Answer 6

cattle ranching , roads, logging

Question 7

negatives/consequences of cattle ranching

the stats!!

Answer 7

• destroys animal’s homes and plants
• 60% of deforestation is caused
• 1/5 of greenhouse gases are emitted

Question 8

negatives/consequences of logging

Answer 8

• causes illegal activity/government laws ignored
• machines compact the soil and so heavy rain washes away soil
• soil looses fertility
• tribe members could be killed

Question 9

what is logging?

Answer 9

chopping down trees and collecting wood to sell

Question 10

negatives/consequences of roads

Answer 10

• increases crime rates in towns
• prices for items in towns increase so it’s less affordable for the people living there
• cuts through mountains eg the Andes

Question 11

positives of cattle ranching

Answer 11

• exports beef all over the world

- helps economy, brings in money etc

Question 12

positives of logging

• removes leafy trees so smaller ones can get sun
• gives jobs and money

Question 13

Question 14

what is shifting cultivation? Who uses it? why is it sustainable?

Answer 14

• slash and burn trees and vegetation (this gives nutrients to the soil) and then they grow and harvest crops. when the soil starts to lose its goodness they move on to another part of the rainforest to leave that land recover.
• the kayopo tribe
• it is not completely destroying rainforest and leaves land to grow

Question 15

ways to make deforestation sustainable and their categories

Answer 15

• afforestation (replanting trees as they are cut down - use ecosia example)
• nature reserves (limited and controlled deforestation)
• heli-logging (using helicopters to only remove the trees that we need rather than damaging the surrounding trees)

categories =

• afforestation = global
• nature reserves = national
• heli-logging - national

Question 16

why are these solutions sustainable?

Answer 16

afforestation = we can continue doing this for a long time and keep the number of trees balanced and hopefully increase their numbers

nature reserves = not as sustainable because deforestation is still occurring but just not as quickly, however it does give us time to figure out long term solutions.

heli-logging = sort of same as nature reserves
