The satellite images below from NASA, show how parts of the Amazon have changed over a decade of deforestation. 

The before and After images are 2000 v 2012

The before and after images show 2000 v 2012 for the state of Rondônia in western Brazil. 

The scale of this can be lost, as it is a satellite image. 

Rondônia lost 2.9 million hectares of tree cover from 2000 and 2012, according to Global Forest Watch.  

That is 29,000 square kilometers lost in a decade – that is an area the size of Belgium, lost, in just one area of Brazil
