[翻译]SCIENCE IN THE NEWS - More than Half of the World’s Primates Disappearing

Scientists who study primates say that we are moving towards a time when species like gorillas will no longer be found in the wild.


They say Orangutans would be gone too. And Madagascar would lose its lemurs.


Jo Setchell is a primatologist at Durham University in Britain. She studies primates, the group of mammals that includes gorillas, chimps, monkeys, gibbons, mandrills, and lemurs. And, of course, humans.

乔·撒切尔(Jo Setchell)是英国达勒姆大学的灵长类动物学家。她研究灵长类动物,这类哺乳动物包括大猩猩、黑猩猩、猴子、长臂猿、狒狒、狐猴,当然还有人类。

"So If we have 60 percent threatened with extinction at the moment, then we will see that number rise and within our lifetimes, within our children's lifetimes, we will eradicate other primates."


In all, there are an estimated 600 different species of primates. They include the little creature called the mouse lemur, whose body is only about six centimeters long. Then, there is the largest of the species, the gorilla, weighing up to 250 kilograms.


Primates face one common threat: loss of habitat, the places in nature where they live. Primatologists like Setchell say human activity is to blame.


"... the major problem is habitat loss and habitat conversion, and essentially it's humans changing primate habitat into human habitat - logging for timber, logging for conversion to agriculture, logging for cattle ranching; anything essentially that destroys tropical forests because primates are largely tropical forest species."


More than half of all primate species are grouped in four countries: Brazil, Indonesia, Madagascar and the Democratic Republic of Congo.


Paul Garber says each of these countries is working to help protect the primates in their areas. “But often, there is neither the funds, community support nor in-country expertise to address their conservation problems.”

保罗·加伯(Paul Garber)表示,这几个国家都在努力保护境内的灵长类动物。“但是通常他们既没有资金和社区支持,他们国内也没有解决他们自然环境保护问题的专业知识。”

Madagascar is a good example of these problems, he says. It is home to over 100 primate species; almost all of them live nowhere else. And 94 percent of them are endangered. Ninety percent of the original forests of Madagascar have been cut down, Garber says.


Neither Garber nor Setchell have any easy answers about how to stop this road to extinction.


"We knew that primates were in trouble, but I think even for those of us who work in primate conservation, it was still shocking to discover quite what the scale of the problem is."


They do say that the clearest way is to slow human activity in primates’ habitats. They also say the decrease is reversible if humans make primate and habitat conservation a top concern.
