team of US researchers have newly theorized that when 80% of the
population of large-bodied mammals in the Americas was hunted to
extinction following the arrival of humans some 13,000 years ago, the
resulting sudden decrease in methane emitted naturally by the animals
may have been the primary catalyst for the dramatic Younger Dryas event,
a sudden planetary cooling that lasted for at least 1,000 years.
now, the onset of the Younger Dryas “cold snap” was known to be sudden,
but its cause has long been a mystery. Supreme Master Television spoke
with one of the study’s authors, Dr. S. Kathleen Lyons, a paleobiologist
at the Smithsonian Institution in the USA. Dr. S. Kathleen Lyons – Resident Research Associate, Paleobiology, Smithsonian Institution (F):
13,500 years ago was when humans arrived in North America, and within
2,500-3,000 years, by 10,000 years ago, the last of these large mammals
had gone extinct.
My co-authors and I all believe that human
hunting was primarily responsible, because if you look at the pattern
and the timing of the extinctions across the globe, what you find is
that on every continent where there was an extinction of these large
mammals, it’s coincident with the arrival of humans, but not necessarily
coincident with climate change.
VOICE: Dr. Lyons and her
colleagues’ findings suggests that the decrease in atmospheric methane
as the populations of giant hunted mammals declined was significant
enough at that time to disrupt the planet’s temperature and cause a
relatively short ice age. Dr. Kathleen Lyons (F):
The extinct mammals could have been producing anywhere between 9 and 25
teragrams of methane each year. Corresponding to the time that mammals
went extinct, we do record, from ice cores, a drop in methane that’s
then coincident with the Younger Dryas cold snap.
And what we found
was that the rate of the change in methane at the Younger Dryas is
significantly higher than at any other time over the last 500,000 years.
VOICE: Our appreciation Dr. Lyons and colleagues for your
research showing how such drastic human actions could have far-reaching
tragic consequences. At this fragile time on our planet, when raising
livestock for killing is creating a similar ecological imbalance, may we
turn to virtuous lifestyles in harmony with other species to preserve
all lives on Earth.
In various discussions, Supreme Master
Ching Hai has connected past human behavior with current times to urge
for fast and proper environmental action.
Supreme Master Ching Hai:
We see the pattern is that no society can last long if they refuse to
sustain the lives of their own members and fellow beings; I mean,
including all the beings, like animals and trees. http://www.nature.com/ngeo/journal/v3/n6/full/ngeo877.html
Or, if they
destroy the environment they live in, then that society cannot live
long. The real problem is our meat consumption, the tendency of mass
killing that we have made a part of our lives.It is not normal.
cannot earn a living or sustain a living by death. So, if we don’t
eliminate meat consumption, we could never reach even a low, low impact
on the environment, no matter what else we do.
We must stop the
most inefficient, unsustainable, life-destroying practice of murdering
animals and stop it now. Stop it yesterday. The animal-meat industry has
to go - be it animals from the air, the land or the sea.
