To understand what Africa looks like it
does today
you have to start way back into Earth's
history, 310 million years ago to be precise
310 million years ago, during the late carboniferous the world looked nothing like today
there were no continent, like today, but rather one enormous super-continent called Pangaea
Pangaea had an area of around
125 million square kilometers
and Africa would've been right at the centre
Because Africa was at the center of Pangaea, it only had one third of it's current coastline
the rest being blocked by the surrounding land
There was one massive rain-forest, 25
times bigger than the Amazon
that covered the whole of Pangaea
The climate was warm,humid and oxygen levels were 168% higher than they are today.
There was one super ocean called Panthalassa that surrounded Pangae
and sea levels were around 80 metres higher than they are today
meaning that large parts of Africa were underwater
However, around 305 million years ago the
extension rain-forest of Carboniferous were destroyed by climate change, leaving
behind vast areas of desert.
