The Duke of Cambridge keeps on running his mouth about population growth in Africa of all places.

It's likely that a "World City" will emerge in South Africa or maybe Nigeria. Possibly more than one in the region. Africa has many big cities. But nothing on the order of a New York, London, Hong Kong, Shanghai, São Paulo...

This means population growth. And just like every other region in the world it will have an impact.

The Duke can go bulldoze some London suburbs if he cares about nature.
