“The State of the Planet” takes a brief look at four different
environmental topics: water issues, the threat of food shortages,
human population growth, and global warming. These issues are likely
to have a significant impact on the future well-being of Earth’s
environment and the people who depend on it for their needs and
wants. At the root of these issues is a dramatic human population
growth rate that is putting ever-increasing pressure on the Earth’s
resources and natural systems. Most of this growth is occurring
in the world’s poorer countries, putting enormous strains
on their water supplies and ability to feed their citizens. “State
of the Planet” discusses how food and water problems
are threatening the future of developing countries.
But environmental problems are also affecting
the United States; for example, “The State of the Planet” illustrates
how water shortages are threatening agriculture in the United States.
Population growth is also increasing in the United States,
and this is of major global significance because U.S. citizens,
on average, use far more energy and natural resources than people
elsewhere. Our energy consumption, chiefly our burning of the
fossil fuels coal and oil, is the main cause of human-created global
warming. As our numbers increase so will our environmental impact.
At present, global warming presents perhaps the most difficult and
serious environmental issue confronting the world today.
Yet, increasingly, people are focusing their commitment
and ingenuity on solving environmental issues, and “The State of the Planet” takes
a look at some of these. These examples serve as a beacon of hope
that ultimately we will learn to live in harmony with the planet’s
natural systems and ensure a bountiful future for us and for

This film takes a look at four critical environmental issues that
will have a large impact on your future: Human population growth,
water pollution and abundance, abundance of food, and global warming.
What do you know about these issues? (You can make a list of student
answers on the board)
From what you know now, how do you think your world will be in
40 years or so, as far as these issues are concerned?
What do you think the population of the world will be? Larger
or smaller? What impact will this human population have?
Do you think water will be cleaner, dirtier, or about the same
as today? Why or why not? Do you think you will have as much water
for your use as today?
Do you think there will be enough food for everyone in 40 years?
Why or why not?
What do you think the climate will be like? Will it be warmer
or colder or basically the same as today? What makes you think
Do you worry at all whether the world in 40 years will be able
to provide you or your children with the life that you want? Why
or why not?
Segment One Topic: Introduction
Segment One introduces the film, quoting several environmental
experts as they express their concerns about the issues raised
in the film.
Finding Segment One (Length: 3 minutes
and 3 seconds) Visual
and audio cues: Start when you see a sunrise and hear “Since
the first of time, before our ancestors
even thought of time....” Stop
when you hear “Perhaps it’s
best to start with numbersnumbers that
have literally shaped the human condition.”
Segment Two Topic: Threats Concerning Human Population Growth
It is hard to imagine the numbers of people on Earth as w e begin
the 21st Century. Today, roughly 6.3 billion people
live on the planet, each hoping to find enough food, water, clean
air, housing, employment, and recreation to live happy, healthy,
productive, and fulfilling lives. Our ability to take care of our
environment so that it will continue to take care of us, however,
has not kept pace with the increasing demands we have made upon
it. As a result, our exploding human numbers have brought with
them massive air and water pollution, soil erosion, and depletion
of forests, wildlife, and natural habitats. Massive poverty, hunger,
disease, and human misery have been the result.
Segment Two describes just how rapidly our numbers
have grown and what the consequences have been. The impact has been
particularly severe in the developing world. Our human population
in the United States, however, is also growing. This is significant
because the average American uses far more resources – food, energy,
wood, etc. – than the average citizen of a developing
country. Thus, we have a proportionally larger environmental
impact per capita, and this impact will influence the quality
of our future environment to a great degree.
Finding Segment Two (Length: 6 minutes
and 38 seconds) Visual
and audio cues: Start when you see a chart illustrating the
rate of human population growth and hear “From the
time of our prehistoric ancestors, it took until about 1800
for our planet’s population…..” Stop when
you hear “This
raises one of the most fundamental questions
of our time: can our planet provide our population
with even the basic necessities of life?”
- How long did it take for the human population to grow to one billion
people? (Answer: Perhaps one million years, or as long as our species, Homo
sapiens, has existed.) How long did it take to reach two billion?
(Answer: 125 years) How long did it take to reach four billion?
(Answer: less than 50 years) How long did it take to reach six
billion? (Answer: Only 25 years) What do you notice about the rate
of increase of human populations? (Answer: The rate of increase
has skyrocketed in the last 200 years.)
- How rapidly is our population increasing today? (Answer: Roughly
78 million people/year or 10,000 children being born during the
time this show was on the air)
- How large is Bangladesh, and how many people live there? (Answer:
Bangladesh is only the size of Wisconsin but contains roughly half
the people that live in the United States: around 145 million people!)
Until recently, what did the average family size used to be? (Answer:
Eight) What is it today? (Answer: Four) Why does the film say that
this happened? (Answer: Families are better able to control the
numbers of children they have, because education and birth control
devices are being supplied.)
- Many people and organizations believe it is crucial for the future
well-being of people and the environment to slow down the rate
at which human populations have been increasing. Is progress being
made? (Answer: Yes, the rate of human population growth has slowed
significantly in recent years. Today people predict that population
numbers will increase to 9.5 billion and then begin to slowly decrease.)
- Most population growth is occurring in developing countries. What
are the chances a baby born today lives in the United States or
another rich country such as Japan, Canada, Australia, or a European
country? (Answer: Over five out of six people on Earth live in
poor countries. If you happen to live in a rich country, you are
in a true minority. Statistically, you were much more likely to
be born in a poor country!)
- The population of the United States, however,
is also growing. Why does the film say that this is significant?
(Answer: Americans use far more natural resources and energy than
anybody else. As our numbers increase, we will therefore use up
more and more of the planet’s resources, which will have major
human and environmental consequences. For instance, we burn far
more coal and oil per capita to meet our energy needs. This is thought
to be the main cause of global warming. With more of us, we will
burn more coal and make global warming more severe, if we keep behaving
the way we do today.)
Segment Three Topic: Threats Concerning Water
An irreplaceable resource, all life on Earth needs ample clean
water to survive. There is no alternative. Unfortunately, both
the abundance and the quality of our water supplies are at risk.
This is creating problems around the globe. Increasing numbers
of people in developing countries are finding it difficult to find
enough clean water to drink. Waterways are continuing to choke
on human waste. Water-borne diseases, many of which can be easily
prevented, are afflicting millions of people in poor countries.
Natural wetlands are disappearing. And water supplies, even in
developed countries, are dwindling and threatening the future of
farmers around the world.
Segment Three looks at these issues and also highlights several
stories of human ingenuity in which water problems were successfully
confronted. These stories give us hope that we will ultimately
develop the commitment and the know-how to solve our water problems.
The challenges we face, however, are serious.
Finding Segment Three (Length: 22 minutes and 12 seconds)
and audio cues: Start when you see a scene of shallow ocean
water and hear “Though our planet is covered by an extraordinary
amount of water, over 97% is undrinkable seawater…” Stop
when you hear “What happens to water resources is going to
shape our future in ways that I don’t
think we can now easily imagine.”
Post -viewing Discussion
are three water problems that are affecting people in developing
countries? (Answer: water shortages,
water pollution, and water-related diseases)
- What water problem is afflicting farmers
in the United States? (Answer: water shortages) For what
two reasons does the film say this is happening? (Answer:
1. Human population increase, as along the Rio Grande River,
that is using increasing amounts of water; 2. Drawing down
the supplies of the Ogallala Aquifer under the Great Plains
faster than they can replenish themselves.)
are also destroying wetlands around the world. What are
three consequences, according
to the film? (Answer: 1. Loss of habitat for wild creatures;
2. Loss of a natural means of cleaning waterways; 3. Loss
of areas that protect human settlements from floods. The
film dramatically portrayed this last problem as floods
struck the upper Mississippi River.)
Segment Four Topic: Threats Concerning Food
human population growth in the last 100 years has occurred
in developing countries, and this has made it difficult for
many of them to feed their citizens. Pressure to increase
agricultural production has lead to such problems as soil
erosion, exhaustion of nutrients, and overgrazing of pastures.
These, in turn, make agriculture more difficult. The United
States and other countries produce enough food to feed the
world, but financial, political, and logistical obstacles
are preventing this food from getting to all of the people
who need it. As a consequence, perhaps 800 million people
are going to bed hungry every night. Segment Four briefly
summarizes this situation, and presents one case study – China – that
is achieving marked success in increasing
its food production and the number of its citizens who are
getting enough to eat.
Finding Segment Four (Length: 5 minutes and 26 seconds)
and audio cues: Start when you see a combine in a field
and hear “This raises another question of great concern for
the state of the planet.” Stop when you hear “It won’t
be easy, especially when an even greater
threat to the state of the planet may be
looming on the horizon.”
Post – viewing Discussion
to the film, what is the main food-production problem afflicting
the world today? (Answer: Food distribution, not food production.
We are growing enough food to feed the world’s
billions, but we are not always successful
at getting the food to the people who need it.)
- Why does the example of China give
us hope about feeding the world? (Answer: Until recently, China
used to experience severe famines that killed millions of her
citizens. Now very few go hungry, even though China has to
feed over 1.2 billion people.) What might be threatening China’s
success? (Answer: Economic pressure is causing China to expand
industrial production, so factories are taking over good farmland,
and skilled farmers are leaving their fields to work in them.)
Segment Five Topic: Threats Concerning Global Warming
our efforts to provide sufficient food and clean water to
growing human populations is the threat of global climate
change. Segment Five touches on this controversial notion,
presenting several lines of evidence that human activity
is actually causing Earth’s temperature to rise: heat
waves in cities around the world, melting glaciers, rising
sea levels, and the appearance of fish and animals where
they were previously unknown. The main cause of global warming
is thought to be the burning of fossil fuels, but since we
rely upon these fuels for most of our energy needs and since
countries such as China and India are increasing their fuel
consumption as they try to raise the living standards of
their citizens, confronting this growing threat promises
to be one of the most challenging tasks confronting us in
the 21st Century.
Finding Segment Five (Length: 5 minutes and 35 seconds)
and audio cues: Start when you see a summer scene in Chicago
and hear “A few years ago, Chicago was at the epicenter of
an extraordinary weather event.” Stop when you hear “In
a warmer and dryer world, they will need new ideas.”
Post – viewing Discussion
According to the film, what are four types of evidence that global
warming is occurring? (Answer: 1. receding glaciers; 2. species
of plants and animals appearing in places where they have been
unknown; 3. rising sea levels; 4. severe heat waves)
Segment Six Topic: Confronting Environmental Threats: New Ideas
Our environmental challenges are considerable, but a growing awareness
of their seriousness is leading to new ideas in successfully addressing
them. Segment Six presents a few of these successes: innovative
soil management in Pennsylvania, plant breeding in Israel and Iowa,
and wind generators that can do the work of fossil fuels. It is
our hope that human ingenuity and commitment to meeting our environmental
problems will prove equal to the environmental problems that we
Finding Segment Six (Length: 6 Minutes)
and audio cues: Start when you see a field and barn in Pennsylvania
and hear “Five (Eight?) thousand miles away
are the gently rolling hills of southern Pennsylvania.” Stop
when you hear “Yet in the end,
there are no easy answers, no quick fixes.”
Post – viewing Discussion
- The film shows several innovative measures that people are implementing
to better manage our environment. What are they, and what problems
are they addressing? (Answer: 1. no-till farming that reduces soil
erosion; 2. plant breeding that will enable farmers to grow more
crops in difficult environments like deserts; 3. wind generators
that can reduce our dependence on fossils fuels, which contribute
to global warming)
- After viewing
the film, are you more or less worried about your future?
What worries you the most, if anything? What do you think
we need to do to ensure that you and the planet’s
environment have a healthy future?
What do you think we need to change?
Special Projects: The State of the Planet
Since many environmental problems facing the world today are occurring
in developing countries, it is important for students to try to
understand what living conditions are like in those countries.
This can be a challenge, because they are so different from ours.
Assign teams of 2-4 students and have them select a developing
country in Africa, Latin America, or Southeast Asia to research.
The World Resources Institute web site www.wri.org can
be helpful. Ask them to find out the following:
- The per capita income
- What the economy is based upon. The percentage of the economy
that is based upon agriculture, rather than industrial production
- The average life expectancy
- The literacy rate for both males and females
- The infant mortality rate
- Per capital energy use
- How energy is generated, e.g. firewood compared with fossil fuels
- How senior citizens are looked after
Putting all this together for themselves and others, the teams
can either compose a story about a typical family in the country
they have studied and read it to the class, or they can make posters
illustrating how people live.
Once your class is familiar with the lives of people in developing
countries, they can move on to the next activity:
What kinds of countries are undergoing the most
rapid population growth? You can find out by obtaining data from
the World Bank’s
web site www.worldbank.org/depweb/english/modules/social/pgr/.
Click on Maps at the top of the page. This should produce a map
revealing a map illustrating comparative population growth rates
around the world. Now consult either the World Bank web site or
the World Resources Institute web site to find out the following
of selected countries, see how population growth correlates with
- Birth and death rates
- Life expectancy
- Literacy rate
- Female/male enrollment in schools
- Population and population density
- Projected population growth in rural and urban areas
- Access to water and sanitation
- Immunization Rates
the results your students should see:
- Population growth rates are high when:
- Birth rates are high
- Death rates are high
- Life expectancy is low
- Literacy rates are low
- Relatively few females are attending school
- Access to water and sanitation is low
- Poverty is high
- Nutrition is low
- Immunization rates are low
Population density does not correlate with population growth rates.
Some densely populated countries, as in Europe, see very low population
growth rates. Others, as in Bangladesh, see relatively high population
Some of this data may seem counterintuitive. How is it possible
for countries with the highest death rates, lowest life expectancies,
most disease, and lowest levels of nutrition to have the highest
population growth? Trying to make sense of this can engage your
students in a stimulating and enlightening discussion. Ask your
students the following:
- If farming depends largely on human labor, rather than machines,
then how many children will you want? (Answer: A lot to help do
the work on the farm)
- If you have no pension or social security, who is going to take
care of you when you reach old age? How are you going to ensure
that someone will be around to take care of you? (Answer: You want
to have enough children to ensure your future.)
- If infant mortality is high, because many diseases are present,
how are you going to ensure that enough children survive for the
above two purposes? (Answer: Have a lot of children as an insurance
- If health services are minimal so birth control devices are hard
to obtain, what might happen? (Answer: A higher number of unplanned
- In some cultures in developing countries, males
consider it a status symbol to have a lot of children. Women, on
the other hand, are often solely responsible for taking care of
the children and often have little say in how many children they
are going to have. What might this combination of factors lead to?” (Answer:
- Taking all of these factors into account, what might people do
to reduce population growth in developing countries? (Some possible
answers: improve public health services to reduce infant mortality,
provide birth control devices, improve female literacy and empowerment,
increase industrial development, and mechanize farming techniques)
Have your class discuss how their well-being and sense of security
might be connected to the well-being of people in developing countries.
They might consider:
- Security. (Possible answers: Poverty and desperation can lead
to civil strife, violence and terrorism which can threaten the
United States. Illegal and uncontrolled immigration into the United
States can increase. Visitors to countries with many poor and desperate
people may be at risk through street crime and violence.)
- Financial well-being. (Possible answers: Chaos and violence hurts
national economies. People cannot find work, cannot buy products
imported from the United States, and may require increased financial
aid. The United States is often approached for help during times
of political and economic instability.)
- Environmental well-being. (Possible answers: In countries experiencing
poverty and upheaval, natural resources are often put at risk.
Forests are cut, wildlife is slaughtered, and natural habitats
are destroyed. The loss of biodiversity and destruction of natural
systems affect people worldwide in different ways.)
- Health. (Possible answers: Countries in chaos usually cannot provide
adequate medical care or sanitation for their citizens. Epidemics
can appear and spread, sometimes to United States shores. Visitors
to these countries many become sick there, as well.)
- Peace of Mind. (Possible answer: Observing scenes of poverty and
violence on the television or in magazines deeply disturb many
Having considered these issues, your students can now debate the
following: Should the United States increase foreign aid to developing
countries to help them combat poverty and environmental degradation?
Consider the following:
- The responsibility, if any, of people in the United States toward
countries less well off
- Whether money directed to foreign aid will help us in the United
States, or whether it should all be spent here instead
- What the relationships between the United States and developing
countries would be like if the United States reduced or eliminated
foreign aid. What would be the consequences?
What water issues are facing your community? Surprisingly, many
if not most people know little about where the water they drink
comes from, what is done to make it safe for human consumption,
and where it goes after people are through with it. Ask if a member
of the water department, the local environmental agency, or agricultural
service can come visit your classroom. Some questions to ask:
- Where does our water supply come from?
- What potential contaminants are being monitored? Are there any
that are not being looked for? Is the water department, for example,
monitoring prescription drugs or caffeine, which are now showing
up in water supplies?
- How is it treated to make it safe? Can we be sure that all potential
contaminants are being detected and removed?
- Have there been any instances when the water was found to be unsafe?
If so, what were the problems and what was done about them?
- Where does our waste water go to be treated?
- How is it treated? (Primary, secondary, or tertiary?)
- Does your community have combined sewers in which sewage from
homes and industries mixes with runoff from streets and sidewalks?
- Where does the water go after it is treated?
- Are the industries in your community required to pre-treat their
wastes before dumping them in the sewer system? Who monitors this
- Have there been any instances where waste water did not meet local,
state, or federal standards? If so, what were the problems and
what was done about them?
- How polluted are the waterways in the community? What are the
main pollutants? Where do they come from? How can the community
- Have rainfall patterns changed in the last decade or so? Is your
community receiving the same amount of precipitation as before?
- Is your community facing an impending water shortage? If so, what
is the cause (e.g. reduced rainfall, reduced runoff from upstream,
- If a water shortage or drought is occurring, what have been the
consequences? What does the future look like?
- Is it thought that any connection exists between the changed weather
patterns and global warming?
- What can people in the community do to reduce personal water use?
What can the school do?
- Where does runoff from the school end up? Obtain a topographic
map that includes the school and note the watershed in which the
school resides. Where the runoff goes will be downhill. Now take
the class on a walk around the school. Note the pollutants on the
grounds, e.g. oil, gasoline, and anti-freeze on the parking lots,
fertilizers and insecticides applied to the athletic fields and
gardens, dog waste, and litter. Locate the nearest storm drains
and visit the water body into which they are likely to empty. Finally,
discuss what the local environmental impact of the school is and
what the school might do to reduce it.
How does the caloric intake of your students compare with that
of people in developing countries? Divide your students into teams
and assign to each a particular region: Asia, Europe, Middle East
and North Africa, Sub-Saharan Africa, North America (A very easy
one, only two countries), Central America and the Caribbean, South
America, and Oceania. Now ask your students to consult the World
Resources Institute web site for information. The path to take:
1) Begin with the web site home page, www.wri.org.
2) Click on Earthtrends. 3) Click on About Earth Trends, then
Citing Earth Trends. 4) Click on Agriculture and Food. 5) Click
on Data Tables. The right hand column will be “Average Daily Per
Capita Calorie Supply (a,b) Kilocalories 1999”.
Each team should then scroll down to its particular region and:
- Record the average caloric intake for the region
- Rank the countries according to their individual caloric intake.
- Note the countries with the highest and the lowest caloric intake
Each team should then return to the Agriculture and Food page,
then 1) Click on Country Profiles; 2) Click on the countries with
the highest and lowest caloric intake in their regions, and 3)
Note the graph that describes the Index of Total and Per Capita
Food Production. Record for each country whether the Per Capita
Food Production is rising or falling.
Once everyone is finished, reconvene the class and summarize:
- Rank the regions according to their average per capita caloric
intake. Which region sees the highest? Which region sees the lowest?
- Rank the countries with the highest and lowest per capita caloric
- What 10 countries have the highest? In
which regions are they found?
- What 10 countries have the lowest? In which
regions are they found?
- Of the countries profiled, how many are witnessing rising or falling
per capita agricultural production?
- A minimum healthy caloric intake is estimated to be 2350 calories/day.
How many countries are below this figure? In which regions are
The debate continues to rage concerning whether
human activity is causing the planet’s temperature to rise,
and what, if anything, we should do about it. It is very difficult
for us to get accurate and current information about this issue,
since so much information seems to be coming from apparently biased
sources with agendas that are coloring what they tell us. Nonetheless,
it is important for us to try to decide for ourselves whether
global warming is occurring and whether the ramifications could
be serious. If we think it is happening, then we might feel compelled
to reconsider many of our day-to-day actions and decisions. Trying
to separate truth from conjecture or propaganda can be a useful
exercise for your students. They can apply the lessons that they
learn to other situations that they encounter when they are out
Ask your students to consult the internet and find out what people
and organizations are saying about global warming. They may work
in teams or individually. Ask them to record the following:
- Any straight facts or data, rather than opinion, that indicate
whether or not global warming is occurring
- Any opinions about whether it is occurring and whether or not
it is a bad thing
The organizations that claim global warming is serious and we
need to do something about it. Try to put these organizations into
categories, e.g. International, federal, state, or local governmental
entities, environmental organizations, fossil fuel industries,
political party organizations, and advocacy organizations with
distinct agendas such as free markets, small government, or reduced
Repeat this process for organizations that claim that global warming
is not serious.
Now ask your students to share what they have found.
- What do the facts suggest about global warming?
- What types of organizations are claiming it is human-caused, serious,
and needing to be addressed?
- What types of organizations are claiming that global warming does
not need to be addressed?
- What can you conclude about the organizations on each side of
this debate? Why do you think they have the views they do?
- Overall, which side seems more compelling to you and why?
Your students can now wrap up their research with a debate. They
can consider the question: What should the United States do about
global warming? Some options to consider:
- Impose a gasoline tax so people will drive less
- Tax people who drive SUVs and other vehicles that use a lot of
- Invest tax money in energy technology like solar power and wind
power that might replace burning coal and oil
- Invest tax money in building subways and bus lines
- Establishing more HOV (high-occupancy vehicle) lanes that are
restricted to people who are car-pooling
An effective way to structure a debate is to ask
the students to “fishbowl.” Set up four or five chairs in the room
so that they face each other. Three or four of these will be for
students who will initiate the debate; they will stay for roughly
5-10 minutes. One chair will be the “hot seat”.
This is for the rest of the class. If someone hears something
in the debate that he/she wants to respond to, he/she may sit
