What choices does humanity have before Earth`s death? | Karwan Tahir | TEDxDuhok


if you look at earth from above you will

if you look at earth from above you will see how thin the atmosphere is and that

see how thin the atmosphere is and that

see how thin the atmosphere is and that the atmosphere cannot hold on forever

1/4 of Earth is land and the sea level

1/4 of Earth is land and the sea level is rising which means the amount of land

is rising which means the amount of land

is rising which means the amount of land that we have is decreasing and most of

that we have is decreasing and most of

that we have is decreasing and most of the lands are turning into deserts the

the lands are turning into deserts the

the lands are turning into deserts the weather is getting warmer and warmer and

weather is getting warmer and warmer and

weather is getting warmer and warmer and the atmosphere is getting dirtier due to

the atmosphere is getting dirtier due to

the atmosphere is getting dirtier due to greenhouse greenhouse gases and with all

greenhouse greenhouse gases and with all

greenhouse greenhouse gases and with all of this the human population is

of this the human population is

of this the human population is increasing so if it is going to continue

increasing so if it is going to continue

increasing so if it is going to continue like this the earth can now told us

like this the earth can now told us

like this the earth can now told us anymore so what should we do we have to

anymore so what should we do we have to

anymore so what should we do we have to change our way of living we have to find

change our way of living we have to find

change our way of living we have to find a solution for this according to what

a solution for this according to what

a solution for this according to what Stephen Hawking said that humanity has

Stephen Hawking said that humanity has

Stephen Hawking said that humanity has less than 200 years to find a new place

less than 200 years to find a new place

less than 200 years to find a new place to live on and he is right and according

to live on and he is right and according

to live on and he is right and according to our abilities and methods that we can

to our abilities and methods that we can

to our abilities and methods that we can improve them and develop them to be used

improve them and develop them to be used

improve them and develop them to be used in the near future there are actually

in the near future there are actually

in the near future there are actually two places

two places

two places scientists believe humans can use them

scientists believe humans can use them

scientists believe humans can use them for living and they are completely

for living and they are completely

for living and they are completely different the first place is the oceans

different the first place is the oceans

different the first place is the oceans we live only in one quarter of Earth so

we live only in one quarter of Earth so

we live only in one quarter of Earth so now it is time to use the other 3/4 of

now it is time to use the other 3/4 of

now it is time to use the other 3/4 of Earth which is the oceans ok how can we

Earth which is the oceans ok how can we

Earth which is the oceans ok how can we live on the oceans or in any other water

live on the oceans or in any other water

live on the oceans or in any other water world we can actually if we try like

world we can actually if we try like

world we can actually if we try like there are some people who have already

there are some people who have already

there are some people who have already adapted to life on the oceans so long

adapted to life on the oceans so long

adapted to life on the oceans so long ago and towards some examples of them

ago and towards some examples of them

ago and towards some examples of them here is the Bajau laut bill

here is the Bajau laut bill

here is the Bajau laut bill their village in the middle of the sea

their village in the middle of the sea

their village in the middle of the sea and they live almost their entire life

and they live almost their entire life

and they live almost their entire life there so as you can see with only some

there so as you can see with only some

there so as you can see with only some pieces of food they have built their

pieces of food they have built their

pieces of food they have built their abodes there and most of the families

abodes there and most of the families

abodes there and most of the families here has no money

here has no money

here has no money they say the oceans provide us

they say the oceans provide us

they say the oceans provide us everything we need and to give another

everything we need and to give another

everything we need and to give another example of cat ba island from Vietnam

example of cat ba island from Vietnam

example of cat ba island from Vietnam those people are more modern people they

those people are more modern people they

those people are more modern people they have even schools and a hospital here

have even schools and a hospital here

have even schools and a hospital here and most of the people who have never

and most of the people who have never

and most of the people who have never stepped on the land so if you look at

stepped on the land so if you look at

stepped on the land so if you look at them with their abilities and with only

them with their abilities and with only

them with their abilities and with only traditional methods without any

traditional methods without any

traditional methods without any technology they live there so what can

technology they live there so what can

technology they live there so what can we do with our high and modern

we do with our high and modern

we do with our high and modern technology let’s come to have a look of

technology let’s come to have a look of

technology let’s come to have a look of what we could do or what we have done we

what we could do or what we have done we

what we could do or what we have done we have built some oil production stations

have built some oil production stations

have built some oil production stations on oceans that thousands of people work

on oceans that thousands of people work

on oceans that thousands of people work there or live there and also we have

there or live there and also we have

there or live there and also we have built highway bridge on oceans and we

built highway bridge on oceans and we

built highway bridge on oceans and we use some ways of forming called

use some ways of forming called

use some ways of forming called aquaculture or aqua forming it is a way

aquaculture or aqua forming it is a way

aquaculture or aqua forming it is a way of forming and breeding seafood in a

of forming and breeding seafood in a

of forming and breeding seafood in a pencil pen system like this it contains

pencil pen system like this it contains

pencil pen system like this it contains fish plants anything that can grow in

fish plants anything that can grow in

fish plants anything that can grow in water and it also can provide a large

water and it also can provide a large

water and it also can provide a large quantity of seafood to the global and it

quantity of seafood to the global and it

quantity of seafood to the global and it makes less use of wild fish like more

makes less use of wild fish like more

makes less use of wild fish like more than a half of seafood in United State

than a half of seafood in United State

than a half of seafood in United State is formed with this way and the oceans

is formed with this way and the oceans

is formed with this way and the oceans are providing us a special type of

are providing us a special type of

are providing us a special type of renewable energy called ocean waves

renewable energy called ocean waves

renewable energy called ocean waves energy it is a way of converting ocean

energy it is a way of converting ocean

energy it is a way of converting ocean waves to electrical power with different

waves to electrical power with different

waves to electrical power with different methods and different stations and not

methods and different stations and not

methods and different stations and not only this we can even build solar and

only this we can even build solar and

only this we can even build solar and wind power stations on ocean so if we

wind power stations on ocean so if we

wind power stations on ocean so if we try to develop these methods of

try to develop these methods of

try to develop these methods of constructing and building I believe we

constructing and building I believe we

constructing and building I believe we can even go on to build cities on oceans

can even go on to build cities on oceans

can even go on to build cities on oceans that can be refused for many people now

that can be refused for many people now

that can be refused for many people now let’s come to talk about the second

let’s come to talk about the second

let’s come to talk about the second place which is the outer space planets

place which is the outer space planets

place which is the outer space planets and mostly its planet Mars the first

and mostly its planet Mars the first

and mostly its planet Mars the first thing we should know is how we can reach

thing we should know is how we can reach

thing we should know is how we can reach Mars the most practical way to do that

Mars the most practical way to do that

Mars the most practical way to do that is called cycling pathway to Mars which

is called cycling pathway to Mars which

is called cycling pathway to Mars which it has been suggested by dr. Buzz Aldrin

it has been suggested by dr. Buzz Aldrin

it has been suggested by dr. Buzz Aldrin he was the one who went to the moon with

he was the one who went to the moon with

he was the one who went to the moon with Neil Armstrong so now he has another

Neil Armstrong so now he has another

Neil Armstrong so now he has another dream of sending humans to Mars and here

dream of sending humans to Mars and here

dream of sending humans to Mars and here is how it works

Earth and Mars are orbiting the Sun just

Earth and Mars are orbiting the Sun just like this so as you can see there is a

like this so as you can see there is a

like this so as you can see there is a specific range that Earth and Mars are

specific range that Earth and Mars are

specific range that Earth and Mars are in the closest position to each other so

in the closest position to each other so

in the closest position to each other so only at this range we can go to Mars or

only at this range we can go to Mars or

only at this range we can go to Mars or return back from Mars so according to

return back from Mars so according to

return back from Mars so according to Alderon cyclic way we will send a

Alderon cyclic way we will send a

Alderon cyclic way we will send a spacecraft named cycler the black one

spacecraft named cycler the black one

spacecraft named cycler the black one that will travel between Earth and Mars

that will travel between Earth and Mars

that will travel between Earth and Mars perpetually forever using gravitational

perpetually forever using gravitational

perpetually forever using gravitational assist and it will take six months until

assist and it will take six months until

assist and it will take six months until we can reach Mars with this way and the

we can reach Mars with this way and the

we can reach Mars with this way and the time that it takes for Earth and Mars to

time that it takes for Earth and Mars to

time that it takes for Earth and Mars to return back to the same orientation from

return back to the same orientation from

return back to the same orientation from which they started is 18 months so as

which they started is 18 months so as

which they started is 18 months so as you go to Mars you have to stay there

you go to Mars you have to stay there

you go to Mars you have to stay there for 18 months until you can come back

for 18 months until you can come back

for 18 months until you can come back home again and also another six months

home again and also another six months

home again and also another six months for returning back that means 30 month

for returning back that means 30 month

for returning back that means 30 month journey far away from home in this way

journey far away from home in this way

journey far away from home in this way we can send both humans and cargoes to

we can send both humans and cargoes to

we can send both humans and cargoes to Mars so as we know in 2030s

Mars so as we know in 2030s

Mars so as we know in 2030s we will send the first humans crew to

we will send the first humans crew to

we will send the first humans crew to Mars with this way

Mars with this way

Mars with this way here is how we can reach more now what

here is how we can reach more now what

here is how we can reach more now what we will do one more when we land on Mars

we will do one more when we land on Mars

we will do one more when we land on Mars we will explore it and try to find any

we will explore it and try to find any

we will explore it and try to find any signs of life on it and also investigate

signs of life on it and also investigate

signs of life on it and also investigate the way we can establish a human

the way we can establish a human

the way we can establish a human settlement there because Mars has many

settlement there because Mars has many

settlement there because Mars has many resources to support life for humans

resources to support life for humans

resources to support life for humans like we can generate rocket fuel and

like we can generate rocket fuel and

like we can generate rocket fuel and supply breathable air from Martian

supply breathable air from Martian

supply breathable air from Martian atmosphere gases and also we can use

atmosphere gases and also we can use

atmosphere gases and also we can use mineral supplies of Mars for construct

mineral supplies of Mars for construct

mineral supplies of Mars for construct constructing purposes and eventually

constructing purposes and eventually

constructing purposes and eventually there will be a renewable energy to use

there will be a renewable energy to use

there will be a renewable energy to use like geothermal and solar and wind

like geothermal and solar and wind

like geothermal and solar and wind energy these resources would allow us to

energy these resources would allow us to

energy these resources would allow us to lower that lower the amount of materials

lower that lower the amount of materials

lower that lower the amount of materials and equipments that must be taken from

and equipments that must be taken from

and equipments that must be taken from earth which will make it cheaper and

earth which will make it cheaper and

earth which will make it cheaper and easier for us so when eighteen-month

easier for us so when eighteen-month

easier for us so when eighteen-month passed and the first crew start to

passed and the first crew start to

passed and the first crew start to return back another cruel arrive at the

return back another cruel arrive at the

return back another cruel arrive at the same time to continue Mars exploration

same time to continue Mars exploration

same time to continue Mars exploration and this will happen continuously until

and this will happen continuously until

and this will happen continuously until we can establish the first permanent

we can establish the first permanent

we can establish the first permanent human settlement on Mars now a free come

human settlement on Mars now a free come

human settlement on Mars now a free come to think about these two places like

to think about these two places like

to think about these two places like living on Mars or in oceans if you think

living on Mars or in oceans if you think

living on Mars or in oceans if you think about it they can only provide life to

about it they can only provide life to

about it they can only provide life to so few amount of people compared to our

so few amount of people compared to our

so few amount of people compared to our huge population and those people who

huge population and those people who

huge population and those people who will live there they will always need

will live there they will always need

will live there they will always need life support from Earth so without the

life support from Earth so without the

life support from Earth so without the earth life will be temporary there and

earth life will be temporary there and

earth life will be temporary there and we cannot just depend on artificial life

we cannot just depend on artificial life

we cannot just depend on artificial life support there for a long time because we

support there for a long time because we

support there for a long time because we always need life support from natural

always need life support from natural

always need life support from natural sources of Earth which are we are losing

sources of Earth which are we are losing

sources of Earth which are we are losing them any place any area any life form of

them any place any area any life form of

them any place any area any life form of Earth we are losing has effects on us to

Earth we are losing has effects on us to

Earth we are losing has effects on us to give an

give an

give an example one of the scenarios is losing

example one of the scenarios is losing

example one of the scenarios is losing the Arctic Isis we all recognize the

the Arctic Isis we all recognize the

the Arctic Isis we all recognize the Arctic’s as huge mountains of ice but

Arctic’s as huge mountains of ice but

Arctic’s as huge mountains of ice but their role in the movement of the oceans

their role in the movement of the oceans

their role in the movement of the oceans and also redistribute in global heat is

and also redistribute in global heat is

and also redistribute in global heat is important for life

important for life

important for life let me explain in the Arctic’s the water

let me explain in the Arctic’s the water

let me explain in the Arctic’s the water gets cooler as it gets cooler it’s

gets cooler as it gets cooler it’s

gets cooler as it gets cooler it’s heavier than before so it sinks below it

heavier than before so it sinks below it

heavier than before so it sinks below it is replaced by a new warm water which

is replaced by a new warm water which

is replaced by a new warm water which will cool down with the same process and

will cool down with the same process and

will cool down with the same process and it will push the water will with its way

it will push the water will with its way

it will push the water will with its way so this cyclic process it makes the

so this cyclic process it makes the

so this cyclic process it makes the ocean’s water to move around the world

ocean’s water to move around the world

ocean’s water to move around the world and also to transfer and redistribute

and also to transfer and redistribute

and also to transfer and redistribute heat with it but as we noticed the

heat with it but as we noticed the

heat with it but as we noticed the Arctic ice is melting due to rising

Arctic ice is melting due to rising

Arctic ice is melting due to rising temperatures and if this going to

temperatures and if this going to

temperatures and if this going to continue the Arctic ice will vanish

continue the Arctic ice will vanish

continue the Arctic ice will vanish and if that happened the ocean will stop

and if that happened the ocean will stop

and if that happened the ocean will stop moving and the water will rut that means

moving and the water will rut that means

moving and the water will rut that means all the sea creatures cannot breathe in

all the sea creatures cannot breathe in

all the sea creatures cannot breathe in it anymore and they will die and if the

it anymore and they will die and if the

it anymore and they will die and if the temperature got high enough to melt the

temperature got high enough to melt the

temperature got high enough to melt the Arctic Isis at that time no one on earth

Arctic Isis at that time no one on earth

Arctic Isis at that time no one on earth can resist it anymore not even we humans

can resist it anymore not even we humans

can resist it anymore not even we humans and not only this there are forests

and not only this there are forests

and not only this there are forests there are jungles there are rivers or

there are jungles there are rivers or

there are jungles there are rivers or grasslands a clean atmosphere that you

grasslands a clean atmosphere that you

grasslands a clean atmosphere that you are losing them all so if we lose these

are losing them all so if we lose these

are losing them all so if we lose these resources of life support at that time

resources of life support at that time

resources of life support at that time not oceans are not Moors can provide us

not oceans are not Moors can provide us

not oceans are not Moors can provide us life so as it seems the solution for

life so as it seems the solution for

life so as it seems the solution for Humanity is to save earth first and to

Humanity is to save earth first and to

Humanity is to save earth first and to maintain it livable to do that we have

maintain it livable to do that we have

maintain it livable to do that we have to depend on renewable energy more and

to depend on renewable energy more and

to depend on renewable energy more and to take care of the earth nature more

to take care of the earth nature more

to take care of the earth nature more and try to realize or to revive those

and try to realize or to revive those

and try to realize or to revive those areas that have been dirt or turned into

areas that have been dirt or turned into

areas that have been dirt or turned into deserts like why would have only 200

deserts like why would have only 200

deserts like why would have only 200 years left a free try

years left a free try

years left a free try if we care we can maintain the earth

if we care we can maintain the earth

if we care we can maintain the earth forever why when a country gets a

forever why when a country gets a

forever why when a country gets a problem all their supreme leaders will

problem all their supreme leaders will do their best to solve it or if one of

do their best to solve it or if one of

do their best to solve it or if one of your family member got sick immediately

your family member got sick immediately

your family member got sick immediately you will go to take him to the doctor

you will go to take him to the doctor

you will go to take him to the doctor but who will take care of earth if it

but who will take care of earth if it

but who will take care of earth if it got sick and the cause of the sickness

got sick and the cause of the sickness

got sick and the cause of the sickness is us and those who can save it or also

is us and those who can save it or also

is us and those who can save it or also us so the choice is ours to save it or

us so the choice is ours to save it or

us so the choice is ours to save it or not if we could save it at that time we

not if we could save it at that time we

not if we could save it at that time we can build any other place add a

can build any other place add a

can build any other place add a secondary home for humans and thank you
