Paris (AFP) - Diplomats from 130 nations gathered in Paris on Monday to validate a grim UN assessment of the state of Nature and lay the groundwork for a rescue plan for life on Earth.
The
destruction of Nature threatens humanity "at least as much as
human-induced climate change," UN biodiversity chief Robert Watson said as
the five-day meeting began.
"We
have a closing window of opportunity to act and narrowing options."
A 44-page
draft "Summary for Policy Makers" obtained by AFP catalogues the 1001
ways in which our species has plundered the planet and damaged its capacity to
renew the resources upon which we depend, starting with breathable air,
drinkable water and productive soil.
The impact
of humanity's expanding footprint and appetites has been devastating.

million species face extinction, many within decades, according to the report,
and three-quarters of Earth's land surface has been "severely
altered".

A third of
ocean fish stocks are in decline, and the rest, barring a few, are harvested at
the very edge of sustainability.
A dramatic
die-off of pollinating insects, especially bees, threatens essential crops
valued at half-a-trillion dollars annually.
Twenty
10-year targets adopted in 2010 under the United Nations' biodiversity treaty
-- to expand protected areas, slow species and forest loss, and reduce
pollution -- will, with one or two exceptions, fail badly.
Based on an
underlying report that draws from 400 experts and weighs in at 1,800 pages, the
executive summary has to be vetted line-by-line by diplomats, with scientists
at their elbow.
The
Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem
Services (IPBES) document, once approved, will be released on May 6.
Historically,
conservation biology has focused on the plight of pandas, polar bears and a
multitude of less "charismatic" animals and plants that humanity is
harvesting, eating, crowding or poisoning into oblivion.
But in the
last two decades, that focus has shifted back to us.
"Up to
now, we have talked about the importance of biodiversity mostly from an
environmental perspective," Watson told AFP ahead of the Paris meet.

Agriculture is key
"Now
we are saying that Nature is crucial for food production, for pure water, for
medicines and even social cohesion."
And to
fight climate change.
Forests and
oceans, for example, soak up half of the planet-warming greenhouse gases we
spew into the atmosphere.
If they
didn't, Earth might already be locked into an unliveable future of runaway
global warming.
And yet, an
area of tropical forest five times the size of England has been destroyed since
2014, mainly to service the global demand for beef, biofuels, soy beans and
palm oil.
"The
recent IPCC report shows to what extent climate change threatens
biodiversity," said Laurence Tubiana, CEO of the European Climate
Foundation and a main architect of the Paris Agreement, referring to the UN's
climate science panel.
"And
the upcoming IPBES report -- as important for humanity -- will show these two
problems have overlapping solutions."

Extinctions hard to see
That
overlap, she added, begins with agriculture, which accounts for at least a
quarter of greenhouse gas emissions.
Set up in
2012, the IPBES synthesises published science for policymakers in the same way
the Intergovernmental Panel for Climate Change (IPCC) does on climate.
Both
advisory bodies feed into UN treaties.
But the
1992 Convention on Biological Diversity (CBD) has always been a poor stepchild
compared to its climate counterpart, and the IPBES was added as an afterthought,
making its authority harder to establish.
Biodiversity
experts are trying to engineer a "Paris moment" for Nature akin to
the 2015 Paris climate treaty.
Public
concern about global warming has crystallised around impacts ranging from
rising seas to deadly heatwaves, and the Paris pact's hard target for capping
the rise in global temperatures.
The 2018
IPCC report cited by Tubiana added a time imperative: to hold the line at 1.5
degrees Celsius (2.7 Fahrenheit), the world must reduce CO2 emissions 45
percent by 2030, and become "carbon neutral" by mid-century, it
concluded.
But finding
the equivalent for Nature has proven difficult.
"Extinctions
are not something the public can easily see," said Watson.
A growing
number of scientists and NGOs are calling for 30 to 50 percent of Earth's
surface to be "sustainably managed" by 2030, and more thereafter.
But the
draft report makes no such concrete proposals.
The next
opportunity for a visionary plan to be ratified would be the next full meeting
in October 2020 of the parties to the Convention on Biodiversity in Kunming,
China.
