GeographyEcosystemsGCSEAQA Created by: HJ JuanCreated on: 18-02-19 13:19 Amazon Deforestation for Development 8 million km squared Since 1978, over 750 00 km squared has been destroyed by deforestation. 1 of 5 Causes Between 2000 and 2005: 70% - cattle ranching 20 - 25% - small-scale subsistence farming 5 - 10% - commercial farming i.e. soy and sugar cane 2 - 3 % used for timber 1 - 2 % mineral extraction and building new settlements 2 of 5 Environmental Impacts Slash and Burn tenchinques to clear large areas release CO2 into the atmosphere which conributes to global warming. Trees are a carbon sink - Amazon stores about 100 billion tonnes of CO2 so cutting them down releases more CO2 into the atmosphere. Brazil loses 55 million tonnes of topsoil each year due to soil erosion caused by soy farming. 3 of 5 Economic Impacts In 2008, Brazil made $6.9 billion from trading cattle. Brazil is the 2nd biggest exporter of soy beans. In 2015, the mining sector in Brazil generated 2.7 million direct and indirect jobs. The minerals sector equates to 21% of Brazils's exports. Local Brazilian rubber tappers have lost their livelihoods as trees have been cut down. 4 of 5 Social Impacts Indigenous Amazonian tribes are often forced to move due to the destruction of their habitats. The Murunahua were decimated by contact with loggers. It destroys the natural beauty of the area. 5 of 5
