How do humans use natural resources?
Natural Resources
Oil-gasoline/heatForest- heating/cooking/buildingSoilFish & wildlifeMetals & mineralsRecreational resources
Nonexhaustible Resources
Resources that can last forever regardless of human activity
Human misuse can damageSurface water
Renewable Resources
Resources that reproduce themselves or can be reproduced by humans
Does not mean it will not be used up
Forest
Exhaustible Resources
Resources that cannot be replaced or reproduced
Once gone, gone foreverOilCoalSoil
Activity
Make a chart to compare/contrast inexhaustible with exhaustible resources, give 5 examples of each
10 minutes
Interdependent Relationships
The dependency of one thing to others
1- human/animal & plants, plants dependent to humans- supply plants sufficient carbon dioxide
Interdependent Relationships
2- human/animal & plants- humans dependent on plants- plants give us food, vegetables, & medicines
Other examples??
Communities in NatureForests, roads, meadows,
swamps, bee hives, towns, cities, etc
When 2 different communities meet & blend, this forms an ecotone
EX- forest meets low-growing plants
Communities in NatureIdentify communities assigned &
explain their specific interaction.15 minutesOutside observation- observe an
ecotone- explain in detail what you saw.

What affects population ecology?Lack of resourcesPrey to another speciesNatural disasters
Population Ecology
Carrying capacity- maximum population an area can hold/supply
Density dependent- as reach carrying capacity, overcrowding = less resources & results in decreased birth rate
Population Ecology
Density independent- some populations grow exponentially with no end

Top Environmental Issue
OverpopulationFrom list- which are direct or
indirect result of overpopulation?
Sustainability
“the simple principle of taking from the earth only what it can provide indefinately, thus leaving future generations no less than we have access to ourselves.” – Friends of the Earth
Sustainability
Involves living within limits of resources, understanding connections among economy, society and environment, and equitable distribution of resources and opportunities

Lesson Essential Question
What is found in an ecosystem?
Ecosystem Diversity
Consists of biotic (living) & abiotic (nonliving) subsystems
Biotic subsystem- relationship among plant & animal members of a food web
Ecosystem Diversity
Abiotic subsystem- water of a lake & the chemicals that dissolve from the atmosphere & land that affect the waters acidity level
Ecosystem Diversity
Everything on earth is part of one or more ecosystems
Choose ecosystem-make list of biotic species found in that specific ecosystem

Why do we recycle?
Lesson Essential Question
Why is recycling important?
Impact of Recycling
We do not recycle to save trees
Why is recycling important?
Impact of Recycling
Cost of solid waste disposalRecycling saves energy,
creates jobs, & generates revenue for us
Impact of Recycling
56,000 recycling centers employ 1.1 million Americans & generate $37 billion in payroll, Gross $236 billion in revenue
Energy needed to recycle aluminum can only 5% as much then from raw ore
Impact of Recycling
Nonrenewable resources important to reuse as much as possible as they will not always be available

Lesson Essential Question
Why are conservation & preservation important?
Conservation
Conservationists believe in using nature to produce the maximum long-range benefit for people
Conservation does not set aside resources simply to have them
Conservation
Oriented toward practical use for today & for the future
Bring to mind sentimental thoughts of nature & beauty, but true test for conservation is whether society benefits from its undertakings
Preservation
Some things worth having & guarding just for their own sakeLiberty Bell, Grand Canyon,
American Bald Eagle
Preservation
Heirlooms of our heritage should be preserved, because we, as people, value them. No other reason needed.
National Park ServiceMust balance desire for
preservation w/needs as people
Preservation
Questions to ask when trying to preserve a natural area: Can we use such resources
without destroying them, as we can with forests?
Can we afford to set aside such resources?
Preservation
Questions to ask when trying to preserve a natural area: Which is more important,
economic growth or the preservation of nature?
