In <br />1967 Americans used 370 trillion <br />gallons per day, and it is estimated that <br />in the year 2000 Americans are <br />ex.pected to use 1 Quadrillion gallons per <br />day. <br />There are 326,07.tooo cubic miles of <br />water in the world found in oceans. ice <br />fields, lakes, rivers. underground, and <br />humidity. <br /> <br />A cubic mile contains 1.1 trillion gallons <br />which is more water than the U.S. will <br />need every day by the year 2000. and is <br />three times as much as we use today. A <br />cubic mile would drench all of Ne.... <br />England by an inch of waler and would <br />flood Connecticut fa a depth of one foot. <br /> <br />317 million cubic miles are in the seas, 7 <br />million cubic mires are in polar icecaps <br />and glaciers. 1 million in ground water <br />more than a half mile deep, 1 million in <br />ground water less than a half mile deep, <br />30,000 in lakes, 16.000 in surface soil, <br />and 300 cubic mites in rivers and streams. <br /> <br />A city d,veUer uses ,In average of 150 <br />gallons a day, but can survive on 5 to 6 <br />pints. <br /> <br />It takes 18a,500 gallons to make a ton of <br />paper; 770 gallons to refine one <br />barrel of petroleum; 600,000 gallons 10 <br />make a ton of synthetic rubber; 25,000 <br />gallons to make a ton of steel; 300 <br />gallons to make one Io..1f of bread; and 4,000 <br />gallons to provide one pound of beef. <br /> <br />WATER USE IN UNITED STATES <br />Billions of gallons per day; <br />1967 1980 <br />32 39 <br />73 115 <br />119 162 <br />148 178 <br /> <br />Public Water Supplies <br />Industry <br />Steam Power Plants <br />Agriculture <br /> <br />There is the same amount of water on <br />earth today as when it was crealed 3 <br />billion years ago. It is estimated that one <br />billion tons of sediment are ,vashed into <br />the seas each year; sufficient to bury <br />Washington, D.C. under 10 feet <br />Hydrological Cycle: <br />1. \Vater on earth surface is heated and <br />evaporates. <br />2. Evaporated water rises, cools, (arms <br />clouds. <br /> <br />;~-1\:.; <br /> <br />3. Particles in clouds grow until they fall <br />as snow or rain. <br />4. Some rain or snow soaks into the <br />earth. <br />5. Some rain and snow falls into <br />streams, lakes, and oceans. <br /> <br />Hydrological cycle has no beginning _ <br />no end. <br /> <br />At any given moment 3,100 cubic miles <br />remain floating on douds. equivalent to <br />one inch of rain over the entire earth <br />every two weeks. <br /> <br />Each year 95,000 cubic miles of <br />moisture ascends inlo the atmoshpere; <br />71,000 of which falls back into the sea <br />and oceans; 15,000 strikes land, and the <br />remainder falls into lakes, rivers. ete. <br /> <br />One acre of corn may deliver 4,000 <br />gallons per day into the atmoshpt:>re. and <br />one cottonwood tree may deliver 1,500 <br />gallons per day. <br /> <br />There is enough water locked up in the <br />Antarctic Icecap 10 feed the Mississippi <br />River for 50,000 years. The melted ice <br />could match flow of all rivers (or about <br />800 years. <br /> <br />At anyone time, the rivers contain only <br />about 1/100th of one percent of water <br />on the globe. <br /> <br />The amount of water underground is <br />3,000 limes larger than all the water in <br />all the rivers in the world, and 20 times <br />larger than in all lakes or inland seas, <br /> <br />Human blood is 80% 10 90% water; <br />muscles about 75% and bones 20%. <br />Each day man loses 8 pints of water and <br />can suffer to lose no more than 1/10th <br />of the water supply in the body before it <br />becomes fatal. 2/3 of the human body <br />consists of water. Bread contains 35% <br />water; meats up to 70% and fruits <br />(tomato) up to 95%. <br />
