A
30%
3
Q
give 6 reasons for the amazon being cut down:
A
- commercial logging
- subistence farming
- commercial farming
- mineral extraction
- energy development
- road building
4
Q
what is commercial farming?
A
- forest cut down for cattle grazing or big plantations
- e.g there 200 million cattle = need more space
- also need more space for rice production etc
5
Q
whats subsistence farming?
A
- small scale farmers = forest = to grow food for themsleves & their famlies
6
Q
whats commercial logging?
A
- amazon cut down = for valuable hardwood
7
Q
whats mineral extraction?
A
forest cleared to enable them to mine for valuable minerals e.g gold = to boost countries development
8
Q
A
9
Q
whats energy development?
A
building hydroelectric dams flood the forest [can generate energy]
e.g BALBINA DAM
10
Q
whats road building?
A
cleared forest to build 4000km TRANS-AMAZONIAN-HIGHWAY
& more roads
11
Q
name the 3 impacts of deforestation:
A
- climate change inc
- soil erosion
- economic
12
Q
explain the climate change impact
A
- trees reomove CO2 from the atmosphere
- Amazon stores 140 billion tonnes of carbon
- up to 75% of Brazils CO2 emissions come from deforestation
13
Q
explain the impact on soil erosion
A
- leeching = floods wash minerals out of soil = less inteception from trees
- may cause farmers to find new areas = more deforestation
14
Q
expalin the impacts on econmically
A
- farming especially & hardwood from logging
= bought wealth - mining industry = jop opps
15
Q
How is Brazil reducing deforestation?
A
- Paris Agreement - brazil agreed to reduce there emissions by 37% by 2025
- global awareness = reduced demand for products from deforeted areas
- WWF funds = protect over 44% of Rainforest
- Brazil goverment use satelitte imagery to prevent illegal large scale logging
