Millions of Elephants died in Kavango over millions of yearsIn 1930, as many as 10 million wild elephants roamed huge swaths of the African continent.
KAVANGO is home to Africa’s largest contiguous elephant population, as well as major populations of a wide range of species such as buffalo, hippopotamus, lion, lechwe, roan, sable,eland, zebra, wildebeest, waterbuck, puku, bushbuck, sitatunga, hunting dog, spotted hyena, and numerous other animal species of the Southern African savannas, woodlands and wetlands.
The ground vibrates as a herd of buffalo pass.
All these these animals died on Kavango land. Their remains seaped through the ground creating the largest basin in the world.
And the remains of these animals is what oil is made of.
Pretty easy to understand,
A Petroleum System being in place in Kavango is a foregone conclusion and, the quantity of oil in this ground must be be ENORMOUS.
This is my personal opinion.
