- forest floor
- 2% of sunlight. Very dark and damp. Prone to flooding.
Thin layer of decomposing leaves and dead animals-
called litter. This forms a layer of nutrients for the trees.

- uses
- rubber tapping
- 63,000 people earn a living supplying rubber to Brazil. it is
sustainable and the workers benefit because you cut out the
middle man

- mineral extraction
- gold, copper and diamonds can be found underneath the rainforest.
cyanide is used to extract the minerals. huge craters are left behind that are
filled with chemicals. stories of huge riches being made drive lots of people
into this industry.

- farming- palm oil
- 50% of packed products in supermarkets contain palm oil. they
burn the rainforest down then grow palm oil trees. this reduces
the bio divercity of the land and destroys lots of habitats

- slash and burn
- 1/3 of deforestation is caused this way. 2 acres of
land is destroyed every second, so within a 100 years
we may not have any tropical rainforests

- road building
- the trans-American highway is 2500 miles long. it goes from
Peru's Pacific coast to Brazil's Atlantic coast brings jobs and trade
but leaves destruction in its wake.

- selective logging
- more sustainable. less damage to
rainforest. using elephants no
machines.forest not neaded to be
cleared. machinery only used in
transport

- Parque Amazonia
- 19,000 acres along the guama river. 13,000 of the acres is rainforest. all developments
limited to 1,900 acres on open land that has already bean deforested in the 1800's. it is
20miles from Belem in Brazil, home to 1 million people. it offers big opportunities for
rainforest exploration and education. it opened its doors to the public in 1995.
