the entire population.
The authors thus call humans “super-predators.”
Their report is in the journal Science.
They write that options to encourage more sustainable exploitation could include reducing the take-but also mimicking other predators and leaving full-grown adults alone to continue repopulating their habitats.

很久一段时间以来人类一直通过合作的方式猎杀大型猎物Ze(5[1ST7%EeARH。

现在科学家们对我们人类在一系列陆地及海洋生态系统中掠夺成性的本性已经有清楚的认知zwwn,boA0qU9Pyt@V5nH。
但这种认知不是特别美好—这是因为我们本身具备的肆意猎杀习性所致Ja*Z7,rr+IGG.)C11]YR。
研究者们对陆地及海洋中的2225种猎食者进行了调查Z1NLkl.uHTvD12。

而且他们将生态系统中这些非人类的捕食者的行为同人类进行比较N+1^0I4Mba0hG48*。
也许结果并不令人称奇，与其他捕食动物相比，人类对于重要大型食肉动物的猎杀比例要高很多~dE;A)&hZo5xy[olGy*。
但最大的区别在于我们人类所猎杀的数量Q[&KhuDp..Mj3。
捕食动物们一般会猎杀年幼或体弱多病者Eo6z3v~kZrT*.osb.5Hm。
反观人类方面，陆地，特别是在水中的猎物全部通吃，而且猎杀的是不成比例能够繁殖下一代的健康成年个体dT~zW5@1zv4J_pRU(。
