O Tempo Geológico e o Antropoceno | Gerson Fauth | TEDxUnisinos


how many years have you had tense rock

What is the story that this rock has?

Did you know that rock has history?

everything has a beginning everything has a medium and

not an end

This rock, I came here today too.

tell you about the time

it is not the time of the nervous ticking of

every day that you wake up from

Very early morning and sleep a lot

I did not come here late to speak either.

on the average age of a person of

70 80 years he is born grows and

silly case and 9

I came here to talk about the weather.

we have several technologies that

make us have and

conditions to study these rocks

through the mineralogical content that

exists within this rock is possible

tell the story of her telling

history tells the story

of the country a continent and even

install off the planet

also here within this and other

rocks could be the fossils

the fossils tells a story as a

world of you know the rocks have

ages reflects the coming age of the

land is 4.6 billion years old.

and it shows this simple rock that

came the great northern river 70 km from the

natal city has 3 billion and 400

millions of years can count a

story for us but if we do

an analogy and made a comparison

it is with time the geological time

related to one to one clock 4.6

billions of years in 24 hours is what

people can say that until 9 pm

of these 46

11 years ago the land had practically

a unicellular life of forms

microscopic at what moment things

began to change 80% of that interval

who goes until 9 pm has these

small animals

everything started to change two hours

on that same day how was this land

in this time

There is a lot of rain

all the things that are clashing

against land because we do not have the

atmosphere and the land is constantly

the high temperature

we live is very thin

then around 11 o’clock in the morning.

morning free oxygen arises

until then the best ones collided with

land and we did not have any

no atmosphere at all

state that protects us from

continuous or better the earth continues

there is a time to 600 million years

and is the first time you start

and it is this biota called the face biota

nobody knows if it’s animal if the plant

in knows nothing is registered in the rocks

600 million years or so

9 hours

life continues the earth advances and there

comes at 9 o’clock and 10 minutes

to 541 million years, there is a way

different forms that for the first time

has exoskeleton everything that is

represented here by the great preacher

There’s nothing like it today.

anomalocaris this guy was a great

predator at 9 10

and the history of the earth advances is

exactly at that moment to 541 million

the researchers did the same

geological time on the table because they

began to observe on the rocks of

all ages from 541 million

years of fossils that can be

to record what life on earth was like

was with the age of rocks and etc.

for this they created this table that

advances up to 4.6 billion years more

starts at 541 and goes to the top of this

table is zero

all the horizontal lines that you

are watching are lines that have

stress on the earth a stress that

there was a series of

animals and plants

but scientists say there are

five that are the most important and

more catastrophic ones that are there

positioned in these five the land passed

for a triz the life of the earth passed through

13

the first of them would have happened almost

at 11 o’clock it is 23 o’clock at night

of that day to 251 million years

behind

that was the limit was the triassic between

permian and triassic

see the land there is a

great continent

the ‘superman’ jea on them the animals

could switch from one side to the other.

other

at that time the land at or for a

strangulation of life practically

where 90 95% of all life that existed

on the planet was extinguished by drastic

environmental changes

the time continues to advance and then we

we reached 201 million years

this is the end of the triassic

dinosaurs that emerged early in the

Triassic here in Rio Grande do Sul and

in northern argentina

were small started to create body

they were a little bigger than a chicken

to 201 million years the supercontinent

pangea begins to differentiate begins

to fragment and start to have events

gigantic volcanic rocks changed the

temperature of the earth and extinguished good

part 80% of life on earth advances

we reached 66 million years ago

dinosaurs were never giants in the

history of the land there was

animal with so much weight

he advances and in that same moment to 66

millions of years again the earth passes

by a strangulation of life provoked

mainly due to two causes

the volcanism in India that is

shocking how many himalayas and the clash of

a big meteor that happened in new

canaan what would it be in mexico that would

cancun near cancun to 66

millions of years

the mall of a meteor was so

gigantic that would be 3 degrees on the scale

richter what is impossible for us

very big giant

the maximum we have of an earthquake is

9.5 very well for you have the idea

shock of this meteor could be so

has been so great that for three

years the earth was night if it was night

there is more photosynthesis of plants the

referees do not feed and then

oscar books do not eat in the living or

whether the entire food chain has been

and is there are rest because the

species always survive and in

when the dinosaurs were

extinct mammals arise

mammals already existed on earth but

they have adapted to this moment because

the great predators no longer existed

more dinosaurs that already

his great asset was in extinction

was 66 million years ago

mammals have proliferated but I have

another rock this rock came to aa 3

one thousand kilometers away from the coast

of rio de janeiro 3 thousand in one

depth of water depth of 3 mil

meters and more than 2,000 meters

drilling scientists look at these

rocks and can observe microfossils

these microfossils that you are

seeing this guy exactly this one

face has overcome the barrier that stress

environment and its wall is a great

recorder that can record the entire

water chemistry at that time to 66

millions of years

temperature conditions

of water to 66 million years

and how were the currents eee can

reconstitute the oceans

but the question is do we know where

is homo sapiens in this play

see you soon I told you that

this extinction of the dinosaurs was 66

millions of years that would be around

23 hours and 30 minutes

we do not know yet he did not appear

will come to 300 thousand years

and here it is represented by a man

well known to you and he appears

a girl only appears within that

our clock at 11:59 PM and

54 seconds

see six seconds we’re just

arriving

there is great discussion now

among scientists in the last five

ten years on the generation of a

new era that is called

anthropocene we will probably be

passing through the sixth extinction

We do not realize how I said the

rocks are millions of years being

human lives 70

but what would be the causes of these

changes

one of them would be related to

population

the world population is increasing

considerably in the time of Jesus

Christ

the population was 200-300 million

of people

would be the population of Brazil living

across the globe

in 1804 1 billion people

two billion people 3 billion

people 4 5 6 7 and today we are 7 billion

576 thousand people living and

proliferating nor good rabbit but came the

man took 300,000 years to reach the

billion people and now the

every ten years

he jumps 1 billion he goes the population

world reaches 1 100 days say that it will

reach a certain level where it will

stabilize in 10 billion people

but the great debate is at what

anthropocene you or what is the mark

let the rocks that I just

show you which is the the marker

the great marker is the detonation

nuclear

the exercises performed in the

40’s and 50’s

marking on the rock will leave

eternally a radiation that can be

detected by equipment and technologies

The big question is how will we stop?

This is the question I ask is because

we can not stabilize if

we are so smart and we are

here is so little time and we can do

a change in relation to this

thank you
