The African environment has always created high disease mortality. This was a blessing for Africa's living standards.
The rest of the article is not any better. Clark takes Jeff Sachs to task for overlooking the Malthusian situation in which Clark claims Africa finds itself. But it doesn't look like he has read Sachs carefully. In fact, the Malthusian trap is part of the big-time poverty trap Sachs' big push aims to tackle.
