3. Humans and Sustainability
Environmental Problems, Their Causes and Sustainability

4. Bell Ringer: Silent, independent work
Which of the following would lower the carrying capacity of the hare population?
an increase of food
a decrease of lynx
an increase of lynx
a decrease of environmental disturbances
2. Explain why you chose your answer in #1
add a biodiversity review question to connect back to Ecology day 1

5. Think About It Over an average lifetime, each American will…
Through technology, humans now have the power to change the local and global systems on which all living things depend.
What effect are humans having on the global climate?
What can you do to reduce your environmental impact?
Over an average lifetime, each American will…
burn 31,350 gallons of gasoline.
read 5,054 newspapers equaling 43 trees.
discard 64 tons of garbage
use 1.8 million gallons of water
To the Teacher;
Determine your students’ prior knowledge by asking them to list different kinds of pollution. Ask them to provide examples of pollution in their local community and areas they have visited. Accept all reasonable answers.
Ask them to rate their examples from the most to least critical
Have students discuss examples of how an individual can contribute to solving an environmental problem. Accept all reasonable answers.

6. What are we learning today?
Objectives
Benchmarks
Predict how the actions of humans may impact environmental systems and/or affect sustainability
Evaluate possible environmental impacts resulting from the use of renewable and/or nonrenewable resources
SC.912.L Predict the impact of individuals on environmental systems and examine how human lifestyles affect sustainability. AA
SC.912.L Evaluate the costs and benefits of renewable and nonrenewable resources, such as water, energy, fossil fuels, wildlife, and forests.

8. What are some causes of environmental problems?
Rapid population growth
Unsustainable resource use
Poverty
Not including the environmental costs of economic goods and services in their market prices
Trying to manage and simplify nature with too little knowledge about how it works
To the Teacher:

9. Where do pollutants come from and what are their effect?
Pollutants are chemicals that cause harm to people or other organisms.
Natural (volcanic eruptions)
Anthropogenic (burning fossil fuels)
Pollutant have three types of unwanted effects
Disrupt or degrade life-support systems
Damage wildlife, human health, and property
Nuisance
Pollution does not respect boundaries.
Point sources of pollution are single, identifiable sources.
Nonpoint sources of pollution are dispersed and difficult to identify.

10. What are the key environmental problems?
Major Environmental Problems
Air Pollution
Biodiversity Depletion
Water Pollution
Waste Production
Food Supply Problems

11. What is the essential question?
How do you feel when you read that…
the average American consumes about 35 times more resources than the average Indian citizen
human activities lead to the premature extinction of at least 10 species per day
Do you feel skeptical, indifferent, sad, helpless , guilty, concerned, outrage, hopeless, or not want to think about it?
Which of these feelings help perpetuate such problems, and which can alleviate them? Explain your answer.

12. Air Pollution Global climate change Stratospheric ozone depletion
Urban air pollution
Acid deposition
Outdoor and indoor pollutants
Noise

13. Biodiversity Depletion
Caused by….Habitat destruction
42% of the planet's entire terrestrial net primary productivity
50% of all freshwater
Caused by..Habitat degradation
Causes… Species Extinction
Extinction rate is up to 30,000 species per year. That's three per hour!!!
Teacher should ask a biodiversity recall question -

14. Water Pollution Sediment Nutrient overload Toxic chemicals
Pick 3 examples to write:
Sediment
Nutrient overload
Toxic chemicals
Infectious agents
Oxygen depletion
Pesticides
Oil spills
Excess heat

15. Waste Production Write these examples: Solid waste Hazardous waste
Landfills

16. Food Supply Problems Pick 3 examples to write: Overgrazing
Wetland loss and degradation
Overfishing
Coastal pollution
Soil erosion
Soil salinization
Water shortages
Groundwater depletion
Poor nutrition
