THE HOLE IN OUR
SKY
BY Y U Z U K A F U N A S A K A
Do you know about the ozone layer; a gaseous layer in
the upper atmosphere 15-30km above the Earth, which is
protecting our life by blocking a UV (ultraviolet)
radiation?
Well guess what…
WE are Destroying it!!
Before we move on to the reasons WHY we
are destroying the Ozone Layer, I would
like to explain the importance of Ozone
layer and the danger of the UV radiation
and the Ozone hole…
When summer comes nearby, you
hear your mama start saying “Put on
your sun cream before you burn
yourself from UV”
Well, what actually is “ultraviolet
radiation” ??
The pictures were the photos of some of the
serious diseases you can get from ultraviolet
radiation.
•Skin cancer: The uncontrolled growth of abnormal skin cells.
•Premature aging: The fast-tracked aging of skin
•Cataracts: A form of eye damage in which a loss of
transparency in the lens of the eye clouds vision. If left
untreated, cataracts can lead to blindness
•Immune suppression: The suppression of the body’s
immune system and the skin’s natural defenses. This could lead
to HIV too.
Over 2,000 people die from skin cancer each
year (data from UK)
12 to 15 million people become blind from
cataracts annually, of which up to 20% may
be caused or enhanced by sun exposure
according to WHO estimates
If there is no ozone layer and the UV radiation
hits our body directly, our cells die and it’s
impossible to live on lands.
Long long time ago, when there was no ozone
layer above Earth, it was impossible for living
things to live on lands because of the UV
radiation from the sun…
The photosynthesis of living things in the
water eventually created an ozone layer.
This made the living things to be able to live on
lands.
Here is a diagram about how ozone layer absorbs UV
radiation
The oxygen molecules use ultraviolet
radiation as a energy to form into
ozone molecules. The ozone
molecules then use ultraviolet
radiation to break apart into oxygen
molecules. And these oxygen
molecules use uv radiation to form
into ozone molecules again. This
process continues, and this is how
ultraviolet radiation gets “absorbed”
by getting used up by ozone
molecules.
But unfortunately, there are ozone-
depleting chemicals in this world
which are chemicals that destroy
the ozone layer
The ozone-depleting chemicals are mainly chlorine and
bromine. Chlorofluorocarbons (CFCs) is the main one.
Actually, originally there were not such
thing called “ozone-depleting chemicals”
in this world.
Well, where do they come from??
HUMAN
BEINGS
MADE
THEM
Ozone-depleting chemical
(chlorofluorocarbon) is mostly made from:
•Refrigerator
•Air conditioner
•Dry cleaning
•Some of the electric equipment
•Sprays
THESE CHEMICALS MAKE OZONE HOLE;
AUSTRALIA
The size was more than three and a half
times the size of Australia!
Because of the chlorofluorocarbon, The two
largest Antarctic ozone holes were recorded
in 2000 (29.8 million km2) and 2006 (29.6
million km2).
Antarctic ozone holes
in 2000 and 2016
Oh no!
USE THE
HYDROFLUOROCARBONS INSTEAD
UP TO SEVERAL
CENTURIES
PROBLEM IS
NOT SOLVED
, IF WE ALL THINK
THAT THE OZONE HOLE WILL SAFELY HEAL AND USE
THINGS THAT PRODUCES HYDROFLUOROCARBONS AND
CFC WITHOUT THINKING, THE OZONE HOLE WON’T HEAL
SUCCESSFULLY
Now, I would like to explain what you can do to
help the ozone hole disappearance become a
reality quicker from my own solution.
1.Donation
Here is a website where you can make
change by donating and supporting the
scientists to develop a scientists-based
solution to solve environmental problems
which includes ozone hole problem.
http://www.ucsusa.org/global_warming/scie
nce_and_impacts/science/ozone-hole-and-
gw-faq.html#.V8qK_pN94dU
Please scroll all the way down this page and
you will find a donation section.
2.Use bus instead
of cars
I think this is the one of the most
famous and also effective solutions.
Smog is also one of the substances that
help ozone-depletion and most of them
are released from cars. So using bus
instead would be a big difference.
Riding a bicycle would be wonderful
since it does not release anything bad
and also becomes a good exercise.
3.Try Cutting down
the time you use
your air conditioner
Cutting down the time doesn’t mean that you should
stop using your air conditioner! It is said that if you
don’t use the air conditioner at all in mid summer, you
can get avid disease. So actually air conditioner is
pretty important! So what you can do to cut down the
time you use your air conditioner in summer is, you can
just try using electric fans and paper fans instead of air
conditioner just for the morning. Put ice packs inside
your pillow at night and by doing this you can cut
down the time you use your air conditioner at night. By
dunking towels in ice water you can use that wet towel
wisely to cool your neck.
4. Buy pesticide
free foods or
organic foods
Pesticides also includes lots of ozone-depleting chemicals!
So if you don’t want pesticides used, support pesticide free
foods and organic foods by buying them! If you think
organic foods are too expensive, here is a list of foods you
don't need to buy organic (foods that only contains little or
non-pesticides when they are made) :
• Asparagus
• Avocado
• Cabbage
• Cantaloupe
• Carrots
• Cauliflower
• Eggplant
• Grapefruit
• Kiwi
• Onion
• Mango
• Mushroom
• Papaya
• Pineapple
• Sweet corn
• Sweet peas
• Sweet
potato
• Watermelon
5.Buy non-toxic
paint sprays
We don’t want ozone-depleting
chemicals in our sprays! In fact, these
chemicals may damage your health
while using too. So see the details on
the back of the can before you buy your
sprays!
6.Eco-friendly
household chores
Supporting the ozone layer by doing eco-friendly
household chores is another good idea! There
are lots of electronic cleaning devices that
produces ozone-depleting chemicals. Your
nearest supermarkets should be selling some
kind of cleaning goods made out of natural
ingredients. Try using towels and clothes that are
no longer used to clean your floor. Try not to use
electronic devices for cleaning, and that would
make a big difference!
7.Think before
you buy
refrigerators!!!
Thinking before you buy is the most
important thing to do! Because the reason
why the ozone hole was made was because
we never thought if the things we’re buying
is eco-friendly or not! When you buy
refrigerators, consider if it uses lots of CFC
or hydrofluorocarbons. Thinking before
using is also very important. Always put this
in mind!!
THANK YOU!!
Thank you very much for reading this slideshow! I hope you
have understood the importance of fast-tracking the ozone
healing, and would help the the ozone layer by trying some of
the 7 solutions I told you! We have to remember that we only
have one planet where we can live, so we have to think about
our planet carefully. The world is counting on your effort! I
know you can do it!!
Please share this slideshow to your friends and tell them the
importance of fast-tracking the ozone healing!
Thank you so much,
Yuzuka Funaska

The hole in our sky ~7 things I suggest you can do to help ozone hole heal faster ~

  • 1. THE HOLE IN OUR SKY BY Y U Z U K A F U N A S A K A
  • 2. Do you know about the ozone layer; a gaseous layer in the upper atmosphere 15-30km above the Earth, which is protecting our life by blocking a UV (ultraviolet) radiation?
  • 3. Well guess what… WE are Destroying it!!
  • 4. Before we move on to the reasons WHY we are destroying the Ozone Layer, I would like to explain the importance of Ozone layer and the danger of the UV radiation and the Ozone hole…
  • 5. When summer comes nearby, you hear your mama start saying “Put on your sun cream before you burn yourself from UV” Well, what actually is “ultraviolet radiation” ??
  • 6.
  • 7. The pictures were the photos of some of the serious diseases you can get from ultraviolet radiation. •Skin cancer: The uncontrolled growth of abnormal skin cells. •Premature aging: The fast-tracked aging of skin •Cataracts: A form of eye damage in which a loss of transparency in the lens of the eye clouds vision. If left untreated, cataracts can lead to blindness •Immune suppression: The suppression of the body’s immune system and the skin’s natural defenses. This could lead to HIV too.
  • 8. Over 2,000 people die from skin cancer each year (data from UK) 12 to 15 million people become blind from cataracts annually, of which up to 20% may be caused or enhanced by sun exposure according to WHO estimates If there is no ozone layer and the UV radiation hits our body directly, our cells die and it’s impossible to live on lands.
  • 9. Long long time ago, when there was no ozone layer above Earth, it was impossible for living things to live on lands because of the UV radiation from the sun… The photosynthesis of living things in the water eventually created an ozone layer. This made the living things to be able to live on lands.
  • 10. Here is a diagram about how ozone layer absorbs UV radiation The oxygen molecules use ultraviolet radiation as a energy to form into ozone molecules. The ozone molecules then use ultraviolet radiation to break apart into oxygen molecules. And these oxygen molecules use uv radiation to form into ozone molecules again. This process continues, and this is how ultraviolet radiation gets “absorbed” by getting used up by ozone molecules.
  • 11. But unfortunately, there are ozone- depleting chemicals in this world which are chemicals that destroy the ozone layer The ozone-depleting chemicals are mainly chlorine and bromine. Chlorofluorocarbons (CFCs) is the main one.
  • 12. Actually, originally there were not such thing called “ozone-depleting chemicals” in this world. Well, where do they come from??
  • 14. Ozone-depleting chemical (chlorofluorocarbon) is mostly made from: •Refrigerator •Air conditioner •Dry cleaning •Some of the electric equipment •Sprays
  • 15. THESE CHEMICALS MAKE OZONE HOLE; AUSTRALIA
  • 16. The size was more than three and a half times the size of Australia! Because of the chlorofluorocarbon, The two largest Antarctic ozone holes were recorded in 2000 (29.8 million km2) and 2006 (29.6 million km2). Antarctic ozone holes in 2000 and 2016
  • 19.
  • 22. , IF WE ALL THINK THAT THE OZONE HOLE WILL SAFELY HEAL AND USE THINGS THAT PRODUCES HYDROFLUOROCARBONS AND CFC WITHOUT THINKING, THE OZONE HOLE WON’T HEAL SUCCESSFULLY
  • 23.
  • 24.
  • 25. Now, I would like to explain what you can do to help the ozone hole disappearance become a reality quicker from my own solution.
  • 27. Here is a website where you can make change by donating and supporting the scientists to develop a scientists-based solution to solve environmental problems which includes ozone hole problem. http://www.ucsusa.org/global_warming/scie nce_and_impacts/science/ozone-hole-and- gw-faq.html#.V8qK_pN94dU Please scroll all the way down this page and you will find a donation section.
  • 29. I think this is the one of the most famous and also effective solutions. Smog is also one of the substances that help ozone-depletion and most of them are released from cars. So using bus instead would be a big difference. Riding a bicycle would be wonderful since it does not release anything bad and also becomes a good exercise.
  • 30. 3.Try Cutting down the time you use your air conditioner
  • 31. Cutting down the time doesn’t mean that you should stop using your air conditioner! It is said that if you don’t use the air conditioner at all in mid summer, you can get avid disease. So actually air conditioner is pretty important! So what you can do to cut down the time you use your air conditioner in summer is, you can just try using electric fans and paper fans instead of air conditioner just for the morning. Put ice packs inside your pillow at night and by doing this you can cut down the time you use your air conditioner at night. By dunking towels in ice water you can use that wet towel wisely to cool your neck.
  • 32. 4. Buy pesticide free foods or organic foods
  • 33. Pesticides also includes lots of ozone-depleting chemicals! So if you don’t want pesticides used, support pesticide free foods and organic foods by buying them! If you think organic foods are too expensive, here is a list of foods you don't need to buy organic (foods that only contains little or non-pesticides when they are made) : • Asparagus • Avocado • Cabbage • Cantaloupe • Carrots • Cauliflower • Eggplant • Grapefruit • Kiwi • Onion • Mango • Mushroom • Papaya • Pineapple • Sweet corn • Sweet peas • Sweet potato • Watermelon
  • 35. We don’t want ozone-depleting chemicals in our sprays! In fact, these chemicals may damage your health while using too. So see the details on the back of the can before you buy your sprays!
  • 37. Supporting the ozone layer by doing eco-friendly household chores is another good idea! There are lots of electronic cleaning devices that produces ozone-depleting chemicals. Your nearest supermarkets should be selling some kind of cleaning goods made out of natural ingredients. Try using towels and clothes that are no longer used to clean your floor. Try not to use electronic devices for cleaning, and that would make a big difference!
  • 39. Thinking before you buy is the most important thing to do! Because the reason why the ozone hole was made was because we never thought if the things we’re buying is eco-friendly or not! When you buy refrigerators, consider if it uses lots of CFC or hydrofluorocarbons. Thinking before using is also very important. Always put this in mind!!
  • 40. THANK YOU!! Thank you very much for reading this slideshow! I hope you have understood the importance of fast-tracking the ozone healing, and would help the the ozone layer by trying some of the 7 solutions I told you! We have to remember that we only have one planet where we can live, so we have to think about our planet carefully. The world is counting on your effort! I know you can do it!! Please share this slideshow to your friends and tell them the importance of fast-tracking the ozone healing! Thank you so much, Yuzuka Funaska
