1. Environmental Problems, Causes and Sustainability
TODAY 8/31/16:
Environmental Problems (PPT) NB #7
An Introduction to Environmental Science

2. Notebook #7
Environmental Problems

3. Living Sustainably
Environment-everything that affects a living organism
Ecology-Study of relationships between living organisms and environment

4. Brainstorm with your learning partner and do the following:
List as many factors of the “environment” you can for Nemo on the left side of your interactive notebook (DRAW Nemo in the middle)
Now, distinguish between the living (biotic) and non-living (abiotic) factors

5. list as many environmental problems as you can in 2 minutes
Time the students and then have them share - compile as a list on the board

6. Major Environmental Themes
Resource depletion
Pollution
Extinction

7. Resource depletion Using up our natural resources
Forests, water, soil, minerals, wildlife, etc.

8. Renewable resources Continually replaced
Soil (but takes hundreds of years!)
Trees
Sunlight
Wind
Crops
Geothermal

9. Non renewable resources
Exhaustible
Fixed quantity
Renewed on scale of millions of years
Examples? Think- Pair- Share
Fossil fuels
Oil, gas, coal, uranium
Minerals
Salt, copper, aluminum, etc.

10. Causes for resource depletion…
Rapid population growth
Unsustainable resource use
Technology – good & bad
Not including the environmental costs in products
Trying to manage nature with too little knowledge

12. Pollution contamination of the environment
that causes instability, harm or discomfort to the ecologic systems or living organisms

13. Pollutants are often chemicals but can be solid materials or even energy, such as noise, heat, or light energy that contaminate our water, air or soil

14. Point Source
pollution comes from single, identifiable source

15. Nonpoint pollution Sources are dispersed and difficult to identify
Ex. Fertilizer on lawns, farms, golf courses

16. Pollution Solutions Prevention /input control 5 R’s Refuse Replace
Reduce
Reuse
Recycle

17. Extinction
The end of the existence of a species - the death of the last individual of a species
Amur Leopard – only about 40 left

18. Have students come up to read – there’s a lot of info on this infogrpahic

19. Reasons for extinction
List all that you think first….
Habitat destruction
Invasive species
Poaching
Black market
Let students discuss and list reasons before revealing reasons

20. So what’s at the root of these problems?
population

21. POPULATION CRISIS
Number of people is growing too quickly for earth to support
High population growth mostly in developing countries

23. Doubling time “Rule of 70” 70/ % growth rate=doubling time in years
At this rate when will population double?
How old will you be?
31.58

24. Let’s practice ! Use rule of 70
In 2012, the United States was growing at 1.9%
In 2012, Niger was growing at 7.1%
US 36.84
Niger 9.85

25. Compare Developed and Developing Countries
Give students time to think and share out

26. Developed Countries Highly industrialized high per capita GNP
Slower growth
Can you think of a few?

27. Developing Countries Low to moderate industrialization
Low to moderate per capita GNP
Fast growing
What are some other indicators?
Hmmmm....

30. Example
Poor parents in a developing country would need children to have the same resource consumption as 2 children in the U.S.!!!! WW!!!!

32. CONSUMPTION CRISIS
Using, wasting or polluting natural resources faster than they can be renewed
Mostly occurring in developed countries

33. Sustainability Ability to survive and function for a specified time
Sustainable Earth – Is it possible?
Ask why the picture of the deer?

34. Sustainable Society manages society, economy and population
all resources managed to last indefinitely
EARTH all resources managed to last indefinitely

35. Sustainable World Considerations
