  1. Water, water … everywhere?

  2. Water…… • Water, water everywhere, but not a drop to drink …???? • There is a lot of water in the world, BUT… • 97% of it is in the oceans • 2% is locked in glaciers • Leaving only 1% for all of the land based plants, animals, and 7.4 billion humans to survive on!

  3. From our lessons focusing on water, you will: • Hopefully gain a greater appreciation of the fragilityof Canada’s fresh water supplies • Develop an understanding of the value of Canada’s water • Consider your roles as ‘stewards of the earth’ and your responsibilitiesas water consumers

  4. To get us there, you will investigate these questions: • How much water do you and your family use each day? Are you a ‘water waster’? • How extensive are Canada’s water resources? • What water issues affect Canada today? (Walkerton, water diversion projects, the loss of wetlands)

  5. Looking at Natural Resources: • Renewable resource  a resource that can replace themselves even after they have been used • Non- Renewable resource resources that are gone once they have been used up. • Flow Resource  resources that are replaced naturally whether or not human use them

  6. Canada is home to how much of the world’s fresh water supply? • 20% • 1 out of every 3 Canadians rely on the Great Lakes for their water • More than 3 billion liters of untreated sewage is dumped into our waterways every year by 21 cities across Canada • Less than 3% of the water produced at a large municipal water treatment plant is used for drinking

  7. Human Activities … Food for Thought • It requires 10 litresof water to manufacture 1 litre of gasoline • It requires 300 litresof water to produce 1 kilogram of paper • It requires 1000 litresof water to grow 1 kilogram of potatoes • The average Canadian home owner doubles their daily water use in the summer months in pursuit of a lush, ‘green’ lawn

  8. Personal Usage:Household Water Use – Did you KNOW? • Clothes washer – 230 L / use • Bath – 130 L / use • Dishwasher – 65 L / use • Shower – 25 L / minute • Toilet flush – 20 L / use • Water from a faucet – 12 L / minute

  9. Which country do you think is the largest consumer of water? • #1 United States – 425 litres / day • #2 Canada – 330 litres / day • #3 United Kingdom – 200 litres / day • #4 France – 135 litres / day • #5 Israel – 135 litres / day • Rural India – 35 litres / day

  10. Water Reality ------- YIKES!! • So in Canada we use 330 L/per day but this does not take into consideration agriculture, mining, manufacturing , cooling, electrical power generation, and municipal water use. • With ALL of these activities the per person usages rises to 4500 L/ per person per day!!!!! • Making Canadians the 2nd largest consumer

  11. Many people in the world view water as a resource more valuable than gold …

  12. Toilet Talk …

  13. The Toilet House

  14. The TOILET House • It has a steel, white concrete and glass house, with a symbolic opening in the roof, said the World Toilet Association in a statement. The house is a 419sq m structure with two bedrooms, two guestrooms and other rooms, the two-storey house of course features three deluxe toilets. Unlike the giant “toilet” in which they are located, they will not be see-through affairs. If you would like to visit this house you can go to Suweon, 40km south of Seoul, South Korea.

  16. Walkerton, Ontario – E-Coli Tragedy • The Walkerton Tragedyis a series of events that accompanied the contamination of the water supply of Walkerton, Ontario, by E. coli bacteria in May 2000. • Town water supply was operated by two brothers, both who had no formal training • The water supply became contaminated with the highly dangerous strain of E. colibacteria, from farm runoff into an adjacent well that was known for years to be vulnerable to contamination. • The town ordered a boil advisory alert • In the end, 7 people died, 2500 became violently ill

  23. Every river has a beginning and an end, but a lot of different things can go on in between! The things we do can affect the health of our rivers. A RIVER PUZZLE

  24. YOUR CHALLENGE: TO MAKE A HEALTHY RIVER THAT EVERYONE CAN LIVE WITH FOR A LONG, LONG TIME! • Cut out the puzzle pieces. • Put the source piece at the top. • Put the mouth piece near the bottom. • Sort the other pieces into categories: nature, urban, agriculture, industry, recreation, power • Plan your RIVER

  25. THINGS TO CONSIDER: • What can happen to a river when a factory is nearby? • What can happen when a town or city is close to a river? • Where along a river would water be clean for swimming or fishing? • Does farming affect the water in a river? • Could building a dam change the watershed or the way the water flows?
