changes / threats
-
selective logging of mahogany trees damages nabouring trees leading to open gaps exposed to sunlight and wind meaning they dry out quicker and can lead to more frequent wild fires
-
-
2,400 trees are cut down every minuit

Belo Monte Dam is a hydroelectric dam which floods over 640km sqared of the rainforest.. It will not only damage the lives of thousands of people, indigeanus people who rely on the river will be forced to relocate. It will leave populations withought fish and water and force many people into jobs such as logging and cattle ranches. But it will also drematicly damage the rainforest with the flooding. It will lead to the extingction of at least 10 speacies and the moscetos which carry deaseses like maleria will be able to bread uncontrolably . The decomposing vegitation from the flooded forest would release methan which is 25x more potant than C02.

Brazilian ethanol produced by sugar cane reduces greenhouse gass emisions by up to 90%. However, this has also been a reason for deforestation.

Over half of the Brazilian Amazon is now part of national parks or indijenous lands. For example, the Para Rainforest reserve preserves 15 million ha of rainforest.

Brazil refused to source cattle from ranches within 10km od deorestation. This foreced the cattle industry to improve its practises
The Brazilian space agency have launched a saterlight which moneters change in forest in real time, producing a report on deforestation hotsports for law inforcement every 2 weeks. It is estimated that this has prevented the deforestation of 59000 square km of rainforest between 2007 and 2011

affects of change
Brazil is the worlds 4th largest climate polluter with 75% of their greenhouse gas emissions attributed to deforestation and land use change
a 2 dagree temperiture rise above pre industrial levels will see 20-40% of the Amazon die offf within 100 years
the particals created from burning of forest increase the density airborn airosels around which water vapour condences. Resulting in smaller droplets in clowds which are too small to precipitate meaning less local rain
The albedo effect happens when forrest is feforested and the land is now much lighter in couler and reflects the light rather than absorb it. Forests absorb 11% more solar radiation than pasture lands.

The capacity of thr Amazon rainforest to absorb carbon is declining. In the 1990s it drew down over 2 billion tons of C02 overy years but in 2015 it decreased to 1 bllion.
