PRIOR KNOWLEDGE
The water is the most important resource of the earth. It has many utilities
like: taking a bath, clean de dishes, to cook, to brush our teeth, for recreation, etc. People make power
plants, they use the water for making energy. We have to conserve water
because people is damaging it.

WHAT ARE WATER RESOURCES?
Water resources are sources of water that are useful or potentially useful to humans. Uses of water include agricultural, industrial, household, recreational and environmental activities. Virtually all of these human uses require fresh water.
![Page 6: 1)Introduction 2)Prior Knowledge 3)What is water resources? 4)How do people use water resources? 5)Why do we need water? 6)Why do we need to save the](https://reader034.vdocument.in/reader034/viewer/2022051516/56649da75503460f94a9356f/html5/thumbnails/6.jpg)
97% of water on the Earth is salt water, and only 3% is fresh water of which slightly over two thirds is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is mainly found as groundwater, with only a small fraction present above ground or in the air.Fresh water is a renewable resource, yet the world's supply of clean, fresh water is steadily decreasing. Water demand already exceeds supply in many parts of the world and as the world population continues to rise, so too does the water demand.
HOW DO PEOPLE USE WATER RESOURCES?

WHY DO WE NEED WATER?Water is probably the most important resource on Earth. We need to grow and stay alive. In fact, we could only live for a few days without drinking water. We also need water to grow plants and care for animals, cook our food, bath and brush our teeth, flush the toilet, and wash our clothes.

WHY DO WE NEED TO SAVE WATER?
Most of the Earth’s surface is covered in water. Ocean water is very salty. You can’t drink it or use it for growing plants, cooking food, bathing, or washing clothes. The water we use for these things is called freshwater. It comes from rain or snow that falls in rivers and lakes. It is also found stored in rocks beneath the ground. Some people don’t have enough freshwater where they live. It is important for everyone to conserve, or save, water so that there is enough for everyone.

WHAT ARE SOME WAYS TO CONSERVE WATER?
In the United States, each person uses about 50 gallons of water a day. When people use water, they often waste a lot. Very large amounts of water go down the drain without being used. To conserve water, try some of these ideas:
• Turn the water off while you are brushing your teeth or washing your face.
• Check your home and school for leaky faucets, and tell an adult if you find one that drips.
• Take shorter showers, and don’t fill the tub all the way when you take a bath.
• Don’t leave the garden hose on all night when watering plants.
• Make sure the dishwasher and washing machine are full each time your family does a load.

USES OF FRESH WATERUses of fresh water can be categorized as consumptive and non-consumptive (sometimes called "renewable"). A use of water is consumptive if that water is not immediately available for another use.
![Page 11: 1)Introduction 2)Prior Knowledge 3)What is water resources? 4)How do people use water resources? 5)Why do we need water? 6)Why do we need to save the](https://reader034.vdocument.in/reader034/viewer/2022051516/56649da75503460f94a9356f/html5/thumbnails/11.jpg)
It is estimated that 69% of worldwide water use is for irrigation, In some areas of the world irrigation is necessary to grow any crop at all, in other areas it permits more profitable crops to be grown or enhances crop yield. Aquaculture is a small but growing agricultural use of water. Freshwater commercial fisheries may also be considered as agricultural uses of water.
AGRICULTURAL

INDUSTRIALIt is estimated that 22% of worldwide water use is industrial.
Major industrial users include power plants, which use water for cooling or as a power source (i.e. hydroelectric plants), ore and oil refineries, which use water in chemical processes, and manufacturing plants, which use water as a solvent. The portion of industrial water usage that is consumptive varies widely, but as a whole is lower than agricultural use.

HOUSEHOLDIt is estimated that 15% of worldwide water use is for household purposes. These include drinking water, bathing, cooking, sanitation, and gardening.

RECREATIONRecreational water use is usually a very small but growing percentage of total water use. Recreational water use is mostly tied to reservoirs. Recreational usage may reduce the availability of water for other users at specific times and places.

ENVIRONMENTALExplicit environmental water use is also a very small but growing percentage of total water use. Environmental water usage includes artificial wetlands, artificial lakes intended to create wildlife habitat, fish ladders , and water releases from reservoirs timed to help fish spawn.

CONSERVING WATER

PROBLEM SOLUTION
That people waste water cleaning their cars.
Say to people that control the water using rags.
Some people when they go to the bathroom they left open the faucet of the sink.
Tell the people that don’t left the faucet of the sink open.
Some people when they are taking a bath they are soaping themselves they left the faucet open.
Tell people that don’t left the faucet open.
