  1. 1. EARTH DAYWhat does it mean to you?
  2. 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 theidea for Earth Day in 1969.•20 million people were eager to participate in the 1st Earth Dayin 1970.•200 million people came to Earth Day’s 20th anniversary in1990.•Theta is a green Greek letter that became the symbol of EarthDay.•John McConnell was the first person who offered to make EarthDay a global holiday.
  3. 3. Green is the new blackWe should all be very concerned about our future on Earth ashuman beings.Every year, the overall temperature has gone up slowly.Eventually Earth will be too hot to live on, and the human racewill become extinct!The best way to save our future is to start now.Indians should be conscientious of global warming andshould watch their CO2 emissions because increasing CO2concentrations means an increase in Earths temperature.
  4. 4. FACTS aboutSome fast facts about few simple yet important things we usedaily in our life such as:• WATER• FOOD• ELECTRICITY• PAPERand their impact on environment
  5. 5. SOME FACTS about WATER• Lakes & River provide 47% of our waterneeds. The other 53% of water comes fromunderground sources.• How our water use affects our world.• Water --------it’s so easy to take it forgranted.• All you have to do is turn on the tap andthere it is – as much you want for anythingyou want to do. Right?• Let’s take a simple use of water ---Shower
  6. 6. LIFE STORY OF SHOWER• The average urban household uses94,000 gallons of water per year,which is enough to fill 6 backyard swimmingpools.• Heating water for a 10-minute shower creates 4.5 pounds ofcarbon dioxide—one of the gases that contributes to globalwarming.• About 97% of the earth’s water is salt water, 2% is frozen inglaciers and ice-caps, and only 1% is fresh water.• There is no more fresh water on Earth now then there was2,000 years ago, when the population was less than 3% of itscurrent size.
  7. 7. HOT SHOWER• Your morning shower may notseem like it uses a lot of water,but that on shower uses morethen twice as much as theaverage person in Rajasthan’svillage uses in an entire day.• Before reaching your faucet, the waterwas stored in your hot-water tank.
  8. 8. HOT WATER TANK• Creating hot water takes a lotof energy, and producing thatenergy often creates carbondioxide.• Cold water reaches the tank throughunderground pipes that lead into yourhouse from a water-treatment plant.
  9. 9. TREATMENT PLANT• Some ―Scrubber‖ chemicals,such as aluminum and chlorine,are added to remove dirt anddisinfect the water.• The Clean water flows out, butthe leftover muck, called sludge,usually ends up in a landfill.• The water that is cleaned by the treatment plantcomes from above-ground and underground watersources.
  10. 10. ABOVE-GROUND WATER• Often, rivers are dammed to createartificial lakes called reservoirs.• The reservoirs provide a steadysupply of water and hydroelectricpower.• The creation of reservoirs often affectsthe plants and animals that had beenliving in and around the rivers beforethey were dammed.• For example, some of the rare fishes which flow fromHimalayas are endangered because of the many dams thatblock their migration route to and from the sea.
  11. 11. UNDER-GROUND WATER• Aquifers are undergroundlayers of rock that stores water.• Because of increased demand,we’re using water from manyaquifers faster than it can benaturally replaced.• This lowers the level of water in the aquifer,which often causes springs and streams to dryup—disrupting the ecosystems that depend on
  12. 12. Take ACTION!ANS:: Replace a showerhead Stepping into that hot shower every morning mighthelp you wake up.But even more eye-opening is this fact:You could get the same shower without draining somuch from your environmentor adding so much from your environmentor adding more carbon dioxide to the air.Like most homes in INDIA, yours probably usesover 94,000 gallons of water each year.You could reduce that significantly by simplychanging your showerhead.SO WHAT? --Why Care?“If I takelongshower!”
  13. 13. LIFE STORY OF BREAD & MILK• How producing of Bread & Milkaffects our world.• Have you ever thought about whatgoes into a bread and how milkis produced.• If you look a little closer you willsee it’s a lot more than just a hotfresh bread – and we’re not talking about the butter on top,either.• Complete story of Bread & Milk’s life from the feedlot tothe fridge to the fast-food counter.
  14. 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 howmuch milk we need in India for our entire population.• It takes an average of 600 gallons of water to make quarter-pound ofbread.• Think about it as 2,400 one-quart bottles of water, or enough to fill 11bathtubs, for just one loaf of bread.• A cow had to eat over 1.3 pounds of grain to produce that quarter-poundof milk.
  15. 15. THE SACRED COW• That means a single cowcould keep you drinking glassof milk every day for five years.• But to grow that cow, you have to grow alot of grain..
  16. 16. THE GRAIN• Growing that grain isn’t doingany favors for you or the environment.• It takes lots of energy (fossilfuels, such as gas and oil)to plant and harvest the grain.• Besides plenty of energy and water, italso takes fertilizers and pesticides tokeep the grain growing and healthy. Andall those chemicals pollute the air, water,and land.
  17. 17. THE LAND• And a lot more land is neededto grow the grass that cowsfeed on before they get thegrain that fattens them up.• Wherever there’s grass and grain andlots of cows, there isn’t much room foranything else-like birds, badgers,bison,…other kinds of wildlife.
  18. 18. THE SOIL• Erosion happens when rain washes soil offthe land and into places it shouldn’t be– like streams, rivers, and lakes.• Growing grain can cause erosion. And socan overgrazing, when too many cows eattoo much grass and trample bare ground.• Erosion washes away 1.2 pounds of soil.• And that soil is gone forever, causing big trouble somewheredownstream• Erosion can also happen when people clear forest to makemore grazing land for cows. The soil washes away morequickly because the trees aren’t there to hold it in place.
  19. 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 producebread.And then there’s water pollution from all the cowmanure that washes into streams and soaks intothe ground.
  20. 20. Take ACTION!• ANS:: Well, you’re part of thisprocess, too--through your eatingand buying decisions. Eat one less sandwich perweek and substitute it by a fruitand over the course of a year,you save over 40,000 gallons ofwater and prevent 300 pounds ofcarbon dioxide from beingreleased into the air.SO WHAT? --Why Care?“If I wastesome breadand Milk!”
  21. 21. LIFE STORY A LIGHT BULB• How flipping a switch affects our world –―lighting things up‖, from your room tothe 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 lightthan you may think.
  22. 22. BASIC Facts AboutBULB• The electricity flows through thebulb from wires hidden behindthe walls of your home.• The switch closes a loop thatallows the electricity to circle thebulb and heat up a filament,which gives off the light.
  23. 23. THE WIRES• The wires continue out to thestreet, down the block, acrosstown, and all the way back to apower plant.• It’s a huge, interconnectednetwork.
  24. 24. THE POWER PLANT• The hot water becomes steam, thesteam turns turbines ( Similar to hugefans), and the turbines spin magnetssurrounded by wires.• The magnetic field created by thisspinning creates a current in the wires,which provides the electricity we use.• Other power plants use nuclearreactions to generate the heat theyneed or wind or water power to turn theturbines
  25. 25. THE COAL• Many tons of coal are used tomake electricity.• Coal is a fossil fuel that formsover millions of years from plantremains that have beenhardened and changed by time,heat and pressure.• And getting all that coal takes anawful lot of mining.
  26. 26. THE COAL MINE• Miners often go deep underground to dig coal.• Other miners take coal fromcloser to the surface, usinghuge machinery to strip away rockand soil.• Unfortunately, all that tearing away and diggingleaves massive piles of waste that often end upbeing dumped into valleys, where they canseriously harm streams and the life found in them.
  27. 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 producebread.And then there’s water pollution from all the cowmanure that washes into streams and soaks intothe ground.
  28. 28. Take ACTION!ANS:: Just one compactfluorescent light build,or CFL or tube light,can save your parents25 bucks on theirelectricity bill.More importantly, you canprevent 1,572 pounds ofcarbon dioxide from being released into theatmosphere and contributing to globalSO WHAT? --Why Care?“How one lightbulb can make adifference!”
  29. 29. Take ACTION! Therefore replace one standard lightbulb with a compact fluorescent lightbulb (CFL).• By doing this, you prevent the releaseof about 260 pounds of carbondioxide each year!These bulbs are cooler than regular bulbs -not only inappearances, but in temperature too.The surface of a CFL bulb is warm, but won’t burn youlike regular bulbs.
  30. 30. LIFE STORY A PAPER• In a min you will find out about howmaking a paper affects our world inmany ways.• From pulp mill to your Notebook.• Paper is a huge part of your everydaylife. You use it in the books andmagazines you rad, the homework youdo, and the notes you pass in class.
  31. 31. BASIC Facts About Paper• The average urban Indian resident uses about750 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 cubicyards of landfill space-that’s about the size of acompact car.• The amount of electricity that goes into producingone tons of paper would power your house fortwo months.
  32. 32. THE CHOPPING AND CHIPPING• The woods used to make paperis taken either from virgin forestsor ―tree plantations‖ (which arenothing like real forests).• Once a tree us cut, it is sent to apaper mill where it goes througha chipper, which chews it up intolittle pieces.
  33. 33. COOKING AND BLEACHING• The digester boils the chip inwater and chemicals.• This softens the wood intoslushy, sloppy pulp, which isbleached with more chemicals.
  34. 34. WATER DOWN THE DRAIN• This mixture is sprayed onto a fast-moving mesh screen and is thenflattened and dried by another machine.• The water that drains out is treated toremove chemicals, but the process doesnot completely clean the water.• Some of the chemicals still make theirway into lakes and rivers.
  35. 35. CUTTING AND SHIPPING• These rolls of paper are then putthrough another machine thatcan cut them into individualsheets for our use.• Once bundled, the paper isshipped by truck and train to thewarehouses and stores where itcan be sold.
  36. 36. RECYCLE RECYCLE RECYCLE• Paper makes up to 30% to 40% ofwhat’s found in landfills.• Another option-recycling the paperyou use so it can come back in afresh form-helps save trees, energy,and water.• So does buying recycled paper inschool or office supply stores. (You’ll know it by recycle symbol.)
  37. 37. Take ACTION!• ANS:: Please Buy Recycled Paperas making paper uses a lot oftrees, water, and energy.If even one in ten students boughtrecycled notebook this year, theywould save 60,000 tress and morethan 25 million gallons of water.SO WHAT? --Why Care?“After all it isjust a paper”.
  38. 38. GLOBAL IMPACTPAPER: If 23802 recycled Paper products Bought:– 251,050 gallons of water saved– 586,56 tress saved– 51,290 pounds of CO2 preventedBREAD & 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.
