Dear Hanna,
The topic about gold I think you do not need someone living in Ghana to tell you this. The internet is fully of detail explanation of gold, it use, etc...
But if you want to know about how gold is extracted in Ghana, and about how it affects the various communities in Ghana, then ok .. I think we can help.
For example, the impact on the lives: whether, it is enriching the various communities or impoverishing them, the impact on the environment, if the people had their way, would they still extract the gold or leave it where it is ??
How is gold extraction activity affecting the water bodies in Ghana, what about the farm lands ?? are these what you want to know ?? or you are just interested about the quality of the Ghanean gold ??
Let me know !
