1. Natural Resources
● Natural Resource: is
any useful material
found in the
environment.
– Soil
– Water
– Minerals
– Vegetation
● Anything that helps
meet people's needs..

2. Different types of resources
1. Recyclable Resource:
Resources that cycle naturally
throughout the environment. (water
cycle)
2. Renewable Resources: A
resource that can be replaced in a
timely manner. (corn, livestock)
3. Nonrenewable Resources When
they are used up, they cannot be
replaced in a timely manner.
(minerals, coal, natural gas,
petroleum/oil)

3. Fossil Fuels
● Fossil Fuels were
created over millions of
years from the remains
of prehistoric plants and
animals.
● These fuels are no
longer being created.
(nonrenewable)
● Examples: coal,
natural gas,
petroleum.

4. How people use the Land..
● People across the world use
their land and natural
resources in different ways.
● We categorize these
different ways into three
stages.
– First-Level Activities
– Second-Level Activities
– Third Level Activities

5. First-Level Activities
● At this level people
use land and
resources directly to
make products.
– Hunt, cut wood, mine, fish
● As the world
develops fewer and
fewer people are at
this level.

6. Second-Level Activities
● At this level people turn
raw materials into
things they use.
– Farmer takes his corn
crop to a mill and have it
turned in to corn meal.
● Raw materials are
manufactured into a
finished product.
Corn Mill

7. Third-Level Activities
● At the third level, goods
are no longer being
made, but rather a
service is being provided.
● More industrial nations
require service
industries.
● Service industry—
providing a service rather
than producing a good or
service.

8. Developing vs. Developed
Nations
● Developed Nations
– Lots of Industry
– ¼ of the world
– Use goods made in factories.
– Consume a great deal of raw
materials.
– Most live in towns/cities.
– Most have food & water
– Good healthcare & Education
– Commercial Farming
Problems: Unemployment,
environmental problems, shortage of
natural resources
● Developing Nations
– Little Industry
– Majority of the word's
population.
– Subsistence Farming
– Live off the land.
– Little wealth
– Many hunters-gathers.
Problems: disease, food shortages,
unsafe water, poor education and
health services, and changing
governments.

Environment
● Deforestation
● Global Warming
