Different in real

 In my spare time, I tried to study. I tried to more read about the environment, forest, emission, deforestation, and so on. This evening, waiting for my husband's never-ending meeting to work from home, I tried to looking and comparing two maps in Borneo Island. Took it from the ministry of environment and forest, I found it in 1715 pages of map forest between 2006 and 2012 is more open ground. 

2006 

2012

Can you spot the difference? 

We cannot know what is on open ground. Maybe it contains a former mine or maybe a meadow. When we need to renew the information in the map. We need to take verification in some samples.
