Objective: Understand How Human Population Is Related to Natural ResourcesKey Words: Natural resources, renewable, non-renewable, depletion, finite

Do Now:•List 3 things you have learned about human population growth

•The ultimate cause of all the environmental problems is _____________________•Human population growth shows a(n) ______________________________ growth.•Limiting factors for human population growth are ___________________________•Three factors that contributed to the human population growth are ________________________________________________________________________________

1. Describe the graphs. What do those graphs above show?

Human Population Growth

First graph shows how fish catch increased in the World from 1950 to 2000Second graph shows how human population increased in the last 1000 years

Objective: Understand How Human Population is related to Natural ResourcesKey Words: Natural resources, renewable, non-renewable, depletion, finite

Human Population Growth and Natural Resources

2. Compare / Contrast: What do they have in common?

3. What conclusion can you draw based on those graphs

Human Population Growth

World fish catch and human population growth increased over time.Fish catch increased steadily, meanwhile human population grew exponentially

As human population grew, the food demand increased, so fish catch increased too.


Human Population Growth and Natural Resources


Renewable and Non-Renewable Resources

Materials from the earth that are needed to sustain life or are critical for economical systems.

Examples: land, water, air, minerals such as copper, iron and gold

Natural resources that can be replaced by natural cycles

Fossil fuel, such as gas, coal and oil; or minerals, gold, iron, copper,…

Water, air, and trees.

Natural resources that cannot be replaced

1. Define natural resources.

2. Give some examples

3. Define renewable resources.

4. Give examples

5. What are nonrenewable resources?

6. Give examples



I disagree, because it takes time to replace them. Sometimes we use them faster than the ecosystem can replace them.

9. Do you agree or disagree with the following statement: “Renewable resources can be replaced, therefore their supply is unlimited” Justify your answer.

Science that deals in the management and use of natural resources.

Recycling, reforestation, and restriction on hunting and fishing

7. Define “Conservation”

8. List three common conservation practices.



As human population increases, it needs more natural resources increases, so natural resources decrease.

10. How is human population growth related to natural resources?

RenewableResources

Non-RenewableResources

Natural resources that can be replaced by natural cycles

Gas, coal and oil; or minerals, gold, iron

Water, air, and trees.

Natural resources that cannot be replaced



Regents Questions1. The reason that organisms can not produce populations of unlimited size is that

A) interactions between organisms are unchangingB) there is no carrying capacity on EarthC) species rarely compete with one anotherD) the resources of Earth are finite

2. One reason why people should be aware of the impact of their actions on the environment is thatA) ecosystems are never able to recover once they have been adversely affectedB) there is a decreased need for substances produced by natural processesC) the depletion of finite resources cannot be reversedD) there is a decreased need for new technology

3. The graphs below show the size of the human population in relation to food production per acre in four different countries over the same time period.

Which country survived the longest without the need for food imports?A) A B) B C) C D) D





Regents Questions4. What will most likely happen if the human population continues to grow at current rates?

A) There will be fewer natural resources available for future generations.B) There will be an increase in nitrogen levels in the atmosphere.C) There will be a decrease in water pollution.D) There will be an increase in the number of strong hurricanes.

5. Increased production of goods makes our lives more comfortable, but causes an increase in the demand for energy and other resources. One negative impact of this situation on ecosystems is an increase in

A) renewable resourcesB) pollution levels in the atmosphereC) living space for wildlifeD) the diversity of plant species

6. Describe the impact that the loss of nonrenewable resources would have on the environment.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

EARTH’S RESOURCES

Earth has a finite supply of resources. Two kinds.

a) Non renewable resourcesoCannot be replaced oEx: fossil fuel, mineral, gas, coal, oil.

b) Renewable resourcesoCan be replaceoEx: water, soil, air, wildlife.oThe must be used carefully.
