6 causes of deforestation in the Amazon Rainforest
- farming
- logging
- road building

- energy
- population growth
Deforestation: Farming - what is farmed?
-cattle ranching accounts for 80% of deforestation
-soybeans, palm oil
Deforestation: Logging - what woods are logged?
-teak
-mahogany
Deforestation: Road building - one example
Trans-Amazonian highway
Deforestation: Mineral Extraction - 2 examples + specific mine
-copper, gold
-Carajas (iron ore mine)
Deforestation: Energy - HEP station example
Belo Monte Dam
4 social opportunities of rainforests
-medicines (25% from rainforests)
-energy (HEP)
-resources (bananas, sugar)
-employment
3 environmental opportunities of rainforests
-water (20% earth’s freshwater)
-biodiversity (50% world’s plants and animals)
-climate (trees C sinks)
5 ways to sustainably manage rainforests
- international agreements
- debt reduction
- ecotourism
- selective logging and replanting
- conservation and education
Sustainable Management: One international agreement example

- inaccessible
WD challenges: How do houses manage extreme temps of 50C?
thick earth walls, white washed walls
WD challenges: Why is there a high water demand and how do they transfer water?
near Phoenix (golf courses, farms, homes) - transfer from Colorado river
WD challenges: 2 new roads build to combat inaccessibility
