WATER THE W OF A. F.E.W. WATER GUIDING QUESTIONS TO CONSIDER: 1) WHAT IS WATER AND HOW IS IT USED IN OUR WORLD? 2) WHAT MAKES WATER PLENTIFUL FOR SOME & SCARCE FOR OTHERS?

3) HOW CAN STRUCTURAL AND PERSONAL DECISIONS CONCERNING WATER SUPPORT SUSTAINABILITY? WATER: WHAT MAKES US STAND OUT IN THE COSMOS https://youtu.be/kxqbpPWTl6A WATER

TWO MOLECULES OF HYDROGEN, ONE OF OXYGEN CONSIDERED A RENEWABLE RESOURCE (DUE TO THE HYDROLOGICAL CYCLE) 97.5% OF EARTHS WATER = SALT, 2.5% = FRESH BUT . . . >1% IS AVAILABLE FOR FLORA AND FAUNA

S.E.E. THE WATER ISSUES: SOCIETY DEFINITIONS: ECONOMIC WATER SCARCITY: CAUSED BY A LACK OF INVESTMENT IN WATER RESOURCES (USUALLY B/C OF POOR INFRASTRUCTURE & AN UNEQUAL DISTRIBUTION OF WATER POTABLE WATER: DRINKABLE WATER IMPROVED SANITATION: FACILITIES THAT SEPARATE HUMAN WASTE FROM HUMAN CONTACT

S.E.E. THE WATER ISSUES: SOCIETY THE U.N. HAS STATED WATER IS A HUMAN RIGHT HEALTH: ~ 800 MILLION DONT HAVE ACCESS TO SAFE WATER 2.5 BILLION DONT HAVE IMPROVED SANITATION OVER MILLION KIDS DIE A YEAR OF DIARRHEA (88% caused by unsafe water); annual deaths dropping: 2.4 million 1990, 1.25 million 2013

COLLECTION TIME: WOMEN/GIRLS SPEND 200 MILLION HOURS DAILY COLLECTING WATER THIS IMPACTS FEMALE EDUCATION, FEMALE EMPLOYMENT, NATIONAL DEVELOPMENT WATER

S.E.E. THE WATER ISSUES: SOCIETY AGRICULTURE/LIVESTOCK: SHORTAGES WIPE OUT CROPS/ANIMALS, CAUSING FAMINE & FOOD SHORTAGES POLITICAL INSTABILITY: COUNTRIES FIGHT OVER WATER RIGHTS TO RIVERS (Nile = Egypt, Sudan, Kenya, & Ethiopia); WELLS/SPRINGS (East African Drought 2008-2011

warlords fought to control wellsall of this impacts delivery of international aid) http://e360.yale.edu/feature/when_the_water_ends_africas _climate_conflicts/2331 / S.E.E. THE WATER ISSUES: ENVIRONMENT #1 FORM OF WATER SCARCITY IS PHYSICAL WATER

SCARCITY: WHEN DEMAND FOR WATER IS GREATER THAN LOCAL RESOURCES CAN PROVIDE. CAUSES FOR THIS: EARTHS WATER NOT EVENLY DISTRIBUTED (geography) OVERUSE BY HUMANS (ARAL SEA) CONTAMINATION BY NATURAL DISASTERS/HUMANS (KATRINA & INDUSTRIAL WASTE) CLIMATE CHANGE (RAINFALL PATTERNS CHANGING)

WATER: SHRINKING OF THE ARAL SEA SOVIET DESIRE TO INCREASE COTTON YIELD LED TO IRRIGATION DEVASTATION. SHIPPING & FISHING

DESTROYED. PORT TOWNS ALSO DRIED UP S.E.E. THE WATER ISSUES: ECONOMY ALTHOUGH THE POOR HAVE LESS PIPED WATER CONNECTIONS THAN THE WEALTHY, SLUMS/OTHER LIKE PLACES PAY ~ 5-10 X MORE

FOR WATER FOOD PRICES RISE WHEN WATER IS SCARCE USES OF WATER: AGRICULTURE 70%, INDUSTRY 22%, DOMESTIC 8% WATER: A SNAPSHOT LOOK http://www.angelamorelli.com/water/

SINCE WATER IS TIED TO ENERGY USE, IT IS OFTEN HARD TO LOOK AT OBJECTIVELY EXS: WATER TO COOL NUCLEAR PLANTS, USE OF STEAM TO DRIVE TURBINES, HYDRO DAMS EXS: ENERGY TO ACCESS WATER: WELL PUMPS, DESALINATION PLANTS WATER SUSTAINABILITY: DOMESTIC

WATER USE VARIES DRASTICALLY WITHIN COUNTRIES, BUT WE ARE USING WAY TOO MUCH WATER, WAY TOO FAST #1. CUT DOWN TAP RUNNING TIME (BRUSHING TEETH) #2. LOW-VOLUME FLOW RATE TOILETS/SHOWERS #3. FIX LEAKS! (Avg. US home wastes _____ gallons yearly w/ one faucet drip); with a moderate toilet leak _______ monthly? Faucet: 10,000 gallons yearly; toilet 6,000 gallons monthly #4. WATER-SAVING APPLIANCES (dishwashers/washing machines) #5. USE RAIN BARRELS, CAR WASHES, XERISCAPING, KEEP

TRASH OUT OF LAKES AND STREAMS #6. EAT LOWER ON FOOD CHAIN, STOP USING PLASTIC WATER (3 liters to produce 1 liter), CONSIDER VIRTUAL WATER PRINT WATER SAVING VIDEO TIPS https://youtu.be/EQ21EMkLRFo Howcast saving water https://youtu.be/hLcKn1M5fRQ 10 tips https://youtu.be/jUUqYWnX8ls California tips
