The giraffe, the tallest land animal, is now at risk of extinction, biologists say.
Because the giraffe population has shrunk nearly 40 percent in just 30 years, scientists put it on the official watch list of threatened and endangered species worldwide, calling it “vulnerable.” That is two steps up the danger ladder from its previous designation of being a species of least concern.
In 1985, there were between 151,000 and 163,000 giraffes, but last year, the number fell to 97,562, the International Union for the Conservation of Nature (IUCN) said.

At a biodiversity meeting on Wednesday in Mexico, the IUCN increased the threat level for 35 species and lowered the threat level for seven species on its “Red List” of threatened species, considered by scientists the official list of what animals and plants are in danger of disappearing.
The giraffe is the only mammal whose status changed on the list this year. Scientists blame habitat loss.
While everyone worries about elephants, Earth has four times as many pachyderms as giraffes, said Julian Fennessy and Noelle Kumpel, cochairs of the specialty group of biologists that put the giraffe on the IUCN Red List.
“Everyone assumes giraffes are everywhere,” said Fennessy, co-director of the Giraffe Conservation Foundation.
However, they are not, he said.
Until recently, biologists had not done a good job assessing giraffe numbers and where they can be found, and they have been lumped into one broad species instead of nine separate subspecies.
“There’s a strong tendency to think that familiar species [such as giraffes and chimps] must be OK because they are familiar and we see them in zoos,” said Duke University conservation biologist Stuart Pimm, who was not part of the work and has criticized the IUCN for not putting enough species on the threat list. “This is dangerous.”
Fennessy blamed shrinking living space as the main culprit in the declining giraffe population, worsened by poaching and disease.
People are moving into giraffe areas especially in central and eastern Africa. Giraffe numbers are plunging most in central and eastern Africa, and are being offset by increases in southern Africa, he said.
This has fragmented giraffe populations, making them shrink in size with wild giraffes gone from seven countries — Burkina Faso, Eritrea, Guinea, Malawi, Mauritania, Nigeria and Senegal, said Kumpel of the Zoological Society of London.
The IUCN says 860 plant and animal species are extinct, and another 68 are extinct in the wild. Nearly 13,000 are endangered or critically endangered. The next level is vulnerable, where giraffes were placed, followed by near threatened and least concerned.
JAN. 1 CLAUSE: As military service is voluntary, applications for permission to stay abroad for over three months for men up to age 45 must, in principle, be granted A little-noticed clause in sweeping changes to Germany’s military service policy has triggered an uproar after it emerged that the law requires men aged up to 45 to get permission from the armed forces before any significant stay abroad, even in peacetime. The legislation, which went into effect on Jan. 1 aims to bolster the military and demands all 18-year-old men fill out a questionnaire to gauge their suitability to serve in the armed forces, but stops short of conscription. If the “modernized” model fails to pull in enough recruits, parliament will be compelled to discuss the reintroduction of compulsory service, German
PHISHING: The con might appear convincing, as the scam e-mails can coincide with genuine messages from Apple saying you have run out of storage For a while you have been getting messages from Apple saying “your iCloud storage is full.” They say you have exceeded your storage plan, so documents are no longer being backed up, and photos you take are not being uploaded. You have been resisting Apple’s efforts to get you to pay a minimum of ￡0.99 (US$1.33) a month for more storage, but it seems that you cannot keep putting off the inevitable: You have received an e-mail which says your iCloud account has been blocked, and your photos and videos would be deleted very soon. To keep them you need
For two decades, researchers observed members of the Ngogo chimpanzee group of Kibale National Park in Uganda spend their days eating fruits and leaves, resting, traveling and grooming in their tropical rainforest abode, but this stable community then fractured and descended into years of deadly violence. The researchers are now describing the first clearly documented example of a group of wild chimpanzees splitting into two separate factions, with one launching a series of coordinated attacks against the other. Adult males and infants were targeted, with 28 deaths. “Biting, pounding the victim with their hands, dragging them, kicking them — mostly adult males,
Filipino farmers like Romeo Wagayan have been left with little choice but to let their vegetables rot in the field rather than sell them at a loss, as rising oil prices linked to the Iran war drive up the cost of harvesting, labor and transport. “There’s nothing we can do,” said Wagayan, a 57-year old vegetable farmer in the northern Philippine province of Benguet. “If we harvest it, our losses only increase because of labor, transportation and packing costs. We don’t earn anything from it. That’s why we decided not to harvest at all,” he said. Soaring costs caused by the Middle East
