Palm oil frenzy threatens to wipe out orangutans

? Hoping to unravel the mysteries of human origin, anthropologist Louis Leakey sent three young women to Africa and Asia to study our closest relatives: It was chimpanzees for Jane Goodall, mountain gorillas for Dian Fossey and the elusive, solitary orangutans for Birute Mary Galdikas.

Nearly four decades later, 62-year-old Galdikas, the least famous of his “angels,” is the only one still at it. And the red apes she studies in Indonesia are on the verge of extinction because forests are being clear-cut and burned to make way for lucrative palm oil plantations.

Galdikas worries many questions may never be answered. How long do orangutans live in the wild? How far do the males roam? And how many mates do they have in their lifetime?

“I try not to get depressed, I try not to get burned out,” says the Canadian scientist, pulling a wide-rimmed jungle hat over her shoulder-length gray hair in Tanjung Puting National Park. She gently leans over to pick up a tiny orangutan, orphaned when his mother was caught raiding crops.

“But when you get up in the air you start gasping in horror; there’s nothing but palm oil in an area that used to be plush rain forest. Elsewhere, there’s burned-out land, which now extends even within the borders of the park.”

The demand for palm oil is rising in the U.S. and Europe because it is touted as a “clean” alternative to fuel. Indonesia is the world’s top producer of palm oil, and prices have jumped by almost 70 percent in the last year.

But palm oil plantations devastate the forest and create a monoculture on the land, in which orangutans cannot survive. Over the years, Galdikas has fought off loggers, poachers and miners, but nothing has posed as great a threat to her “babies” as palm oil.

There are only an estimated 50,000 to 60,000 orangutans left in the wild, 90 percent of them in Indonesia, said Serge Wich, a scientist at the Great Ape Trust of Iowa. Most live in small, scattered populations that cannot take the onslaught on the forests much longer.

Trees are being cut at a rate of 300 football fields every hour. And massive land-clearing fires have turned the country into one of the top emitters of carbon.
