2. OBJECTIVES

3. The Destruction of Earth’s Systems
What is human activity?
Actions that people do that might have a negative consequence
Source of food supply
An energy source
Source of recreation and constructions
Major source of medicines
Natural resources for industrial products
Earth’s system can provide us humans with Desires/ Solutions
Destruction of the “pure” system

5. Biosphere - Atmosphere
NATURAL: Biosphere releases carbon into the atmosphere through the biomass; therefore there is a small quantity of CO2 in the air
HUMANS: Interrupting this pure relationships by releasing more carbon dioxide into the atmosphere
Deforestation (eliminating carbonsinks)(construction)
Burning fossil fuels
Burn forests
Certain agricultural practices
Waste management
CAUSES: Global warming, change in the ecosystems, and acidification of the ocean

7. Atmosphere - Cryosphere
NATURAL: The atmosphere provides the perfect conditions for the cryosphere to exist
HUMANS: Releasing a lot of carbon dioxide/ greenhouse gasses(methane, nitrous oxide, etc.)
2/3rds of the current rates- glacial melting is due to human activity
25% to 2010
65% to 2010
Aerosols
CFC’s (coolants)
Eating meat
Production of cattle
CAUSES:
Global warming (greater impact)
Ocean Circulations are disrupted
Sea levels rise
Less habitat for the animals in the poles

8. Cryosphere - Hydrosphere (minor)
CAUSES:
Change in temperature
More water in ocean
Greater storms (force)
Sea levels rise
Over population (central regions)
Floods (coastal regions)

9. Hydrosphere - Biosphere
NATURAL: Provides a habitat for many animals/ plants
Crucial sphere- benefits to humans and animals
HUMANS: Wastes
Grand quantity of litter
Excess of carbon
CAUSES:
Fish intoxicated
Human health
Resource of food
Decrease in result of animals/ plants
Ocean becomes acidic

10. Geosphere - Biosphere
NATURAL: Geosphere provides pure soil when it comes to the formation of the biosphere
HUMANS:
Mining Extraction
Ore Extraction
Chemicals
Intoxication (pesticides/ fertilizers)
CAUSES:
Polluting our ecosystems
Natural Vegetation will be scarce
Biomass won’t develop properly
Loss in species

11. Conclution https://www.youtube.com/watch?v=WfGMYdalCIU
Earth’s systems are vital
Many ways humans can decrease the harmful activites
Consciousness
Being informed (consequences)

12. QUIZ TIME!
What were the five important relationships of shperes that I talked about?

13. Answer #1 Biosphere- Geosphere Biosphere - Hydrosphere
Hysrosphere - Crynosphere
Atmosphere - Crynosphere
Biosphere - Atmosphere

14. Q #2
What are some human activities that are destroying the relationship between the geosphere and the biosphere? (Be specific)

15. Answer #2 Mining extraction Chemicals Pesticides and Fertilizers
Ore extraction
Chemicals
Pesticides and Fertilizers

16. Q #3
What are the causes of human activity interfering with the relationship between the crynosphere and the hydrosphere?

17. Answer #3 Change in temperature More water in ocean
Greater storms (force)
Sea levels rise
Over population (central regions)
Floods (coastal regions)

18. Reflection Out-loud
Everyone has to come up with something they’ll do or stop doing to help decrease the impact on the relationship between spheres.
Explain which sphere you chose and what will you do.
