Thank you for the explanation. Yes, indeed, it is mostly brown fields. And yes, Algeria and Libya are supplying the Southern Europe. They've replaced Russia as a major crude source.

Sadly, most of African countries have the corruption issues, and have the violent conflicts inside them, with extremist groups roaming around.

Regarding population, how do you see China? I see it critical. As they have a high GDP, but a low GDP per capita, with population declining.
