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.

maximum population for earth?

Population Ecology

The study of populations & how they change over time

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?

To calculate wildlife population

Very hard to calculate exact # of populations

Wildlife managers take estimates 4 times a year- during breeding, after young born, before hunting/trapping, and after hunting/trapping season
