timber for furniture
paper from wood
land for crops then ethanol from crops for biofuels
grazing cattle for the food industry

Question 2

loss of biodiversity

Answer 2

could lead to the extinction of species which could have future uses, medicine, clothes, food

Question 3

what is biodiversity

Answer 3

the variety of animals and plants in a habitat

Question 4

releasing carbon dioxide and burning trees (3)

Answer 4

1 when trees are burnt, locked up co2 released
2decomposition (respiration) by microorganisms ( feeding on dead wood, release co2 as a waste product of the respiration
3 burning trees reduces the co2 taken in by photosynthesis by trees and trapped in wood… leading to climate change

Question 5

How is the conc of methane increased by deforestation?

Answer 5

land is cleared for grazing cattle and rice fields

both release methane which is a greenhouse gas

Question 6

What are peat bogs?

Answer 6

areas of ACIDIC and WATERLOGGED land

Question 7

How is peat formed?

Answer 7

plants living in peat bogs don’t fully decay because there isn’t enough oxygen
partly rotted plants build up to form peat

Question 8

how does carbon build up in plants in peat bogs?

Answer 8

carbon in plants is stored as peat instead of being released

Question 9

How does the stripping of peat bogs increase co2 release?

Answer 9

used as compost for gardeners

locked up co2 is released
