Clearing away trees so people can build ranches and farms.
Using resources in ways that do not harm the environment.
Producing and selling goods without making any profit.
Encouraging trade between native Amazonians and farmers.
Rainforests are nicknamed "the lungs of the Earth" because their rich plant life:
Plays a major role in the carbon-oxygen cycle.
Releases carbon dioxide, which we turn into oxygen.
Has organs that allow them to breathe like humans.
Homes tropical birds that help create carbon dioxide.
How is the native Amazonian's lifestyle a sustainable way of life?
Their lifestyle does not cause long-term damage to the rainforest.
They farm on very small areas of land for many years at a time.
They have lived on the same land for at least 12,000 years.
They fertilize the soil they use, and replant new seeds every year.
Which of the following is a way in which the native Amazonian people have been hurt by newcomers?
They have been driven off of their land by newcomers.
They have been killed by diseases newcomers brought.
They have been killed and injured in land use conflicts.

Why is rubber tapping considered a sustainable activity?
Rubber tapping naturally fertilizes the trees' surrounding soil.
Rubber tapping reduces the amount of carbon dioxide in the air.
Rubber tapping does not harm the tree that is tapped for sap.
Rubber tapping creates products that can be used for many things.
In the 1960s, land use conflicts arose between newcomers and rubber tappers when the government:
Encouraged deforestation so that farmers and ranchers could use the land.
Began charging rubber tappers higher taxes than ranchers and farmers.
Limited the number of trees a rubber tapper could use to collect sap from.
Made all rubber tappers work in groups to reduce how much land was used.
Why does logging harm the Amazon rainforest?
Loggers are required to live in the rainforest, so they build houses and buildings.
Loggers often litter the rainforest because there is no garbage system in the area.
Logging pollutes the air because trees release carbon dioxide when they are cut.
Loggers often clear-cut whole patches of rainforest, which leads to deforestation.
Loggers often argue that a benefit of logging in the Amazon rainforest is that it:
Creates new land for luxuries such as shopping malls and movie theaters.
Improves Brazil's economy by increasing the number of jobs in the forest industry.
Allows more people to live in the land by clearing away the dense forest.
Reduces the amount of time and effort needed to maintain the Amazon land.
Why did many poor families in Brazil settle in the Amazon rainforest?
The Brazilian government moved them there, and supplied them with food and money.
They formed small communities together to escape the poverty in certain cities there.
They settled among the native Amazon people, but established their own communities.
They were forced out of the cities in Brazil by the corrupt and wealthy business owners.
Why is the Amazon a difficult place for settlers to farm in?
There is too much rainfall.
The land is overpopulated.
The area is very hot and dry.
The soil is poor in nutrients.
In the rainforest, many cattle graze throughout the Amazon:
River.
Canyon.
Basin.
Lake.
Many ranchers argue that a benefit of raising cattle in the Amazon is that it:
Makes good use of the rainforest land by raising food and earning income for Brazil.
Increases the natural elements of the rainforest because cattle are native animals to Brazil.
Helps feed poor families in Brazil by creating affordable beef products for them to eat.
Makes the soil in the rainforest more fertile by having the cattle graze on the grassland.
