Oil Palms Behind the Green Curtain, Explained

A curtain of green, with a few birds, looks almost intact. "And beyond that strip, there is nothing but regimented rows of oil palms." The dizzying mix of rainforest trees has been replaced by one crop, and the calm green is only a half-mile strip hiding the rows.

Oil Palms Behind the Green Curtain, explained

What happens

The narration moves through a tropical rainforest where orangutan mothers spend ten years teaching their young which fruits are worth eating. A small patch may hold 700 tree species, as many as in North America. That mix is turned into a monoculture of oil palm. A curtain of green looks perhaps okay from the ground, but a helicopter shows a strip half a mile wide and regimented rows beyond.

What's really going on

On the ground a curtain of green with a few birds can pass for forest. "and you think it's perhaps okay." A helicopter shows the trick: "that is a strip about half a mile wide," and "beyond that strip, there is nothing but regimented rows of oil palms." Orangutan mothers spend ten years teaching their young which fruits are worth eating. Without that, "they would not complete their role in dispersing seeds," and "The future generations of many tree species would be at risk." What replaced that diversity is blunt: "A monoculture of oil palm. A habitat that is dead in comparison." Cutting pays twice, timber and then the land left behind, which is why "we've cut down three trillion trees" and half the rainforests "have already been cleared." The orangutan population on Borneo is down by two-thirds since that first sight. The close is plain: "anything that we can't do forever is by definition unsustainable," until damage hits "a point where the whole system collapses."

Key lines & what they mean

“Orangutan mothers have to spend ten years with their young, teaching them which fruits are worth eating.”
Orangutan mothers stay with their young for ten years to teach them which fruits are worth eating.
“And yet, this is what we've been turning this dizzying diversity into.”
The dizzying mix of tree species is being turned into the single oil-palm crop shown next.
“And beyond that strip, there is nothing but regimented rows of oil palms.”
Beyond the strip, there is nothing left except oil palms planted in orderly, repeating rows.
“What we see happening today is just the latest chapter in a global process spanning millennia.”
What is happening now is only the newest part of a worldwide clearing that has already gone on for thousands of years.
“The deforestation of Borneo has reduced the population of orangutan by two-thirds since I first saw one just over 60 years ago.”
Borneo's deforestation has cut the orangutan population by two-thirds since the speaker first saw one, a little more than sixty years ago.
“We can't cut down rainforests forever, and anything that we can't do forever is by definition unsustainable.”
Rainforests cannot be cut down without end, and the line says that very limit is what unsustainable means.

Theme

  • Survival — Half the world's rainforests are already cleared, and the damage is said to accumulate until the whole system collapses.
  • Generations — Orangutan mothers spend ten years teaching their young, because without that the future generations of many tree species would be at risk.

Questions, then the lines
Why does the green look all right from the ground?

The view is a curtain of green with occasional birds, and the narration says you think it's perhaps okay. From a helicopter that curtain is a strip about half a mile wide, with nothing but regimented rows of oil palms beyond it.

Why do orangutan mothers spend ten years with their young?

They are teaching them which fruits are worth eating. Without this training, the young would not complete their role in dispersing seeds, and the future generations of many tree species would be at risk.

Why is there a double incentive to cut down forests?

People benefit from the timber and then benefit again from farming the land left behind. The narration calls that a double incentive to cut the forests down.

What has the dizzying diversity been turned into?

A monoculture of oil palm, called a habitat that is dead in comparison. The patch it replaces could hold 700 tree species, as many as there are in the whole of North America.
