Warm-up 9/8-9/9
1. What are 3 “commons” that you are impacting by your consumption, as measured in the ecological footprint activity?
2. For one, tell me what negative impact you are having, and changes you could make to move towards a more sustainable use of that common.
RED = vocab!

Learning Targets
I can calculate the approximate amount of carbon dioxide I produce in a given school year
I can make a diagram to show a thorough understanding of the principles of sustainability and earth’s resources

Ecological footprint Activity Review Have your team captain lead you through
each section of the ecological footprint activity, comparing answers and helping each other with calculations, etc.
I will answer whole group questions in a few minutes.
Team captain = person who traveled the farthest away for Labor Day weekend

Principles of Sustainability and Earth’s Resources
Chapter One Key Learning
![Page 6: APES 9/8-9/9 Please take out your lab book and ecological footprint activity](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f1c5503460f94c32dba/html5/thumbnails/6.jpg)
Principles of sustainability
How has earth sustained a huge, healthy diversity of life for so long? Principle one: dependence on solar energy
There is a constant, one-way flow of energy Principle two: genetic biodiversity and evolution
Life has evolved to use resources and adapt to change Principle three: cycling of water and nutrients
Molecules needed for life are available in many forms and recycle
The earth is a sustainable ecosystem with its own natural systems for maintaining balance.

Natural capital = value of the earth Natural capital, the earth’s value to
us, consists of natural resources and ecosystem services
Natural resources = matter and energy vital to human existence Renewable = regenerate if given
enough time (i.e, forests, topsoil, fishes, clean air, fresh water)
Inexhaustible = won’t run out in our lifetime (i.e. sunlight)
![Page 8: APES 9/8-9/9 Please take out your lab book and ecological footprint activity](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f1c5503460f94c32dba/html5/thumbnails/8.jpg)
More on natural Resources
Sustainable yield = highest rate at which we can use resource without reducing its supply
i.e. if only 1,000,000 new cod are born each year, only fishing that many
Tragedy of commons = overfishing, overharvesting, overgrazing, etc. of natural resources
Non-renewable/exhaustible resources = fixed quantity or regenerates very slowly
Natural gas, oil, metallic minerals (iron, copper, etc.), non metallic minerals (salt, sand, clay)

Ecosystem services
Processes provided by the earth
that make our lives possible: Cycling of important molecules Food production Climate control Water purification UV protection

Monitoring our impact Environmental scientists study environmental indicators to
measure our impact on natural capital
1. Biodiversity – (ecology unit II)
1. Ecosystem level – number and types of healthy habitats
2. Species diversity- number and types of individual species
a. Compare current extinction rate to background extinction rate
(what’s actually happening vs. what should happen over a long period of time)
3. Genetic diversity- number and types of genes in existence
![Page 11: APES 9/8-9/9 Please take out your lab book and ecological footprint activity](https://reader036.vdocuments.site/reader036/viewer/2022062422/56649f1c5503460f94c32dba/html5/thumbnails/11.jpg)
Environmental indicators, cont..
2. Food production (land use unit)- can we feed our exploding population?
3. Average global surface temps. And CO2 concentrations (air pollution unit)
4. Human population (this unit)
5. Resource depletion (land use unit)

Practice Time! Create a diagram of an ecosystem (forest, ocean, desert, grassland,
etc.) Depict (show) the following terms somewhere on your diagram. No definitions or explanation needed, unless it is not obvious.
Natural capital Natural resources Ecosystem services Renewable resource Non-exhaustible resource Non-renewable/exhaustible resource Sustainable yield
