Q

How can deforestation affect the carbon cycle in the Amazon?
3 ways

A

Nutrients washed away - loss of carbon
Less leaf litter - reduces absorption of carbon
More atmospheric CO2 caused due to fewer trees.

17
Q

How has climate change affected the Amazon?

A

Drought risks.
Extinction of species due to high temperature.
Wildfires

18
Q

What is selective logging? How does this limit human impacts?

A

Oldest trees cut down. Less damaging and keeps the forest structure.

19
Q

How does replanting trees help limit human impacts in the Amazon?

A

Variety of trees kept

20
Q

How can environmental laws help protect rainforests?

A

Ban use of wood that is not managed sustainability
Ban selective logging
Laws that control land use

21
