There may be additional oil reserves inland in the Taoudeni basin, although the harsh environment will make extraction expensive. 
 Hello! I have been assigned a 3 page report on Mauritania and I am clueless. Could you help me with some interesting facts about Mauritania? 
 Please tell me more! This is quite interesting to me. 
 Interesting, apparently they don't produce enough oil I take it? Tell me more of their economy if you could... 
 Oh, that makes sense. I didn't realize it was that harsh. Thank you so much for assisting me today. This will really help my report.
