The rainforest
Causes of deforestation
-
Comercial farming
It is cattle ranching for beef and soy - soy is used to feed cattle in HICs. Brazil made £5.5 billion from trading cattle and is the largest exporter of beef in the world.
Logging
NOT FOR PAPER! For construction especially as rainforest trees are hardwood, perfect for building and furniture. The trees mainly used are mahogany and teet.
Road building
Trans Amazon highway, to open the rainforest fro development (getting big trucks in/out) Brazil needed a huge main road that runs the length of the Amazon 4000km (or Lands End to John O Groats 3 times)
Mining
It is open cast open blast mining. Minerals under the rainforest are valuable like iron, bauxite (aluminium) In Peru one mine alone employs 3000 people. These mining companies and employees pay taxes which are used to provide public services like hospitals and schools.
Energy development
Or HEP Hydro-electric power. 48 dams on the Amazon river already and further 150 planned to provide cheap and Carbon dioxide free electricity to businesses and people. It's the businesses that also need the cheap electricity
Settlement
For workers and their families from miners to loggers to farmers. New villages and towns are being created as land is deforested and land is being given to people to stop them from moving to the crowded cities like Rio.

-
The leaf litter falls to the ground and the decomposers then break down the leaf litter which provides nutrients for the soil which allows the plants to grow
