  1. Water Conservation By: Serena Matovich

  2. Water Supply • The Earth is 70 percent water. • The amount available for human consumption is less than one percent. • All other water is either fresh water that is frozen, not safe to consume, salt water in the water, or inaccessible. • 97.5 percent of the water on Earth is salt water. • 68.7 percent of all fresh water is frozen in ice caps and glaciers.

  3. Lack of Water Access • In Africa, there are 345 million people who don't have access to water • In developed countries (such as the United States and Europe), there are 10 million people without access to water. • There are 780 million people in the world that lack access to water.

  4. Water Related Disease • Every 21 seconds, a child dies from water related diseases. • Guinea Worm disease: occurs when drinking water is contaminated with Dracunculus larvae. • In 2002, there were 50,000 cases of Guinea Worm disease in 13 countries in Africa. • Typhoid: caused by a bacterial infection from eating or drinking contaminated things. • Every year, there are about 12 million diagnosed with typhoid.

  5. Water Scarcity • The amount of water there is never changes, thanks the water cycle. • There is the possibility that when water return to the Earth, it won't be return in the same place, or with the same quality or quantity. • Population, demand and climate are growing and changing.

  6. Water Changes Based on Climate • A climate that is warmer increases evaporation from the land and sea, and also allows more water to be held in the atmosphere. • For every degree in Fahrenheit the temperature rises , the water holding capacity in the atmosphere increases by about 4%.

  7. Water in Economics • According to the World Health Association, for every dollar invested in water and sanitation, there is an economic return of between 3 and 34 dollars.

  8. Recycling Wastewater • Wastewater has already been being recycled for agricultural and industrial purposes. • Places like Singapore and Windhoek, Nambia are already recycling wastewater for drinking purposes. • In Fairfax, Virginia they have been recycling wastewater since the 1970s and 5% of their daily water supply comes from purified wastewater. • Only 10% of wastewater comes from toilets. • The rest comes from showers, sinks, and laundry machines. • Purified wastewater is actually cleaner than water bought in store because of stricter rules for cleanliness.

  9. Water Reduction • Take showers instead of baths. • Never run the faucet continuously. • Use low-flow shower heads or an adjustable flow reducer. • Fix any leaks you may have.

  10. The Water Challenge • Founded by the Water Project. • Created for Schools (or classes), Churches, youth groups, or companies to participate. • Asks participants to only drink water from the tap for two weeks and then to donate the money they saved. • Over the past 2 months over 800 groups around the United States and Canada have signed up.
