hello my name is leandro and I come to
tell them something that really seems to me
interesting to share with all of you
this glass that he just filled has
3,800 million years
you may think I’m crazy
but if you give me just a few minutes
they’re going to realize that I’m not lying
I tell them that she makes a few
years I have been devoting my theme
Water
the origin and the forms under which
it is presented to us it is likely that in a
situation similar to this island from
boy I was attracted to this vital
element
although to be honest, it’s much more
probable and knowing how I am that
has been something more like this
[Music]
then as I left feeling
a little bigger
my parents dedicated to science
I was always attracted to the idea
to look a little beyond worrying
more through the forest by the tree that
cover a curiosity that we tend to go
losing in this way feeding him
a curiosity that we lose to the extent
that we are becoming adults in part
because we must just become
in adults living without meaning
besides a clock and doing things
that the rest of the mortals do
so I think a little bit of having
been for this series of reasons that
I decided on this profession
the geologists we could do something like that
like forensics on planet earth
we are interested in knowing how and when
happened and pointed out that it always intrigues us
it is time that magnitude that we
we create to be able to give
importance to things and sort them in
our head we need it for some
reason that I do not know already a reason that
I do not end up understanding the human being
he thinks he deserves all the resources
that are within your reach
something like if it were a
infinite eternal divine gift he
a whole tree of which he is worthy
beyond the circumstances something
that was already assigned and written that we
he touched us
founded obviously on the false idea of
that our passage through the earth is
transcendental and important and what happens in
those cases in which the resource
the resource is at your reach signature
treaties international conventions on
a region with apparently
peaceful for then yes obviously
negotiate its use in other cases to be
human likes to wear a little more
practical invent an excuse to create a
war and after that yes decide
who and how will you manage it but
what I want to tell you today is all the
story that exists behind these
five seconds of satiety purity and
vitality that we live at the beginning of
this talk and that we do all the
days in our house
most of the processes that give
origin to the water that we consume all
days from rivers and aquifers
springs carry implicit numerous
known changes as we must learn
of the secondary as a hydrological cycle
keep in mind that most of
the processes that involve water
they involve transformations constantly
from one state to another and that happens in
the earth
according to various theories some ago
3,800 million years
in this way the water changes
constantly from one state to another
then what I want today
show them where these are coming from
five seconds and the 3.8 billion
years
For that I propose an example which
it is a simple analogy what
Come is one of the best-selling books
from around the world the bible but
stay calm here we are not going to
speak neither of its content nor the parties
in which it is divided neither to the
religion to which the
exercise that I propose is that
let’s try to size the history of
the earth is the 3,800
millions of years
in this simple book so if I
accompany us we begin
if it were like that the oceans
been the first to be formed
they would represent the entire book already
that you have to see the whole story and
they have witnessed all forms
why the earth was changing
if we look for something more recent the
Guaraní aquifer with 245 million
years was formed when South America
I was still connected to Africa in a
totally different form than the one
we know and from our book
would represent about 123 pages think
this is a chapter not bad
the mountain range of the Andes 150 million
of years believe me that 150 million ago
of years the mountain range did not have the
way you have today
after all this time thanks to the
launching of those great monte
may rocky snow
accumulated in the great summits
form the glaciers and from that
to be able to take it once they are the
series melt populations in
the plain and of our book would be
about 75 pages of large aquifer
artesian in australia that maybe less
known is still one of the aquifers
most extensive in the world
they are about 250 million years old
equivalent to 126 pages
there we have another chapter the ice
Antarctic 37 million years
we assume about 15 pages or a little
we could say a little more and the
Lake Baikal that maybe not much
you know that is the most extensive lake in
world’s largest world 23 23 thousand
600 cubic kilometers of water that
they say that now the exercise that
I propose is that you try to get involved
in this story try to size
how much we represent of this book what
he left well sitting in his head they want
tell them
we are two prayers at the end of this
long story but that is what we
makes believe is not so important until
that looks like a symbology now for a
moment and now I ask them to try
try to size all the machinery
that the universe puts to work for
create side form glaciers courses
water and only there we can see our
insignificance and how lucky they are
we are counting on the work of
missions and same
from years without pause in a world that
measured by the monetary value of things
I am convinced that it would not reach us
nor selling all the gold reserves
of the world and the planet to raise the
less a mountain and this is what I think
which is wonderful for a second
think the millions and millions of
cubic meters moving from one side
for the other evaporating masses of water
transporting tracking so that it is
conformed the large aquifers to
amazon river in brazil the nilo river in
the East African that allows vast
populations live on the riverbank this river
if we are more curious we can still see
which is actually almost less likely
that those sands exist or even
even exist
remember that most of the
Geological processes depend on one or
two factors with slight and even almost
imperceptible variations but that
prolongs over time generate
big changes
so my call today is to the
reflection so that we do not create ourselves so
important in this story
after all, as we saw recently
we are two sentences at the end of the book
this is a long time ago and it cost
much much much put it in conditions
for us we are really
fortunate the truth of being able to tell
with the fruit of the work of millions of
years and finally maybe when the
human being understand what is his role in
this great story may already be late
to realize that behind a
simple glass of water like this
there is a great sage who comes to
tell us in just five seconds
a story that started 3,800
millions of years
thank you very much
[Applause]
