Renewable, flow, and non- renewable

2. Natural resources
Natural resources are things found in nature that people find useful or valuable
Our natural resource use changes over time because:
we have greater access to food, building supplies, and fuel
Countries have expanded the idea of what “need” is
Technology has allowed us to improve the way we extract resources
Three approaches to addressing natural resource use:
Conservation
Preservation
Frontier

3. Habitats
Many species become extinct because we are destroying habitats in order to extract resources
We have focused more on economic benefit (making money$$$) than on environmental impact

4. Renewable resources
A renewable resource is a resource that can regrow or reproduce as long as it is not overused
We use renewable resources to meet our wants and needs for food, medicine, shelter, and material things such as clothes and furniture.

5. soil
Soil is an extremely important renewable resource. Without soil, we would not be able to farm, have livestock, or grow trees. All life on this earth would be affected.
Soil degradation is loss of soil quality or ability to grow plants. It happens because farmers overuse it and do not give it time to restore nutrients between planting and harvesting seasons.

6. fish
Fish populations reproduce themselves and are considered a renewable resource.
Fish are a valuable source of food for more than 1 billion people
Fish are also used as a source of food for pets and livestock
The demand for fish is increasing around the world as people in many developed countries have begun to replace red meats with fish in their diets.
Fish Stock: a group of fish of the same species that live in the same area
MSC: Marine Stewardship Council

7. forests
Forests are considered a renewable resource because they can regrow
a fully grown tree can be chopped down, used for firewood, processed for lumber, or manufactured into material goods.
Forests are important to local ecosystems
Trees store water that can be released into the atmosphere, keeping moisture in the air, which is an important part of the water cycle.
The roots of trees hold the soil together, stopping erosion, so more trees and other plant life can grow.
Trees absorb carbon dioxide, a major greenhouse gas
Trees provide oxygen, which all life needs to breathe

8. Soil health
Soil health is affected by deforestation because the roots of trees can protect soil from wind and water erosion

9. Types of flow resources:
Flow resource a resource that must be used up when and where it is found or it is lost
Types of flow resources:
Water
Sunlight
Air
Flow resources also supply us with energy when they are “on the move.” For example, we use the energy created by water when it flows as rivers, ocean currents, and tides.

10. A basic need for all living things
water
A basic need for all living things
The term water footprint describes the amount of fresh water used by individuals, communities, or businesses. It is useful to compare the water footprints of different countries.

11. air Air is a basic need. Every living thing needs it to survive.
Air pollution is dangerous because all living things breathe it.
“Animals breathe in oxygen and breathe out carbon dioxide (CO2). Plants use nitrogen and CO2 to produce their own food. Even microscopic bacteria use gases found in the atmosphere to survive”

12. the atmosphere
The gases in the atmosphere help to protect Earth. Without the atmosphere, it would get so cold at night that we would freeze. The heat and light from the Sun would be so intense it would burn us. Also, ultraviolet rays from the Sun can harm trees, plants, and animals.
Troposphere: the layer of the atmosphere closest to the earth
Weather takes place in this layer and so does most life on earth
Stratosphere: the second layer of the atmosphere which has a layer of ozone gas
Ozone layer: a region of ozone gases high in the atmosphere that protects us from ultraviolet light

13. sun
We need the sun.
The Sun provides us with heat and energy. Without the Sun, nothing could live on Earth. It supplies light and heat, both of which can be transformed into energy.
Plants use the Sun’s energy to make their food
Plants also produce oxygen
Most animals need oxygen, so they depend on plants
Solar power has little impact on the environment but needs lots of sunlight and space so it is not always a feasible (realistic/doable) option

14. Non Renewable
Non-renewable resources are natural resources that take millions of years to form.
Non Renewable resources cannot be replaced once they are used up and the world’s growing population is heavily dependent on them
Two Types::
Fossil fuels
Fossil fuels were formed from ancient plant and animal life.
Oil, natural gas, and coal are fossil fuels. Extracting these resources can be difficult
Minerals
Minerals are natural solid substances not formed from plant or animal life.
They are found in the rocks that make up Earth.

15. Fossil fuels
Fossil fuels are used to produce most of the world’s energy.
Oil and natural gas are refined into other substances. These substances are used to manufacture products, such as plastics, paints, rubber, and cosmetics.
Coal is the most abundant fossil fuel in the world

16. minerals Two types: Metallic Non-metallic
Where is it found? usually found in rocks that were molten (made liquid by intense natural heat, such as in volcanoes) and have cooled
Examples: aluminum, copper, gold, iron, nickel, zinc
Non-metallic
usually found in sedimentary rocks (rocks formed from sediment, which is matter carried by water or wind and deposited on the surface of the land
Examples: asbestos, gravel, potash, salt

17. Protecting the environment
There is no way to completely avoid environmental damage when extracting fossil fuels or minerals
Greener technologies can reduce impact by:
reducing energy consumption
reducing harmful chemicals used in processing
reducing water pollution by reusing water
reducing air pollution
