U n i t i Introduction
the human population level on this planet has grown so rapidly in the
last century that there is cause for concern. We will probably number over
9 billion by the year 2100! Managing our natural resources in a sustainable
way to care for such vast numbers of people will be your challenge.

True or false? Water is a renewable resource because we can use it, treat it, and then use it again.
True or false? Forests are a good example of a nonexhaustible resource because they grow back after we use them.
Iron is an exhaustible resource. Does that mean we will run out of iron soon?
Is nature ever really "balanced"?
Which is more complex, a food chain or a food web?
What term is used to identify a "species that is non-native and that causes environmental or economic harm"?
What term is used to identify the maximum number of any given plant or animal that a given area can support?
The United Nations predicts that the world's human population will stabilize at around how many billions
over the next three centuries?
9. What management system uses a single resource (like a forest) for more than one use (such as wood production, hiking, hunting, and water control)?
10. If we use a natural resource carefully and in such a way that we should not "run out" of it in the foreseeable
.
future, we are practicing

Water and Air Resources

SuggESTED ACTIVITIES
1. Keep an account of all the water you use in one day. Look at the list and evaluate the areas where you might
have saved water.
2. Make a report of the major water-using industries in your area. Compare this to the water resources available.
Answer this question: "Is there a water shortage in my area?"
3. Do an Internet search for "video of hydrologic cycle" to find several short clips explaining the water cycle.
Both NASA and NOAA have interesting YouTube videos.
4. Here are some ideas for several research projects to examine rates of evaporation and sublimation in several
settings.
a. Weigh a chunk of ice and place it in an open container in a frost-free freezer. Weigh a similar quantity of
water and place it in an identical open container in an open room at the same time. Weigh the ice and
water a week later to compare the water-loss rates.
b. Compare evaporation rates between a wide-mouthed glass bowl and a glass bottle with a small opening.
c. Compare evaporation rates between identical containers of water, one sitting in the shade and one sitting
in direct sunlight, in the same room.
d. Add dark food coloring to one container of water and leave the another container of water clear. Then
place both containers in direct sunlight. Do the containers reach the same temperature? Do they evaporate
at different rates?
