PPT ON EARTH DAY

1. EARTH DAY
What does it mean to you?

2. MORE ABOUT ―Earth Day‖
Here are several general facts you should know on Earth Day:
•US Senator Gaylord Nelson was the first person to offer the
idea for Earth Day in 1969.
•20 million people were eager to participate in the 1st Earth Day
in 1970.
•200 million people came to Earth Day’s 20th anniversary in
1990.
•Theta is a green Greek letter that became the symbol of Earth
Day.
•John McConnell was the first person who offered to make Earth
Day a global holiday.

3. Green is the new black
We should all be very concerned about our future on Earth as
human beings.
Every year, the overall temperature has gone up slowly.
Eventually Earth will be too hot to live on, and the human race
will become extinct!
The best way to save our future is to start now.
Indians should be conscientious of global warming and
should watch their CO2 emissions because increasing CO2
concentrations means an increase in Earth's temperature.

4. FACTS about
Some fast facts about few simple yet important things we use
daily in our life such as:
• WATER
• FOOD
• ELECTRICITY
• PAPER
and their impact on environment

5. SOME FACTS about WATER
• Lakes & River provide 47% of our water
needs. The other 53% of water comes from
underground sources.
• How our water use affects our world.
• Water --------it’s so easy to take it for
granted.
• All you have to do is turn on the tap and
there it is – as much you want for anything
you want to do. Right?
• Let’s take a simple use of water ---Shower

6. LIFE STORY OF SHOWER
• The average urban household uses
94,000 gallons of water per year,
which is enough to fill 6 backyard swimming
pools.
• Heating water for a 10-minute shower creates 4.5 pounds of
carbon dioxide—one of the gases that contributes to global
warming.
• About 97% of the earth’s water is salt water, 2% is frozen in
glaciers and ice-caps, and only 1% is fresh water.
• There is no more fresh water on Earth now then there was
2,000 years ago, when the population was less than 3% of its
current size.

7. HOT SHOWER
• Your morning shower may not
seem like it uses a lot of water,
but that on shower uses more
then twice as much as the
average person in Rajasthan’s
village uses in an entire day.
• Before reaching your faucet, the water
was stored in your hot-water tank.

8. HOT WATER TANK
• Creating hot water takes a lot
of energy, and producing that
energy often creates carbon
dioxide.
• Cold water reaches the tank through
underground pipes that lead into your
house from a water-treatment plant.

9. TREATMENT PLANT
• Some ―Scrubber‖ chemicals,
such as aluminum and chlorine,
are added to remove dirt and
disinfect the water.
• The Clean water flows out, but
the leftover muck, called sludge,
usually ends up in a landfill.
• The water that is cleaned by the treatment plant
comes from above-ground and underground water
sources.

10. ABOVE-GROUND WATER
• Often, rivers are dammed to create
artificial lakes called reservoirs.
• The reservoirs provide a steady
supply of water and hydroelectric
power.
• The creation of reservoirs often affects
the plants and animals that had been
living in and around the rivers before
they were dammed.
• For example, some of the rare fishes which flow from
Himalayas are endangered because of the many dams that
block their migration route to and from the sea.

11. UNDER-GROUND WATER
• Aquifers are underground
layers of rock that stores water.
• Because of increased demand,
we’re using water from many
aquifers faster than it can be
naturally replaced.
• This lowers the level of water in the aquifer,
which often causes springs and streams to dry
up—disrupting the ecosystems that depend on

12. Take ACTION!
ANS:: Replace a showerhead
 Stepping into that hot shower every morning might
help you wake up.
But even more eye-opening is this fact:
You could get the same shower without draining so
much from your environment
or adding so much from your environment
or adding more carbon dioxide to the air.
Like most homes in INDIA, yours probably uses
over 94,000 gallons of water each year.
You could reduce that significantly by simply
changing your showerhead.
SO WHAT? --
Why Care?
“If I take
long
shower!”

13. LIFE STORY OF BREAD & MILK
• How producing of Bread & Milk
affects our world.
• Have you ever thought about what
goes into a bread and how milk
is produced.
• If you look a little closer you will
see it’s a lot more than just a hot
fresh bread – and we’re not talking about the butter on top,
either.
• Complete story of Bread & Milk’s life from the feedlot to
the fridge to the fast-food counter.

14. Quick Facts AboutBREAD & MILK
• Indians eat more then 72 billion
– that’s right, BILLION slices of bread / Roti every.
• An average Indian drinks 25 gallons of milk every year; imagine how
much milk we need in India for our entire population.
• It takes an average of 600 gallons of water to make quarter-pound of
bread.
• Think about it as 2,400 one-quart bottles of water, or enough to fill 11
bathtubs, for just one loaf of bread.
• A cow had to eat over 1.3 pounds of grain to produce that quarter-pound
of milk.

15. THE SACRED COW
• That means a single cow
could keep you drinking glass
of milk every day for five years.
• But to grow that cow, you have to grow a
lot of grain..

16. THE GRAIN
• Growing that grain isn’t doing
any favors for you or the environment.
• It takes lots of energy (fossil
fuels, such as gas and oil)
to plant and harvest the grain.
• Besides plenty of energy and water, it
also takes fertilizers and pesticides to
keep the grain growing and healthy. And
all those chemicals pollute the air, water,
and land.

17. THE LAND
• And a lot more land is needed
to grow the grass that cows
feed on before they get the
grain that fattens them up.
• Wherever there’s grass and grain and
lots of cows, there isn’t much room for
anything else-like birds, badgers,
bison,…other kinds of wildlife.

18. THE SOIL
• Erosion happens when rain washes soil off
the land and into places it shouldn’t be
– like streams, rivers, and lakes.
• Growing grain can cause erosion. And so
can overgrazing, when too many cows eat
too much grass and trample bare ground.
• Erosion washes away 1.2 pounds of soil.
• And that soil is gone forever, causing big trouble somewhere
downstream
• Erosion can also happen when people clear forest to make
more grazing land for cows. The soil washes away more
quickly because the trees aren’t there to hold it in place.

19. THE WATER
• All the water is enough to fill 11 bathtubs.
Why do much water?
Cows drink it.
Grain needs it to grow.
Factories even need water to produce
bread.
And then there’s water pollution from all the cow
manure that washes into streams and soaks into
the ground.

20. Take ACTION!
• ANS:: Well, you’re part of this
process, too--through your eating
and buying decisions.
 Eat one less sandwich per
week and substitute it by a fruit
and over the course of a year,
you save over 40,000 gallons of
water and prevent 300 pounds of
carbon dioxide from being
released into the air.
SO WHAT? --
Why Care?
“If I waste
some bread
and Milk!”

21. LIFE STORY A LIGHT BULB
• How flipping a switch affects our world –
―lighting things up‖, from your room to
the inside of your fridge
• You flip a switch and a light goes on.
Simple, right? Not really.
• There’s a lot more to turning on the light
than you may think.

22. BASIC Facts AboutBULB
• The electricity flows through the
bulb from wires hidden behind
the walls of your home.
• The switch closes a loop that
allows the electricity to circle the
bulb and heat up a filament,
which gives off the light.

23. THE WIRES
• The wires continue out to the
street, down the block, across
town, and all the way back to a
power plant.
• It’s a huge, interconnected
network.

24. THE POWER PLANT
• The hot water becomes steam, the
steam turns turbines ( Similar to huge
fans), and the turbines spin magnets
surrounded by wires.
• The magnetic field created by this
spinning creates a current in the wires,
which provides the electricity we use.
• Other power plants use nuclear
reactions to generate the heat they
need or wind or water power to turn the
turbines

25. THE COAL
• Many tons of coal are used to
make electricity.
• Coal is a fossil fuel that forms
over millions of years from plant
remains that have been
hardened and changed by time,
heat and pressure.
• And getting all that coal takes an
awful lot of mining.

26. THE COAL MINE
• Miners often go deep under
ground to dig coal.
• Other miners take coal from
closer to the surface, using
huge machinery to strip away rock
and soil.
• Unfortunately, all that tearing away and digging
leaves massive piles of waste that often end up
being dumped into valleys, where they can
seriously harm streams and the life found in them.

27. THE WATER
• All the water is enough to fill 11 bathtubs.
Why do much water?
Cows drink it.
Grain needs it to grow.
Factories even need water to produce
bread.
And then there’s water pollution from all the cow
manure that washes into streams and soaks into
the ground.

28. Take ACTION!
ANS:: Just one compact
fluorescent light build,
or CFL or tube light,
can save your parents
25 bucks on their
electricity bill.
More importantly, you can
prevent 1,572 pounds of
carbon dioxide from being released into the
atmosphere and contributing to global
SO WHAT? --
Why Care?
“How one light
bulb can make a
difference!”

29. Take ACTION!
 Therefore replace one standard light
bulb with a compact fluorescent light
bulb (CFL).
• By doing this, you prevent the release
of about 260 pounds of carbon
dioxide each year!
These bulbs are cooler than regular bulbs -not only in
appearances, but in temperature too.
The surface of a CFL bulb is warm, but won’t burn you
like regular bulbs.

30. LIFE STORY A PAPER
• In a min you will find out about how
making a paper affects our world in
many ways.
• From pulp mill to your Notebook.
• Paper is a huge part of your everyday
life. You use it in the books and
magazines you rad, the homework you
do, and the notes you pass in class.

31. BASIC Facts About Paper
• The average urban Indian resident uses about
750 pounds of paper a year.
• That means three people use more than a ton.
• To make that ton of paper:
– 24 trees are cut down
– 55,000 gallons of water are used
– 60 pounds of pollution are emitted
• When thrown out, a ton of paper uses three cubic
yards of landfill space-that’s about the size of a
compact car.
• The amount of electricity that goes into producing
one tons of paper would power your house for
two months.

32. THE CHOPPING AND CHIPPING
• The woods used to make paper
is taken either from virgin forests
or ―tree plantations‖ (which are
nothing like real forests).
• Once a tree us cut, it is sent to a
paper mill where it goes through
a chipper, which chews it up into
little pieces.

33. COOKING AND BLEACHING
• The digester boils the chip in
water and chemicals.
• This softens the wood into
slushy, sloppy pulp, which is
bleached with more chemicals.

34. WATER DOWN THE DRAIN
• This mixture is sprayed onto a fast-
moving mesh screen and is then
flattened and dried by another machine.
• The water that drains out is treated to
remove chemicals, but the process does
not completely clean the water.
• Some of the chemicals still make their
way into lakes and rivers.

35. CUTTING AND SHIPPING
• These rolls of paper are then put
through another machine that
can cut them into individual
sheets for our use.
• Once bundled, the paper is
shipped by truck and train to the
warehouses and stores where it
can be sold.

36. RECYCLE RECYCLE RECYCLE
• Paper makes up to 30% to 40% of
what’s found in landfills.
• Another option-recycling the paper
you use so it can come back in a
fresh form-helps save trees, energy,
and water.
• So does buying recycled paper in
school or office supply stores. (
You’ll know it by recycle symbol.)

37. Take ACTION!
• ANS:: Please Buy Recycled Paper
as making paper uses a lot of
trees, water, and energy.
If even one in ten students bought
recycled notebook this year, they
would save 60,000 tress and more
than 25 million gallons of water.
SO WHAT? --
Why Care?
“After all it is
just a paper”.

38. GLOBAL IMPACT
PAPER:
 If 23802 recycled Paper products Bought:
– 251,050 gallons of water saved
– 586,56 tress saved
– 51,290 pounds of CO2 prevented
BREAD & MILK:
 If 20936 sandwich skipped
– 16,357,860 gallons of water saved
– 120,801 pounds of CO2 prevented.
BULB:
 If 7019 light bulbs replaced
– 1,838,978 pounds of CO2 prevented.
WATER:
 If 2930 Showerheads replaced
– 12,502,301 gallons of water saved
– 735,430 pounds of CO2 prevented.
