Building An Earthship | Rubén Cortés | TEDxYouth@KL


[Music]

[Laughter]

hello so I was told I should be careful

because there’s bird poop on the stage

so some of you might know I am the only

non Malaysian speaker today so I’ve come

from Mexico

therefore apologies with my accent at

some point is not so clear and the last

time I was in a public speaking event a

friend of mine sent me a message saying

if everything goes wrong or if anything

goes wrong just add speaking Spanish

that would mail the ladies down today a

friend of mine is sitting in the

audience and she texts me if all goes

wrong just take off your shirt so I hope

I can finish my presentation with all my

clothes on right um so today we’re

talking about the future for me we

cannot talk about the future without

talking about sustainability and if you

ask me where do I see the future I see

it right here right now in front of me

how many of you are younger than 30

years old that’s exactly my point

the big majority of you are really young

and you have all this energy and you

have so many things ahead of you and

very important you have ideas great

ideas and these ideas are going to shape

the future not just of Malaysia but the

future of humanity there’s things that

we need to consider when we talk about

the future so all the things just like

in nature are interrelated so when we

talk about the future we need to

consider the world population how many

of us are living in this planet the

human needs what do each of us need to

stay alive we need to consider how are

we supply in these things to all of us

and finally the impact that this has on

that beautiful planet that keeps us

alive everything is interrelated

so let’s start with war population we

know that we are more than 7.3 billion

people in the world and still

reproducing more and more we expect to

have more than 10 billion people living

in this planet by the year 2100 even

though the birth rates are decreasing we

know that the total population is

increasing because when development

happens also death rates decrease the

perfect example we have it in countries

like Germany Sweden where people are

reproducing less correct but with more

development the total rate still

increases they are reproducing less but

they are still reproducing so we know

we’re going to be a lot more people in

the planet and all of us have certain

basic needs

we all need food water shelter housing

we need sanitation and very important

like some of the other speakers have

already mentioned we’re all going to

need energy to keep us alive to keep our

industry is going so let’s talk about

these separate things food we know that

as countries develop the diets changes

well so we’re talking about more people

with changing diets

this means countries that used to

consume more starch base things like

rice now they’re moving into more dairy

and meat and don’t forget that to

produce 1 kg of rice takes about 3000

liters of water to produce 1 kg of beef

takes more than 15,000 liters of water

this is what we call beer total water

so some of you only keep in mind yeah

but I only consume 2 to 4 liters of

water a day correct for the beautiful

water everything that you consume all

the meat all the cotton in your shirts

there was a lot of water that was

required to produce those goods and

services so we know that the food demand

is going to increase considerably in the

future food is related to water like

we just explained and water cannot be

taken separately without talking about

sanitation we know that we have issues

with sanitation 80% of the developed

developing countries put the sewage back

into rivers and oceans without treating

it properly we know that this is killing

the species there and we’re basically

polluting the same water that we need to

survive in this planet we are destroying

the things that keep us alive we know

that an increasing amount of population

also means sorry also means that there’s

going to be a lot of housing required

the way we supply the housing today is

based on a very inefficient model that

number one is unaffordable to many and

number two does not take care of the

people and the planet so people have to

inquire that that goes on for even three

generations and you have places like

here in Kuala Lumpur with occupant C

rates of 23% while you have people

living on the streets this system is

just not delivering results the other

thing that we have to consider talking

about the housing model is that

architecture develops pretty but pretty

useless boxes so when you buy a house

you have to plug in the energy you have

to plug in the water and you have to

plug your house to the sewage system

otherwise your house is useless and the

problem of this is that every time we

turn on the lights we turn on the air

conditioning we flush our toilet we are

trashing the planet polluting polluting

polluting and this is the kind of houses

we are still looking at in the future

obviously more houses more people more

food more water means more energy we’re

expecting the energy demand to increase

by more than 50 percent in the next 30

years and the big issue of this is that

80% of this

energy is going to be produced with

non-renewable sources like some of the

speakers already mentioned sources that

produce or put carbon out there we are

trashing our planet and the system that

we have designed to provide us with all

those needs is what we call the economy

today and for many years we have focus

entirely on the economic system what’s

the problem with this economy is based

on one main core idea growth if the

economy is not growing we talk about

crisis nobody wants to have crisis

crisis is bad if there’s a crisis

there’s no economic growth how do you

get economic growth consumption if you

look at the formula of the GDP is

consumption plus investment plus

government spending plus net experts in

a summary consume so they have convinces

that consuming is the answer to

everything you’re not happy

no worries go shopping there’s poverty

in your country you need growth there’s

inequality in your country you need

growth democracy is not working you need

growth growth is the peel that solves

every single problem now what is the

problem the biggest problem with this

this is based on a linear system so the

economic system that we have created is

based on two very wrong assumptions

number one that the natural resources

are infinite and number two that they

are out there for us humans to do

whatever we want with them they are all

there for us to take and waste as much

as we want and there’s a strong impact

on the environment the part of the

equation that we have forgotten there’s

a way to measure the impact that our

economic system has on the sorry on the

environment we call it the ecological

footprint every one of us has an

ecological footprint what this means is

everything that takes from the

environment to keep us alive the amount

of water the amount of land to produce

the cotton that we are wearing the

amount of forage that we need to filter

all that carbon the amount of oceans

that we need to take all that carbon

that we’re putting out in the air and we

can quantify that very accurately and of

course depending on what country you

live in

your ecological footprint could be

higher or lower this is this one this is

what it looks in terms of the planet

with people living in it an analogy to

explain it very simple is if you look at

the green part that’s the biological

capital all the forests all the oceans

all the water that we have to keep us

alive the red line is the consumption

that we have so we know that we have

already crossed the line if we explain

this in financial terms this the green

part is your the money the capital that

you have in your account if you are

inside the green area you are paying

your consumption with the interest

generated by the capital in your account

in the moment you cross the green path

you’re spending more money than your

capital is producing in terms of the

planet we are consuming more than what

our planet can provide and we have

crossed that line and we are consuming

more and more and more and we’re going

to be more people in countries that are

growing and growing and growing this is

just not sustainable to keep us alive

with the way we’re consuming today it

would take one-and-a-half planet Earth

what’s the problem with this we only

have one planet earth looking at a list

of countries with a Rica logical

footprint we see two things here

obviously it’s hard to read all the

names of the countries

but something that you can see is that

the big majority have crossed the line

another thing that we can analyze here

is that the more developed the country

the larger the ecological footprint of

the rabbit ins is but we all have been

told that we have to go that way

we have to consume more the other thing

we can see is that the largest part of

those columns is the carbon the carbon

that we’re putting out there and as we

have analyzed this is gonna continue

increasing so it’s just gonna get worse

and worse and worse let’s look at

Malaysia this is what has been happening

with Malaysia if you see Malaysia is

already consuming more than what the

country can provide so what how can that

work you import things you start

consuming things that have been produced

in another country so you don’t see the

impact you are just enjoying your

consumption if the whole world would

consume add Malaysian levels we will

need 3.5 planet earth and we are so

happy going shopping right why not

the impact that this has on the planet

in terms of animals is exactly this we

have killed 52% of the other animals

sharing the planet with us and this has

only been tracked from the 70s onwards

so we don’t even know if the impact is

even higher than this talking about

freshwater species is even worse 76% of

freshwater species are not coming back

we have killed them other generations

will never see them so we have to

understand how nature works and stop

following a model that is not working a

model that has threatened other species

and today is threatening our own

existence we have to understand how

nature works in a cycle

or in a linear system the best example

is analyzing how a tree works this

beautiful illustration by the local

artist Elena Moran explains how a tree

takes energy from the Sun without moving

without polluting and the tree takes

that energy and builds it into sugars

and things that are good for other

species like us and like other animals

and if no animal eats these fruits it

falls down to the ground gets covered by

leaves some water falls on it and it

becomes compost compost is good for the

tree itself and is good for all other

species of plants around it the tree

takes the carbon which is poison to us

and that’s how it grows it stores it in

a solid mass and that’s how a tree grows

the tree uses the energy filters the

water puts it back in the air in a very

pure form by doing transpiration and

evaporation and gives us as well

oxygen together with the water it’s a

perfect system amazingly adapted to this

planet that produces no waste and

produces only good things to other

species think about it humans are the

only species in the planet that produce

garbage something that no other species

can use and that now we are having

problems with it what you’re looking at

is an Earthship Michael Reynolds the

creator of Earthship biotech Terr was

tire of what the architects were doing

these useless boxes so he said we need

instead of building so many spaceships

let’s build health ships a house that

can provide people with water food

energy stable comfortable temperature

with zero carbon footprint

and the house that is built mainly with

natural materials and garbage these are

the kind of materials we use energy

biotech tur tires we take a whole bunch

of tires recycled tires garbage that

otherwise would be burned or thrown to

the oceans or whatever but you know

tires are so strong is rubber and steel

is the best building material you can

time its earthquake proof so we take

them we fill them up with dirt we pile

them up as words we plaster them and we

blasted them again

and make them look pretty we make them

look like this and that’s very

temperature efficient earthquake proof

and dirt cheap affordable this is what a

finish wall looks like then we take

bottles we take cans we pile them up we

these are bottles very temperature

efficient you get the natural light

passing through but not the heat good

insulation it looks beautiful and this

kind of concept is what I’ve been

promoting in Malaysia the first aid ship

in Malaysia is being built as we are

sitting here I just got some pictures of

the update I should be building but I

had to take a break to be here we’ve

been building for the last three months

the first ad ship in Malaysia this house

when it’s completed is going to capture

water from the rain is going to filter

it while producing food for its

habitants two houses in one community

center built with garbage and natural

materials and we are building it with an

orang asli community and I said with not

four we are not a charity where we give

people things for free we empower them

we teach them how to replicate these

systems we think that they can afford

with metals that they can replicate so

they don’t need to wait for us to go

back once we finish they know how to

replicate this with things they can

afford so the project is open to

volunteers we don’t charge anything and

people have asked me are you scared that

people will start replicating these and

then you lose your business and like

well if people start replicating this I

will be the happiest man in the world

this is what we want we want people to

start spreading this so we take

volunteers we don’t charge them anything

they come they learn how we do these

things and they help us build it I’m not

saying that building airships is the

solution the solution to all problems

but it’s a simple example of things that

we could all be doing we have to think

how are we going to live in this planet

in the future today we’re talking about

the future one thing we need to keep in

mind is that the economy was created by

us but we were created by nature nature

the planet does not belong to us we

belong to the planet we cannot talk

about the future if we trash that planet

which is what we have been doing we need

to wake up we need to grow up stop

behaving like a child in its early

development stages where it’s all about

me and mine and we have to think about

us ours all the species sharing this

planet with us we have to take care of

them because we depend on them as well

what are we going to do with all the

money in the world if there’s no fish in

the sea if there’s no oxygen in the air

and there’s no clean water to drink we

can have a whole bunch of rich countries

we die in population some scientists say

it’s too late already

we have doomed ourselves our system has

reached a position where even if we stop

all industry today there’s so much

carbon out there that we’re going to

start seeing climate change to a level

that

is going to go out of control life in

the planet is going to continue only

without humans so it’s our decision

I believe there’s hope I believe we you

sitting here have the power to change

this we just have to focus less on

finance and economics and more on the

real things nature the things that keep

us alive we have to study how the

systems work we have to understand them

and we have to spread the message I

believe there’s hope I believe you are

the hope

let’s build today for tomorrow thank you

very much [Applause]
