PLANET EARTH:OUR LOVING HOME
Animal Agriculture’s Generation of Deadly Black Carbon
|
|
|
|
|
Greetings,
eco-loving viewers,
and welcome to
Planet Earth:
Our Loving Home.
On today’s program
we examine the effects
of the short-lived climate
forcer, Black Carbon,
on ice masses
and planetary warming,
and the role
that animal agriculture
and deforestation
for livestock raising
play in intensifying
Black Carbon’s impact.
Black Carbon,
also known as soot, is a
powerful warming agent
that originates from
the incomplete combustion
of fossil fuels,
diesel exhaust, inefficient
cook stoves mainly used
in developing countries
burning biomass such as
dried dung, wood, brush,
or crop residue as fuel,
and the clearing forests
and savannas with fire.
When the Black Carbon
particles are airborne,
they have an intense
warming effect, but have
an even greater impact
when they are deposited
on ice masses.
This is a major concern
and why Black Carbon
emissions need to be
addressed immediately.
Its atmospheric lifespan
ranges from
one to four weeks
and its Global Warming
Potential (GWP)
over a 20-year timeframe,
has been calculated to be
between a staggering
1,600 to 4,700 times
the warming-power
of carbon dioxide.
Black Carbon’s
warming effect occurs
in two ways:
(1) In the atmosphere
as black particles
absorb sunlight
and generate heat; and,
(2) Particles are deposited
on the Earth’s surface,
in particular on ice masses
where they reduce
the ability of the ice
to reflect sunlight
back into space
and cause rapid melting
by generating heat
from absorbing sunlight.
Professor Jefferson Simões
is the director of the
Brazilian National Institute
for Cryospheric Sciences
and a National Delegate
to the Scientific Committee
on Antarctic Research
(SCAR).
He created the first
national laboratory
in Brazil dedicated to
glaciology and
geographical polar research,
and recently gave an
informative presentation
on the presence
of Black Carbon
in Antarctica and
its effect on ice masses
at the November 3, 2010
Leaders Preserving
Our Future:
Pace and Priorities
on Climate Change
conference in London, UK.
We know that they
(Black Carbon particles) are
spread from Arctic
to Antarctica,
elsewhere in the world.
They are very tiny particles
between 0.01 to 1 microns
in the atmosphere.
It stays in the atmosphere
just a couple of weeks
but is available to disperse
at longer ranges.
BC, or black carbon,
belongs to
short-lived pollutants.
And then comes
the most important point:
it’s the second most
important contributor
to global warming.
In fact, the potential
of black carbon
is estimated
to have a 55% of the
radiative forcing effect
of carbon dioxide.
So, the thing that we have
in this picture here
is the main places
that we have biomass
burning at the moment
in the year 2009.
As you can see,
mainly in the subtropical
and tropics, not only
in South America, but also
in Africa and Australia
and some countries like
Indonesia, Malaysia, and
others in Southeast Asia.
And, so, we can place
the following question,
how can this kind of
material be transported
to Antarctica?
It seems a long way.
For the last 10 years,
we have changed our idea
about the transport
of air masses
from South America,
or from the tropics
of South America,
to Antarctica.
By now we know
that cyclonic activity is
able to transport materials
in a short time,
in a week or so,
from the main areas of
biomass burning,
to the south and then
mainly to the northernmost
part of Antarctica,
that is
the Antarctica Peninsula.
Professor Simões
has been on several
research expeditions
to the Antarctic Peninsula
and has seen significant,
worrisome changes.
Over the last 20 years
in Antarctica
we have observed
several modifications
in the northernmost part
of that continent,
that’s known as
the Antarctica Peninsula.
We observed
in the last 20 years
the melt of the glaciers,
the collapse
of the ice shelves,
and that more than
20,000 square kilometers
of ice shelves of
the Antarctic Peninsula
have disappeared.
(There have been)
migrations of different
species further south
like some penguins.
Grass is appearing
on some islands
that didn’t have it before.
In short, we are observing
the further shifting south
of the isotherms,
of the lines
of the same temperature.
Antarctica contains
90% of the world's
water glaciers.
The rapid melting of
these ice masses means
serious consequences
for those
living in coastal areas
and on low-lying islands,
and also for food security.
The World Bank estimates
that just a one meter rise
in sea level
will inundate Asia's
rice-growing river deltas.
Many islands
would disappear, such as
Kiribati, the Maldives,
and Tuvalu because
their highest points
are only two meters
above sea level.
We’re approaching
a number of tipping points
very quickly that could
involve the melting
of the ice sheets
and all London New York
even Washington DC
could be inundated
and so forth
that goes on irreversibly
and of course
all sorts of feedback
effects particularly
within the Arctic,
the thawing of the tundra
that essentially feeds
on itself, a kind of
metastatic climate change.
And many of these things
are likely to happen
in the lifetime
of many of us right here.
Notable initiatives
that have been proposed
for mitigating Black Carbon
include replacing
polluting cook stoves
with cleaner,
more efficient ones,
and installing filters
on the exhausts
of diesel vehicles.
These will play
an important role
in improving air quality,
addressing health concerns
and abating a portion
of the warming.
However,
massive reductions
in Black Carbon
can be made by
addressing open burning
of agricultural lands,
in particular fires lit
to clear forests and
control vegetation regrowth
for livestock grazing.
It’s clear that, nowadays
the greatest part
of the deforestation,
biomass burning
in South America, comes
from the expansion
of the cash crops
and cattle farming.
The thing
that we are seeing is
that the farming frontier
is moving further North
over the Brazilian Savannah
that’s known as Cerrado,
towards the Amazon forest.
Halting the warming
of the ice masses
is an absolute necessity
in the challenge
to stabilize the climate
of our planetary home.
What is agriculture’s,
in particular
livestock farming’s, role
in all this?
About half or 47 to 61%
to be exact
of the Black Carbon
in Antarctica is
attributable to livestock
pasture management.
Until recently Mr. Gerard
Wedderburn-Bisshop
worked as
a principal scientist
with a remote sensing
science team responsible
for mapping tree clearing
via satellite imagery
in Queensland, Australia.
Now
Mr. Wedderburn-Bisshop
is Senior Scientist for
the World Preservation
Foundation and recently
gave a presentation
at a December 8, 2010
conference entitled
Black Carbon
and Short-Lived GHG
(Greenhouse Gas)
Mitigation
held in Cancún, Mexico.
Seventy percent of
global agricultural land
is used for livestock.
Much of the trees cleared
and feed crops undergo
repeated burning.
So it’s a source
of many things.
It’s a source of methane.
It’s a source of
soil carbon loss.
And of course, fire.
This is a map here of
the world’s deforestation.
You know what’s happening
in South America.
You know
Sub-Saharan Africa.
You know that
Indonesia and Malaysia
and Papua New Guinea
are being deforested
at a large rate.
This is, two 10-day periods
taken from
the last few months.
You can see
that the world is burning,
South America, Africa,
in different places,
different times,
Southeast Asia, Australia
is burning, and
some up in Russia there.
Okay, the pattern of fire
matches the pattern of
deforestation,
no surprises.
Fire retards the growth
and maintains the pasture.
Mr. Wedderburn-Bisshop
and his team of researchers
made an astounding
discovery about
animal agriculture’s
connection to the melting
of West Antarctica.
West Antarctica is
the fastest warming place
on Earth.
The melting there
is happening
at an alarming rate and
they’re discovering much
to the surprise
of researchers
that the Black Carbon
is also there
in large quantities.
Most from South America,
some from Africa and
some also from India.
The Black Carbon
is most concentrated in
the Antarctic Peninsula
and Western Antarctica,
both of which are warming
at rates far exceeding
the global average.
If we attribute
the Black Carbon
in the same proportion
as the deforestation,
remember that 80%
of Amazon deforestation
is for grazing
and livestock feed,
and in Africa
70% of the burning
of the open fires
are for livestock farming,
for pasture maintenance.
We see that when we add
the South American
and African proportions,
about half or 47 to 61%
to be exact
of the Black Carbon
in Antarctica
is attributable to livestock
pasture management.
This suggests
that grazing practices
are the most significant
Black Carbon contributors
to Antarctic melting.
The shorter-lived agents
are the ones
that we must address
if we’re going to reduce
the warming of this planet
in the short term,
which is all we’ve got.
The impact
of livestock production
is enormous.
First of all we have
the direct emissions
of methane from
the enteric fermentation,
the largest part of
all methane production
on the planet.
Secondly
we have deforestation,
which takes away
the CO2 directly,
and the burning
to maintain that pasture,
it also produces
Black Carbon and CO2
directly.
Now after you take away
the forest the soil carbon
also depletes, long term.
So the other effect
is that livestock produce
quite a bit of
tropospheric ozone, and
that’s produced mainly
by methane production.
So if we reduce
the methane production
we can control the ozone,
the tropospheric ozone
production, which is
a major warmer.
This is producing
20% of the warming
of carbon dioxide.
So if you add all those
together the impact
of livestock production
is enormous.
Deeply concerned about
the state of our planet,
Supreme Master Ching Hai
on many occasions
has highlighted
the urgent need to limit
Black Carbon emissions
and that ending
livestock raising
is the most effective
solution to dramatically
lessen levels of soot and
reverse climate change.
NASA scientists
are paying
increasing attention
to another very serious
source of global warming
- that is, black carbon.
It is 4,000-plus times more
heat-trapping than CO2.
The majority of
the black carbon particles
in Antarctica
are coming from where?
South American
rainforests that are burned
for the livestock industry.
Now we’re going
somewhere!
We must urgently
address methane
and black carbon,
both outcomes of
the meat industry,
immediately
we have to tackle it.
I pray all wise leaders
will halt
the lethal meat practice,
which is the main force
driving us to the point
of no return right now.
Our heartfelt thanks,
Professor
Jefferson Simões,
John Topping, Gerard
Wedderburn-Bisshop,
and Supreme Master
Ching Hai
for alerting the public to
the tremendous dangers
posed by Black Carbon
and your steadfast advocacy
for significantly
reducing soot emissions
right away.
It is clearly evident
that animal agriculture
is an enormously
detrimental practice
for countless reasons
and must be halted now
so that we can heal
and restore planet Earth
to her natural order.
May humankind quickly
awaken and adopt
the nature-supporting
and life-affirming
organic vegan diet.
