What is the main threat to the rainforest in Brazil?

While the Amazon Rainforest remains the largest tropical rainforest in the world, deforestation from human activities threatens the continued existence of this astounding natural resource. An estimated 5.4 million acres of tropical rainforest is being lost within Brazil each year².

How does expansion of large cities affect the rainforest?

Population Growth Fuels Deforestation in the Amazon

Some researchers have argued that in addition to allowing migrants to raise their living standards, migration to cities in tropical countries might actually reduce forest loss by depopulating certain rural areas, allowing tropical forests to regrow.

What are threats to the Amazon rainforest?

About the Amazon

This vast untamed wilderness is under increasing threat from huge-scale farming and ranching, infrastructure and urban development, unsustainable logging, mining and climate change.

Who is destroying the Amazon rainforest?

Cattle ranching is the leading cause of deforestation in the Amazon rainforest. In Brazil, this has been the case since at least the 1970s: government figures attributed 38 percent of deforestation from 1966-1975 to large-scale cattle ranching. Today the figure in Brazil is closer to 70 percent.

What is killing the Amazon rainforest?

The cattle sector of the Brazilian Amazon, incentivized by the international beef and leather trades, has been responsible for about 80% of all deforestation in the region, or about 14% of the world's total annual deforestation, making it the world's largest single driver of deforestation.

Why is the tropical rainforest important?

As well as the vivid beauty that comes with great diversity in plants and animals, rainforests also play a practical role in keeping our planet healthy. By absorbing carbon dioxide and releasing the oxygen that we depend on for our survival. The absorption of this CO2 also helps to stabilize the Earth's climate.

What are the effects of deforestation in Brazil?

The impacts of deforestation include loss of biodiversity, reduced water cycling (and rainfall), and contributions to global warming. Strategies to slow deforestation include repression through licensing procedures, monitoring, and fines.

How might the loss of rainforest habitats affect the global environment?

Cutting the rainforests changes the reflectivity of the earth's surface, which affects global weather by altering wind and ocean current patterns, and changes rainfall distribution. If the forests continue to be destroyed, global weather patterns may become more unstable and extreme.

How does infrastructure expansion affect deforestation?

Some infrastructure activities, such as road building, have a large indirect effect through opening up forests to settlers and agriculture. Poor forest management and unsustainable fuelwood collection degrade forests and often instigate a "death by a thousand cuts" form of deforestation.

What is the role of urbanization and climate change in disappearing forests?

Urban and residential area expansion cause significant forest loss, both in the consumption of building materials and as a source of land. Rural abandonment can also spur outright conversion of forest by industrial farmers and ranchers, especially in areas suitable for large-scale agriculture. ...

How does urbanization increase deforestation?

Urban growth drives deforestation in at least two ways. First, as rural migrants to cities adopt city-based lifestyles, they tend to use more resources. Their incomes rise and their diets shift to a greater share of animal products and processed foods.

Why is the Amazon rainforest important to the world?

The Amazon rainforest plays an important part in regulating the world's oxygen and carbon cycles. It produces roughly six percent of the world's oxygen and has long been thought to act as a carbon sink, meaning it readily absorbs large amounts of carbon dioxide from the atmosphere.

Is the Amazon in danger?

The Amazon is still the most extensive rainforest on earth, but a disastrously large part of it is now in danger of disappearing for good. ... The forest produces more than 50 percent of all the rain that falls in the Amazon region, and it probably affects rainfall patterns far outside South America.

What is the biggest problem in the Amazon rainforest?

Deforestation. One of the largest, and most well known problems in the Amazon is that of deforestation. While trees have been cut for logging, development and human expansion, it is actually farming that is causing the most extreme and drastic deforestation among much of the Amazon rainforest.
