The True Culprit Behind Global Warming | Mohamed Elmorsi | TEDxYouth@SAIS


when I was younger I was told over 70%
of the Earth’s surface was covered in
water
he believed that 70% of the planet we
called ours is home to the biggest and
most diverse biome in the world growing
up I was thought it was crazy that
creatures like this and this are able to
exist in some of the deepest parts of
the ocean like in the Mariana Trench
almost 11,000 meters below the surface
able to survive under pressures that are
unimaginable for humans I mean I put my
head into the water for like a minute
and I get a headache it’s crazy
there sure is a terrifyingly astonishing
place but as I gradually come of age it
terrifies me it terrifies me to discover
that the number of ocean dead zones has
increased dramatically over the past
half-century and for those of you who
are unaware ocean dead zones are little
parts in the ocean that are oxygen
deprived due to human induced nutrient
pollution these places are so low in
oxygen that they’re not they’re no
longer able to support most marine life
underwater it breaks your heart doesn’t
it it breaks my heart to discover that
the Great Barrier Reef the world’s
biggest coral reef system is dying due
to coral bleaching in another very
consequence of what we’re doing to our
beloved planet all you need to
understand that global warming isn’t
something we’re foreseeing anymore
the globe has already warmed the ocean
is already dying our best hope right now
is to try and figure out ways to reverse
that is already been done I want you all
to ask yourselves am I really doing the
best that I can to help and yours are
going to be either one of two things I
don’t know in which case thanks agree on
this bail has been debate for yes in
which case all I think break to but
that’s probably not the right answer
and I know what some of your thinking
when I I recycled
I Drive a hydrant I think short quick
showers I ride a bicycle to school every
day and that’s fine look at me wrong if
you’re doing that that’s great keep
doing it you are making a positive
change but I asked you to just look into
it a bit more and I’ll explain but first
someone is in your quick survey you guys
don’t mind how many of you here have had
a burger in the last a month or so a bit
further
all right that’s a lot of people hey
dude I’ve had a couple burgers actually
the last one I really like burgers
they’re delicious but what if I told you
that it takes three thousand liters of
water and make one herb one beef burger
to put that into perspective this is how
much water and the average human drinks
every single month
that’s 18 litres of water by eating that
burger you just wasted about 167 times
amount of water you’re drinking on
average per month like I’m not trying to
I mean talk about Isis a bullying or
some more crazy facts 55% of all the
water in the United States alone is used
to raise animals also the 5% is used for
domestic purposes and on the global
scale about a third of the entire world
world
Quadra reserved it’s used for the meat
and dairy industry okay I’m not trying
to shame all of you here enjoys that
herder over my desire to tell you that
burgers are our main problem and that we
should stop eating burger than that’s
full stop all I’m trying to prove here
today is that with a little
reconsideration for our diets in our
lifestyles its arrows and its residents
of this country because maybe some day
wake up to a slightly less blazing hot
lady perhaps on a poster instead of a
blazing hot furnace so why why is it
that most people to this day are some
wondering the infer from a system that
fossil fuels are the main positive
global workers well the Food and
Agriculture Organization of the United
Nations put it one way saying that the
dramatic warming impact is highest for
carbon dioxide simply because it’s
concentration and a midpoint meter much
higher than that but the other gases and
this is pretty accurate the tropospheric
concentration of carbon dioxide that in
our atmosphere is at around if you
haven’t gained two parts per million
that’s a lot of carbon dioxide the
misconception arises when the actual
effects of these lingering greenhouse
gases in our atmosphere are scantily
discussed think methane for example a
very commonly heard of greenhouse gas
there’s a lot of your know about methane
pretty cool greenhouse gas second most
concentrated actually at around seven
just over 1700 parts per billion in our
atmosphere methane is actually commonly
produced by most animals here’s their
digestive process animal parts that mean
specific but what I’m sure a lot of you
aren’t aware of is that methane is
actually 21 times more effective in trap
in the atmosphere my carbon dioxide how
about nitrous oxide third most
concentrated and it’s actually mainly
produced by none other than you guessed
it cow poo animal manure 65% of all
nitrous oxide emissions and thanks to
animal manure and rose isn’t it that’s
the area remaining lost my train of
thought 65% of that is so I guess what I
guess I guess we get all the green I
guess what we don’t agree upon is that
carbon dioxide is really the most
concentrated greenhouse gas in our
atmosphere rather than the most
detriment and that’s secondary
greenhouse gases like methane and
nitrous oxide deserve a lot more of our
attention because they need a lot more
distress and this brings me to my next
point
animal agriculture ladies and gentlemen
this next figure is a little disturbing
to say the least
Heyman’s arm and consume over 56 million
animals every single year let that
undersink it relie 56 billion there are
so many animals on this planet that they
have to take a forty five percent of the
entire lives on earth
forty five percent they’re responsible
for 91% of Amazon rainforest destruction
and on top of that they like the poop a
lot
they really like the poop millions upon
millions of kilograms of animal
excrement are produced every single
minute and as animal excrement releases
nice offset in the
which I’m pleasantly informing you is
296 times more destructive than carbon
dioxide how much is it I’m sure a lot of
you aren’t even aware it really goes to
show how misinformed we are because I’m
sure a lot of you are even aware that
animal agriculture comes for 15 from the
51 percent of all greenhouse gas
emissions on the planet that’s more than
all the emissions released by cars
trucks planes and ships combined and
nobody’s doing anything about it
all maybe these photos interval vegans
they’re really pompous and they like to
rub it in your face
that done they’re a lot healthier and
they’re going to live a lot longer than
you I don’t like them either I mean look
I’m not going to stand there try and
convince all of you in a country like
this that ain’t get is a way to go
especially when this kind of food exists
in this country so yeah I don’t think
that’s possible
in fact I myself don’t believe that
going fully angin it’s the right way but
I do believe that just like we’ve taught
our children to conserve water by
turning off the faucet when they’re
brushing their teeth in the morning a
conservative lectricity by switching on
the lights when they’re not in the room
by trying to prevent pollution by using
the bicycle riding the bicycle to school
every day I think we can make a lot of
repair to our already broken atmosphere
for only already broken planets are
already dying notion if we just taught
our children the value of eating food I
think it’s absolutely crucial a years
ago 80% of the human that the average
human being
was made out of vessels and these people
without a doubt understood the value of
meat that of the others of the luxury of
eating and that’s why I believe if we
teach our children the true value eating
conserve teaching them to conserve their
eating habits conserve their diets I can
do a lot for this minor we can save our
oceans and we can save our diet and
Great Barrier Reef people need to be
informed about the true culprit behind
global warming ladies and gentlemen
you’ve just been informed of the true
culprit behind the warming thanks
