Chapter 22Humans & the Environment

22-1: An Interconnected Planet

Earth’s 3 Major Layers1. Geosphere

2. Hydrosphere

3. Atmosphere

Biosphere 2 (AZ)...didn’t work!• Not that simple!

Biodiversity• Species diversity:

• Genetic diversity:

Biodiversity-what we know so far...

Biodiversity-who cares?• Food• Habitat• Medicines• Chemicals• Photosynthesis/production/removing CO2• “Biological diversity is the key to the maintenance of

the world as we know it” –E.O. Wilson

Think About It!• How are these concepts related?– Human Activity– Ozone layer– Greenhouse effect– Global warming

Pollution #3: Acid Precipitation• What is it?

• What causes it?

• Why’s it bad?

Pollution#4: Biological Magnification• What is it?

• What causes it?

• Why’s it bad?

So, what’s the big deal??

Oil Spill Activity• Pre-lab ?s• Notes for each overlay• Questions for your group’s viewpoint• Debate • Who gets the $50,000?!

ECOSYSTEM DISRUPTION• All this happening...– High rates of end/ext...”mass extinction”

• Endangered species

• Extinction

• Habitat destruction, hunting, harvesting, invasive species

• https://www.dnr.sc.gov/pls/heritage/county_species.list?pcounty=charleston• ~100 rare, threatened, endangered in SOUTH CAROLINA!

Ecosystem Imbalances• Keystone Species

World Population Growth Models

Human Resource Use• Too much? Just right? Too little?

• Ecological Footprint

Human Resource Use

• Solutions?

• Sustainable Use

• Restoration Biology

Jwaneng mine (Botswana)Lab-grown diamonds vs. strip mining

Just ONE Example…

Google timelapse!• And in Charleston:• http://earthengine.google.org/#intro/AralSea
