      97 percent of earths water is salty, 2 percent is locked up in snow and glaciers/ice, and less than 1 percent is used for household uses. You can conserve water by turning off the sink when brushing your teeth.

    4. V.D. Pd.8- Did you know that you need 3170 gallons of water to make 1 pound chocolate or that only 5% of the freshwter you use is for toilets,taps,and hoses at home? Cool! :)

      Of all the water on earth, 97.5 percent is contained within the oceans. 2 percent is fresh water and frozen water locked up in glaciers/ice. To conserve water, for example when you are doing the laundry, by matching the water level to the size of the load.

      The source of almost all fresh water is precipitation from the atmosphere, in the form of mist, rain and snow.

  2. D.P_P8_ Freshwater is the water used for drinking, agriculture(farming), industries, and mother nature. Less than 1 percent of water is available to us. Most of the water in the world is too salty for humans to drink. Fresh water is usually stored by glaciers and in the ground. Others places that are from the surface are the rivers, swamps, and lakes.

  5. L.I.-Pd.8- Freshwater is sanitary and is neccesary for survival. 4,800 people a day die from waterborne diseases. A way to help conserve freshwater is to reduce your water footprint. That means using less water per day! Try taking shorter showers.

  11. Freshwater is water that isn't salty when it is considered as a natural resource. Only 2.75 percent is fresh water out of the entire earth. We can help our many needs for water in a balanced way that is equal for everyone. We now have new knowledge,and community of people that is still growing, that are committed to saving our water. We can run our washing machines only when full, or adjust the water level setting.

  12. M.S.W.-Pd.8- Freshwater is for drinking, industry, agriculture, and, of course, nature. If there wasn't any freshwater in nature, most animals would die, therefore decreasing their populations. There are a few ways to conserve of supply of water. For example, we can turn off the water while we brush our teeth, take shorter showers, and don't constantly have the sprinkler going just to water the plants. Less than 1% of water is freshwater because 97% is salt water and another 2% is locked up by glaciers and ice caps.

  17. A.M.T-Pd.8- more than 97 percent is to salty to drink. More than one million people don't have clean water. Many people die from water-borne disease, which is very sad. All of our water sources are connected so we have to try not to pollute it. We overuse our water, we take it for granite. Things will get very bad if we don't take action now!:)

  18. S.M. Pd-7: Freshwater accounts for one fifth of the Earth and provides half of the drinking water.

  19. J.S.-Pd.7- 97% is salt water. 2% is locked up in glaciers and ice caps. Less than 1% is left for drinking,agriculture, industry, and nature. We over using it, over tapping rivers, and over pumping ground-water. Over a billion people don't have access to clean/safe water. While 4,800 people die every day from water-borne disease.

  21. CM PER 5: Saltwater, or salt water , is a geological term that refers to naturally occurring solutions containing large concentrations of dissolved, inorganic ions

  22. A.H.-Pd.8- Freshwater is incredibly scarce, as that it takes up only approximately 2.75% of the world's water. Yet we all use it like there is an unlimited supply. In fact, there is truthfully only about 1% of it available, because the rest is locked up within glaciers and ice caps. Without freshwater, countless amounts of species will go extinct. Most people do understand or notice the vast amount of water used in their daily life, like how they use about five gallons of water every minute when taking a shower, or the 1+ gallon(s) they use when flushing a toilet. Nor do they comprehend that all the water we have at the moment is all we have for the rest of our planet's life, as that the water was formed through ancient processes that cannot take place today. We must conserve supplies and not take freshwater for granted or future generations may be headed toward calamity. Saving water on a daily scale is relatively simple, and some ways to do so are taking quick showers, turning off the tap while brushing teeth, etc. Any act makes a difference, no matter what. What will be yours?

  27. A.C.-Pd.8- Freshwater takes up only about 2.75% of the world's water, so we need to be extremely cautious in how we use it.
    70& of the freshwater taken out of rivers, lakes, and aquifers is used for agriculture. Freshwater is critical to the global food supply. Even though this is helpful, there are many people that do not drink or bathe in clean/safe water.
    Three-tenths of a percent of our freshwater, or 31,341 trillion gallons, is in lakes, rivers, and wetlands. This amount includes the water in organisms and the atmosphere.

  29. M.R.-Per 5

    1. Choose outdoor landscaping appropriate for your climate. Native plants and grasses that thrive on natural rainfall only are best.
    2. Install low-flow showerheads and faucet aerators. Because you’re saving hot water, you’ll also reduce your energy bill.
    3. If you’re in the market for a toilet, buy a low-volume, ultra low-volume, or dual-flush model. 4.
    4. Run your dishwasher and washing machine only when full. 5.
    5. Eat a bit less meat, especially beef. A typical hamburger can take 630 gallons to produce. 6.
    6. Buy less stuff. Everything takes water to make. So if we buy less, we shrink our water footprint.
    7. Recycle plastics, glass, metals, and paper. Buy re-usable products rather than throw-aways, as it takes water to make most everything.
    8. Turn off the tap while brushing your teeth and washing the dishes. Shave a minute or two off your shower time.

  33. Freshwater is water that doesn't contain large amounts of salt and is usually inland. More than 97% of the Earth's water is salty and 2% of the rest is frozen. That means that less than 1% of the water is freshwater. We can conserve freshwater by taking shorter showers, turning off the sink when we brush our teeth, and do less loads of laundry.

  38. KH Pd. 5- Fresh water is natural water on the Earth's surface in ice sheets, ice caps, glaciers, ponds, lakes, rivers and streams, and underground. Less 3 percent of water is fresh water! To conserve fresh water, we can conserve water. For example, we can fix leaky faucets so that it doesn't get wasted.

  44. M.M.-Period 8- Freshwater is not salty water. 72% of the Earth's surface is made up of water. 97% of Earth's water sea water (salt water) and the other 3% is freshwater. 2% of that freshwater is not accessible to humans because of the fact that it is stored in glaciers and ice caps. The other 1% is safe for human use. Ways that water can be saved include: shorter showers, turning the faucet off while brushing your teeth, etc.

  46. 97% of the global water supply is found in the oceans, which are saline. A very small amount of salty water is also located in saline lakes. The remaining 3% is 'freshwater'. Permanent ice (such as glaciers) is the largest freshwater storage on Earth, accounting for about 2% of the total global supply. Freshwater is also found beneath the Earth's surface as groundwater (30% of the freshwater supply) and in surface water storages such as lakes, streams, swamps and marshes. Small amounts of freshwater are also stored in the soil, the atmosphere, and in biological organisms.

  47. A.D. Period 7- 97 percent of the Earth's water is salt water. 2 percent of water is in glaciers and ice caps. That leaves 1 percent of water which is left for drinking, baithing, or anything else we use it for. With one percent of water left for us, we need to conserve it for later generations.

  48. Much of the earth's water is found in glacial caverns. 3% of our water is fresh, but with so little, how can life be sustained for much longer. Other water-deprived countries have turned human waste into drinkable beverages. Also,if companies would stop dumping their products into streams and lakes, or there were less littering, we may be able to swim in our town's rivers.

  53. michellem pd.8 Fresh water is naturally occurring water on the Earth's surface in ice sheets, ice caps, glaciers, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams. Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term doesnt include seawater and brackish water but it does include mineral rich waters.

  56. Per. 2 Well over 97% of water is salted water from ocean(of course)and less than three percernt is fresh water .Sadly we can't get more but we can save more. Anyway my point being the water is from mostly rain and snow and hail and lastly ice glaciers.
