Answer 2

30%

Question 3

give 6 reasons for the amazon being cut down:

Answer 3

• commercial logging
• subistence farming
• commercial farming
• mineral extraction
• energy development
• road building

Question 4

what is commercial farming?

Answer 4

• 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

Question 5

• small scale farmers = forest = to grow food for themsleves & their famlies

Question 6

whats commercial logging?

Answer 6

• amazon cut down = for valuable hardwood

Question 7

whats mineral extraction?

Answer 7

forest cleared to enable them to mine for valuable minerals e.g gold = to boost countries development can trade these resources

Question 9

whats energy development?

Answer 9

building hydroelectric dams flood the forest [can generate renewable energy]
- although there is a risk of flooding
e.g BALBINA DAM

Question 10

whats road building?

Answer 10

cleared forest to build 4000km TRANS-AMAZONIAN-HIGHWAY
& more roads into peru

• inc Q & T sector, trade improved = mutiplier effect

Question 11

name the 4
impacts of deforestation:

Answer 11

• climate change inc
• destroys habitats [ soil erosion] - reduced biodieversity
• economic

Question 12

explain the climate change impact

Answer 12

• trees reomove CO2 from the atmosphere [carbon sinks]
• Amazon stores 140 billion tonnes of carbon
• up to 75% of Brazils CO2 emissions come from deforestation
• machinary burns fossil fuels inc co2 emmiosons
• cattle/rice farming = relases methane

Question 13

explain the impact on soil erosion

Answer 13

• leeching = floods wash minerals out of soil = trees die = less inteception from trees
• may cause farmers to find new areas = more deforestation

Question 14

expalin the impacts on econmically

Answer 14

• farming especially & hardwood from logging
  = bought wealth
• mining industry = jop opps

Question 15

How is Brazil reducing deforestation?

Answer 15

• 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
