Earth as water planet
• Earth is often referred to as `the water planet'.
• Earth is unique amongst planets of our solar
system because of its abundant water - in
oceans, atmosphere, glaciers and as fresh
water on land.
• Without water, life could not exist
• Ocean Water: The vast majority of water on the
planet is the salt water in the oceans and seas.
• Groundwater: Freshwater is stored in
underground aquifers. Water that enters an
aquifer remains for an average of 1,400 years!

Water on the earth
• Water is the main constituent of ecosystem & is
the basis of known life forms, including humans
• It was the basis of the origin of life on our planet
• It is essential to civil, agricultural & industrial use
• Men recognized since ancient times its
importance, and identified as one of the main
constituents of the universe, giving it a deep
symbolic value, found in major religions.

Significance of water
• Water is an integral part of life on this planet.
• It is an odorless, tasteless, substance that
covers more than three-fourths of the Earth's
surface.
• Most of the water on Earth, 97% to be exact, is
salt water found in the oceans.
• We can not drink salt water or use it for crops
because of the salt content & is heavy
• We can remove salt from ocean water, but the
process is very expensive.

Three forms of Water
• Solids: When water becomes very cold and
freezes it changes from a liquid to a solid state.
It has a definite form and shape.
• Liquids: When water takes the shape of its
container it is in a liquid form.
• Gases: When water is seen in a vapor form and
has no definite size or shape it is in a gas form.

Importance of water
• Organisms are composed 70%-95% of water
• Transport medium for food, oxygen, and other
things needed by cells
• Cellular medium within which biochemical
reactions can occur
• Supportive external environment for aquatic
organisms
• Means of support - Turgid plant cells
/Hydrostatic animal support systems

A precious natural resource
• We use water for drinking, irrigation, industrial
purposes and energy production.
Water use
• Agriculture and energy production - 80%
• Industry and public use - 20%
Usage
• As a nourisher of plant, animal & human life
• A bearer of food & drinks
• A prime element of industrial processes
• A medium for transportation

What kinds are there?
Availability
Water is essential to life on earth
• 97% of the water is salt water, and
is found in the oceans of the world.
• 3% of the water is fresh water on
which we depend.

Daily use of water
Fresh water is used as

Condensation
The Clouds form
Evaporation
vapor rises
Transpiration
The movement
through plants
Precipitation
The rain falls

• Saltwater evaporates from sun's energy
producing fresh water in clouds; leaves salts in
ocean.
• Water vapor cools and condenses to
precipitation over oceans and land.
• Runoff forms fresh water lakes, streams, ponds,
groundwater, and is held in plants and
transpired.

• Surface water is water collected on the ground
or in a stream, river, lake, wetland, or ocean

• Two main processes: precipitation &
evaporation
• Powered by energy from the sun
• Hydrologic cycle purifies water

The Hydrologic Cycle

Ground Water
• Ground water is located beneath the ground
surface in soil pore spaces and in the fractures
of rock formations.
• A unit of rock or an unconsolidated deposit is
called an aquifer when it can yield a usable
quantity of water

Water & Earth
• What % of the Earth is made up of water?
• What % of water is Salt, Fresh, and Frozen?
• What sources and sketch to create 2 pie charts
• The Earth is made up of
approximately 70% water.
• 97% of that water is salt
water. Very little is water that
we use to drink & cook
• 2% of water is frozen.
• 1% of water is fresh water

Water & Body
• What % of our body is made up of water?
• Human body is made
up of ~ 60-70% water
• Medical source
documents that men
have 60% and women
have 50% water.

Water & Blood
• What percentage of blood is water?
• 92% of 55% which is 50.6%
• Blood is a specialized bodily fluid in animals that
delivers necessary substances such as
nutrients and oxygen to the cells and transports
metabolic waste products away from those
same cells.
• It is composed of blood cells suspended in a
liquid called blood plasma. Plasma, which
constitutes 55% of blood fluid, is mostly water
(92% by volume),and contains dissipated
proteins, glucose, mineral ions, hormones,

Water & Blood

Water need
• Using the following site, calculate how much
water your team should drink a day.
• http://nutrition.about.com/library/blwatercalculator.htm

Function of Water in body
• Identify main functions of water in the body’s
metabolic process.
• It delivers oxygen and nutrients to different parts
• It removes toxins and waste from the body
• Water also has other functions:
• Regulates body temperature through
perspiration
• Reduces friction between joints and facilitates
movement
• Acts as a cushion between organs to protect
• Facilitates normal functions of body processes.

Water & Body
• In what way the body lose water & How much?
• A person can live without food for several weeks
but life cannot last more than few days without
water . Human body is 60-70 % water. We take
water with food and drink, and lose it in urine, in
sweat, and in our breath (as water vapor)
• A person loses 1.89-2.83 lit of water every day
as a result of their normal body functions
• This much loss means if a person doesn't get
any fluids for about three days, they will die.
• 6-9 quarts (5.678-8.517 l) of water loss would
cause death.

Water & Body
• Recall how much water the average person
loses in one day through their urine, sweat, and
normal breathing.
• Percentage of overall water loss occurs when:
• Thirst is perceived.
• Strength and endurance decrease.
• Delirium and blurred vision become a problem
and you can not move.
• A person dies.
• Calculate the amount of water loss for each
based on the amount of water lost per day.

Water & Body
• In one day the person loses between 2 to 3
quarts of water through their urine, sweat, and
normal breathing. If a person doesn't replace
that lost water, then dehydration begins to
occur.
• At 1-2% dehydration, thirst is perceived. (.6-.9
quarts)
• At 5% dehydration, a person becomes hot and
tired, and strength and endurance decrease.
(1.5-2.25 quarts)
• At 10% dehydration, delirium & blurred vision
become a problem, can not move. (3-4.5 quarts)

Think About
• Imagine an extended shortage of fresh safe
drinking water at any time in your life
• People from many other countries think about
this every day. A shortage of fresh safe drinking
water is a daily problem

Other Water Facts
• 1.2 billion people lack access to safe water,
• ~one-sixth of the world's population lack access
to adequate sanitation services.
• 6,000 die every day from diseases associated
with unsafe water, poor sanitation & hygiene.
• Unsafe water & sanitation cause an estimated
80 % of all diseases in the developing world.
• Women and girls tend to suffer the most as a
result of the lack of sanitation facilities.
• One flush of a Western toilet uses as much
water as the person in the developing world
uses for washing, drinking, cleaning & cooking.

Water facts..Continued
• Water use has grown at twice the rate of
population during the past century. The Middle
East, North Africa and South Asia are
chronically short of water.
• In developing countries, as much as 90 percent
of waste water is discharged without treatment.
• Over pumping groundwater for drinking water
and irrigation has caused water levels to decline
by tens of meters in many regions, forcing
people to use low-quality water for drinking.

Water facts..Continued
• Losses of water through leakage, illegal hook-
ups and waste amount to about 50 percent of
water for drinking and 60 percent of water for
irrigation in developing countries.
• Floods affected more than 75 percent of all
people impacted by natural disasters during the
1990s and caused over 33 percent of the total
estimated costs of natural disasters.

Problems using Groundwater
 Water table lowering
 Depletion
 Subsidence
 Saltwater intrusion
 Chemical contamination
 Reduced stream flows

Water and sanitation
• Investments in safe drinking water and
improved sanitation show an improvement in
human health and economic productivity.
• Each person needs 20 to 50 liters of water free
of harmful chemical and microbial contaminants
each day for drinking and hygiene.
• It’s a challenge to providing this basic service to
large segments of the human population.

Water - Globally

Learning Objectives
• To understand that water is a global issue and
not just within certain countries
• That lack of water is not the only issue in water
insecurity and stress
• Access to sanitation is linked to poverty
• Development can hinder water quality, access
and supply

Human water needs
• In the US usage in gallons/person/day
• A person needs about 1 gallon water/day for
hydration
• Personal use - 188
• Additional 657 used for irrigation, industrial use
• Total per capita use is about 2000
gal/person/day
• If world’s water supply were 100 liters, the
usable supply would be about 0.5 tsp
(teaspoon)
• US has highest per capita water withdrawal,
followed by Canada, Australia, Russia, Japan

contaminated some surface waters. (Salton
Sea)

Is that the whole world??

What can be done about this?

Emerging pattern
• The balance between human demand and
availability is precarious
• Access to clean water is not always guaranteed
when it should be a fundamental right
• Pop’n growth especially in the third world mean
prospects are not good.
• UN's world water development report

Millennium Development Goals
• In 2000 had a target to halve by 2015 the
proportion of people without access to
sustainable water supplies
• By 2005 only 12% of developing countries had
managed to do this
• In some LEDC’s fresh and waste water aren’t
even separated. (Cholera and dysentery)

How water is used
• In the western US, irrigation makes up 85% of
all water use
• 50% to grow food for livestock
• 35% to grow crops
• Not sustainable…cost of water is heavily
subsidized by the federal government

Key Areas-Direct Operations
• Virtually all business organizations utilize water
in the production of their goods & services, the
extent of use varies
• For instance, water-infrastructure companies
play a direct role in working with governments
and municipalities to manage water and
wastewater systems.
• In other cases, water is a primary ingredient in
an organization’s final product. Water is also
crucial in the manufacturing or development
process of many companies. In still others,
water is a primary resource in the supply chain.

• In areas of water stress, rapid industrialization
place significant demands on water resources.
• Therefore, we pledge to undertake the following
actions as appropriate & during the period
1.Conduct a comprehensive water-use
assessment (audits) to understand the extent to
which the company uses water in the direct
production of goods and services.
2.Set targets for operations related to water
conservation and waste-water treatment,
framed in a corporate cleaner production and
consumption strategy.

3. Seek to invest in and use new technologies to
achieve these goals.
4. Raise awareness of water sustainability within
corporate culture.
5. Include water sustainability considerations in
business decision-making – e.g., facility-siting,
due diligence, and production processes.

What have we learnt
• There is no life without water
• Extremely small % of fresh & usable water is
available for human being out of total stock
• That water is a global issue and not just within
certain countries
• That lack of water is not the only issue, but also
water insecurity and water stress
• Access to sanitation is linked to poverty
• Development can hinder water quality, access
and supply
• Using water carefully could minimize the
scarcity
