One million species risk extinction due to humans: draft UN report

  • Biodiversity loss and global warming are closely linked, according to the 44-page Summary for Policy Makers
  • Delegates from 130 nations meeting in Paris from April 29 will vet the executive summary line-by-line

PARIS: Up to one million species face extinction due to human influence, according to a draft UN report obtained by AFP that painstakingly catalogues how humanity has undermined the natural resources upon which its very survival depends.
The accelerating loss of clean air, drinkable water, CO2-absorbing forests, pollinating insects, protein-rich fish and storm-blocking mangroves — to name but a few of the dwindling services rendered by Nature — poses no less of a threat than climate change, says the report, set to be unveiled May 6.
Indeed, biodiversity loss and global warming are closely linked, according to the 44-page Summary for Policy Makers, which distills a 1,800-page UN assessment of scientific literature on the state of Nature.
Delegates from 130 nations meeting in Paris from April 29 will vet the executive summary line-by-line. Wording may change, but figures lifted from the underlying report cannot be altered.
“We need to recognize that climate change and loss of Nature are equally important, not just for the environment, but as development and economic issues as well,” Robert Watson, chair of the UN-mandated body that compiled the report, said, without divulging its findings.
“The way we produce our food and energy is undermining the regulating services that we get from Nature,” he said, adding that only “transformative change” can stem the damage.
Deforestation and agriculture, including livestock production, account for about a quarter of greenhouse gas emissions, and have wreaked havoc on natural ecosystems as well.
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) report warns of “an imminent rapid acceleration in the global rate of species extinction.”
The pace of loss “is already tens to hundreds of times higher than it has been, on average, over the last 10 million years,” it notes.
“Half-a-million to a million species are projected to be threatened with extinction, many within decades.”
Many experts think a so-called “mass extinction event” — only the sixth in the last half-billion years — is already under way.
The most recent saw the end of the Cretaceous period some 66 million years ago, when a 10-kilometer-wide asteroid strike wiped out most lifeforms.
Scientists estimate that Earth is today home to some eight million distinct species, a majority of them insects.
A quarter of catalogued animal and plant species are already being crowded, eaten or poisoned out of existence.
The drop in sheer numbers is even more dramatic, with wild mammal biomass — their collective weight — down by 82 percent.
Humans and livestock account for more than 95 percent of mammal biomass.
“If we’re going to have a sustainable planet that provides services to communities around the world, we need to change this trajectory in the next ten years, just as we need to do that with climate,” noted WWF chief scientist Rebecca Shaw, formerly a member of the UN scientific bodies for both climate and biodiversity.
The direct causes of species loss, in order of importance, are shrinking habitat and land-use change, hunting for food or illicit trade in body parts, climate change, pollution, and alien species such as rats, mosquitoes and snakes that hitch rides on ships or planes, the report finds.
“There are also two big indirect drivers of biodiversity loss and climate change — the number of people in the world and their growing ability to consume,” said Watson.
Once seen as primarily a future threat to animal and plant life, the disruptive impact of global warming has accelerated.
Shifts in the distribution of species, for example, will likely double if average temperature go up a notch from 1.5 degrees Celsius (2.7 Fahrenheit) to 2C.
So far, the global thermometer has risen 1C compared with mid-19th century levels.
The 2015 Paris Agreement enjoins nations to cap the rise to “well below” 2C. But a landmark UN climate report in October said that would still be enough to boost the intensity and frequency of deadly heatwaves, droughts, floods and storms.
Other findings in the report include:
- Three-quarters of land surfaces, 40 percent of the marine environment, and 50 percent of inland waterways across the globe have been “severely altered.”
- Many of the areas where Nature’s contribution to human wellbeing will be most severely compromised are home to indigenous peoples and the world’s poorest communities that are also vulnerable to climate change.
- More than two billion people rely on wood fuel for energy, four billion rely on natural medicines, and more than 75 percent of global food crops require animal pollination.
- Nearly half of land and marine ecosystems have been profoundly compromised by human interference in the last 50 years.
- Subsidies to fisheries, industrial agriculture, livestock raising, forestry, mining and the production of biofuel or fossil fuel energy encourage waste, inefficiency and over-consumption.
The report cautioned against climate change solutions that may inadvertently harm Nature.
The use, for example, of biofuels combined with “carbon capture and storage” — the sequestration of CO2 released when biofuels are burned — is widely seen as key in the transition to green energy on a global scale.
But the land needed to grow all those biofuel crops may wind up cutting into food production, the expansion of protected areas or reforestation efforts.

Children’s author Judith Kerr, who wrote ‘The Tiger Who Came to Tea’, dies

  • Kerr's family fled Germany as the Nazi's rose to power
  • She based the characters on animals she had seen in real life

LONDON: British writer and illustrator Judith Kerr, whose death at 95 was announced on Thursday, captivated young readers around the world with her tales of a fluffy tiger coming to tea, a trouble-prone cat and her own family's flight from Nazi Germany.
With curly hair and a mischievous smile, the petite Kerr worked well into her 90s, saying she even picked up the pace in old age, drawing inspiration from events in her own life to become one of Britain's best-loved children's authors.
Kerr was born in Berlin on June 14, 1923, fleeing Germany 10 years later after a policeman tipped off her father Alfred Kerr, a prominent Jewish writer, that the family was in danger from the rising Nazi power.
"My father was ill in bed with flu and this man rang up and said: 'They are trying to take away your passport, you must get out immediately'," she recalled in an interview with AFP in June 2018.
He took the first train to Switzerland and his wife and two children soon joined him. A day after their escape, the Nazis took power.
The family moved on to Paris before settling in London in 1936.
This story is loosely recounted from a child's perspective in Kerr's semi-autobiographical novel "When Hitler Stole Pink Rabbit" (1971) in which the fleeing girl can only take one toy and so leaves behind a favourite rabbit.
Kerr, who started drawing at a young age, credited the success of the book with being "published at a time when the Germans hadn't really managed to talk to their children about the past".
But she is better known for "The Tiger Who Came to Tea", released in 1968 to become a global classic of children's literature, with at least five million copies sold and published in more than 30 languages.
Kerr's first picture book, it tells of a girl and her mother interrupted at teatime by a huge, fluffy tiger who eats everything in sight before leaving again.
She was able to write up the story -- a bedtime favourite of her young daughter -- while her husband was at work and their two children at school.
The fictional family mirrors her own at the time, the illustrations featuring the yellow and white kitchen cupboards of their London home.
Kerr used tigers at a London zoo as models for her feline creation.
Next was "Mog the Forgetful Cat" (1970), the first in what became a 17-book series about the antics of a mischievous, egg-loving moggy inspired by her own pet.
"Goodbye Mog" (2002) was meant to be the last offering -- broaching the subject of death with the much-loved cat departing for heaven. But supermarket chain Sainsbury's persuaded Kerr to produce one more in 2015: "Mog's Christmas Calamity".
Proceeds of the last book were for Save the Children's work on child literacy, and a TV advert was the first to feature Mog in animation with Kerr herself also making a cameo appearance.
In her illustrated story "My Henry" (2011) -- for children and adults -- an elderly lady fantasises about adventures with her late husband, such as climbing Mount Everest, hunting lions, and riding dinosaurs.
Kerr dedicated the book to her husband Thomas Nigel Kneale, a respected screenwriter who died in 2006. The couple met at the BBC, where they both worked, and married in 1954.
Commenting on the book in 2011, The Telegraph wrote: "For all the depth of underlying emotion, there's a celebratory feel to it, an unfeigned lightness of spirit that, throughout her life, has been a great boon.
"It has helped her cope with widowhood just as it allowed her to get over the loss, exile, penury and frustration of her early life."
In 2012 Kerr was awarded an OBE (Order of the British Empire) for services to children's literature and Holocaust education.
