hello I bring you a little fish
this fish is a girel of us
reaches 2 Juli singers and this little
fish I wanted to bring because they
change sex and yes there are some
fish that change sex and then he
are specialists in the change of
sex of the fish I’m part of my
kids a field of study it was the
grouper because the rhythm the grouper they
change sex or if they change
first females sex badly then
like the girelle we could say we
could simply say that the
grouper becomes the grouper and that the
girelle becomes urgent irène and for
those of you who consume
bream and well aware that the sea bream
sky changes sex but in the other
sense they emanate first hurts and
so we could say that sea bream
becomes the doral then if I tell you
all this is just to express a
billionth of that biodiversity
we reserve as surprises as
solution as a source of wonder
and as hope
so when I decided to talk to you
of diversity tonight done today
more than I told myself I have a small
little thought it happens to me time in
time and I go girl how com
how to get this dabio idea
diversity and I propose a small
exercise of reflection on us as
one and then transposition afterwards
so I’m going to ask audrey to me
join on stage good I would like
gifts
audrey do you know what
species you belong to homo sapiens
bravo so audrey is again this
breaks like the little mermaid and 1
corrects high school mont miroux
epinephelus microdon is what for
as much as it tells us they have
would not really like so we’re going
try to know a little bit more and
if you look at audrey ben I see
first one that’s a new sapiens
a priori female brassus when
even finally finally number it’s not a
girel good that she is brunette she has
green eyes she has some
dress style good voila but that
does not say much more about audrey
so we’ll try to find out a little bit
more audrey is what you see what you
screw to carry-the-wheel
you work in what areas the
human resources and you work in
team
yes do you like to travel a love
abroad perfume or general and at
mali bravo do you cook
yes you eat organic or not bio
preference
you listen to classical music from
quite chaotic rap rock and then the
Sunday morning you make fat
morning
stop stop stop we’ll stop there
will not go into the intimate life
of audrey but what I wanted you
show by that is that what is
defined audrey are no longer these
relationships to the outside world like
is that after a species is so so
I had the fatal power so if
indeed we had to represent his
links to the outside world and well what
would be thousands of sons who will leave
of audrey as so many links sharing
vis-à-vis the ecosystem in which
she lives but it would also be
thousands of sons who would come to
audrey as so many sources for 6
reggae and feed on life and if
I had the fatal power actually
to make audrey disappear at once
magic wand
then at that moment these are
all of these links that would be
completely broken and who
would destabilize the ecosystem see the
would completely upset me
thank
so you live today the
sixth phase of extinction of species
on earth
unlike the previous five
she is considered to be a thousand
times superior to others and especially
it is entirely due to the activities
human or heard four is very
mainly due to the activities
so what does that mean
means that the bad news is
that we are responsible
and the good news is that we
are responsible and so that one
can act on it so we will not get
telling stories is not easy
but it’s not lost,
that’s what we will try to see
together through some examples
that I chose to show you that
no we’re going off first off the
canada on the big world newfoundland and
on this great newfoundland world during
years for all 20th century on
to fish the cod the cod to remember
for some of you cod the
cod is the same thing we talk about cod
wise board is salty or black
in upstream jean brandade and of
cod they have it’s true or where
frozen but it’s the same fish
fished at 800 thousand tons of
cod on the bench to nine it’s just
colossal to give you an idea what
that represents
if today we cumulate what the
French fishing produce in France
metropolitan in dom tom
aquaculture shellfish farming the
soft fishing we can not 708
prevent it 800 thousand tons on a site
and one species is colossal
and then in 70 what happened
there were first alerts the
catches began to fall and the
Canadian government began to
to take measures not enough and
so in 91 he decided to close
totally cod fishing is
therefore to establish what is called a
moratorium
twenty-five years after the cod is
still not handed out so why the
low floor because we sinned too much
that’s sure and certain but it’s
especially because we have completely
reversed the cycle of things
in fact the cod asa seen she had seen
come the blow and started to
to reproduce more and more young is
what a lot of fish do when
there is an operating pressure but
in doing so the phrase leeds is less
in two smaller sizes
agile and its texts it’s like that
a spiral of extinction snaps
and the cod is like the haddock was
rushed on this area will consume
a lot of small fish too there
was a lot of there is an ecosystem
extremely rich and well these little
cod today have become the
prey to small fish that eat
I used to be angry and it’s like
that we completely reversed the
course of things
so we hear here or there today
that yes the love had maybe is in
train back in ac small signs
that suggest that but nothing
nothing of course but what we have
forgot to say that at the time there is
thirty thousand jobs that have been
destroyed is that there are villages
whole were devastated
whole families ravaged by the
unemployment and that down to earth as
at sea life went away so I
sense that I have a little lead
the atmosphere there I’m going to spend on
positive things and we’ll go see
this time we’re going to the ocean
austral and we’re going to have an animal
fantastic
he’s called the emperor penguin on
the crozet archipelago and more
precisely on the island of
possession on the company’s feet
cross one of the biggest sleeves
third of the world
I’m shooting there, you’ll live
monchels finally where they come from
reproduce in this case and the penguin
Emperor is a fantastic animal
it’s a bird that does not fly in
the air but flies in the water to make
simple he will feed himself
very far from the island of
possession 300 km away it will be
feed on squid and fish
are 200 meters deep so
you imagine the journey to go
feed them to feed on a forehead
polar the polar front it’s
the confrontation of Antarctic waters and
sub- Antarctic waters
these are usually zones of
friction that are very very conducive to
life so to riches and so to the
food
the male and the female take turns to
hatching the egg
and when one convent the ofs the other
parent feeding at sea
two weeks before the outbreak of
little chick is the female who is
go and she’s going away she goes the
look for food the problem
is that the polar front it
move it’s times it’s not up to
300 km it is 600 km
because of another phenomenon that is
goes into the south pacific which
is called el niño so is the return
is uncertain and the date of return is
uncertain
and there we realized that the evil
was able this is the female was
not come back in time to regurgitate at
his young chick a food he
had ingested three weeks ago
he had kept in his stomach 38
degrees celsius in perfect condition
retention
it’s still a pretty discovery
amazing and so the researchers the
in fact these discoveries have
certainly go much further and have
discovered that the penguin produce a
molecule that is stressing is and who
was destroying the bacteria of the
digestion to be able to keep this
food at 38 degrees in his
stomach to feed his little one so at
beyond the extraordinary life of this
fantastic animal
we can see that nature invents
permanence of solutions for itself
and that these same solutions they
can be used by man
why because today these
discoveries and well they give rise
to measures that are being taken and
this molecule is today
used to fight against
nosocomial diseases and in particular
staphylococci
it will be used also probably
to be able to preserve food
in conditions where we have not
access to the cold so it’s exciting
and that’s where the convoy reserves it to
Possibility holdings that we offer
the possible biodiversity
to continue on we will go on the
mont saint michel
so we will get closer to our shores
and this mount saint michel which is
world famous he is surrounded by
salt marsh and salt marsh his meadows
salty are known for its agriculture
it’s up to us from your rooms and
these calves from your rooms and who are
very very good and but the swamps of
saleh was less known
it houses a time called the water
bubbling this tent is there she
seemed to be of little interest
ecological
and then we actually realized
that this plant when it takes shape
when she dies she produces 36 tons
per hectare per year of material
dry by comparison one hectare of
maize made 10 to 12 tonnes per hectare
and by year and in addition it is necessary to bring
200 kg of nitrogen fertilizer to get there
and this organic matter and well he
will be digested by little ones
crustaceans by bacteria
she’s going to go to Mount Bay
saint michel will fertilize zones
there will be some phytoplankton that has
pushed and we’re going like that
produce in this sold mount bay
Saint Michel 10 to 12 tons during
ten thousand tons of oysters and 6000
tons of mussels but that’s not all
because in fact we will continue to
break down its swamps which are very
regularly covered by the
tide and well will allow the little
bard and small mula who live in
these waters come to feed for
their first year and said to find 90%
their growth needs
it is to say if a plant which at the beginning
was not necessarily very
interesting and well present actually
a major ecological interest is
responsible for a whole cycle that is
extremely virtuous so what is it
our link to biodiversity our
link to biodiversity it’s simple
it’s dependent and solidary all
simply because we are we in
are part and
indissociable then if we want
continue to amaze us
the history of the mountain cho of the small
girel de montpeyroux and for those
of you who are proof authors
was going to dive on the reefs
coral so I believe I believe and I
am really intimately convinced like
he wrote felix antoine savard is a
Quebec priest writer
we have a lot better to do than
worry about the future we have
poorly prepared that’s what we do
every day with my beautiful team and
other teams around the world
but for that we need you because
that we are all concerned and this
will be like that we will be able to achieve
Thank you
