Around
250 million years ago,
a series of global warming
events resulted in 70%
of life on land and 95%
of marine life
being extinguished. University of Calgary
scientists in Canada are
the first to have found
evidence in the Arctic
that a huge volcanic
event led to the burning
of vast amounts of coal.
At that time,
the Earth's land was
contained on one large
continent called Pangaea,
where volcanoes
covering an area the size
of Europe began to erupt
through underground
coal beds, igniting
the carbon-dense material
and causing it to produce
immense ash clouds.
This in turn released
sufficient amounts
of greenhouse gases
to initiate runaway
global warming.
Speaking about
the findings
from their expedition,
researcher Dr. Benoit
Beauchamp stated,
“We saw layers with
abundant organic matter,
and … immediately
determined that they
were layers of coal-ash,
exactly like that produced
by modern coal burning
power plants.”
In addition, earlier research
has shown evidence
of hydrogen
sulfide poisoning.
Scientists believe that
during the Paleozoic era,
the planet was already
warming due to elevated
carbon dioxide levels
in the atmosphere.
The enormous amounts
of ash released
by the coal-burning
volcanic eruptions caused
an even further reduction
in oxygen supplies
to both land and water.
This in turn caused
a proliferation of
the bacteria that produce
poisonous hydrogen sulfide,
setting off changes that
resulted in what is now
regarded as the worst
extinction event
in the Earth's history.
We appreciate these
fascinating findings,
Dr. Beauchamp
and colleagues, and the
insights they provide into
our planet's ancient past.
May such cases aid
as warnings regarding
our own climate change
predicament today, so
that through wise actions,
devastating planetary
impacts can be averted.
During a September 2009
videoconference in Peru,
Supreme Master Ching Hai
spoke of the often
unforeseen dangers
accompanying
climate change, along
with the ways we could
avoid them entirely.
Supreme Master Ching Hai: We are not ready
for the changes
that are coming.
We are not ready at all.
We are not prepared enough.
Some of the changes
are even anticipated
to be unexpected,
because there are
many complicated
interacting factors.
The wisest action would be
to fix the situation
we have now and
prevent further damage,
then we won't even have
to worry about the future.
The smartest way would be
to stop the worsening
of global warming
by being vegan.
It sounds very simple
but it is the best solution,
the most effective
and the effect of it will be
felt almost immediately.
So please,
before the situation gets
any more out of hand -
let's choose the vegan diet.
