How to Kill Africa?

Jebus works too slow. Aids isnt fast enough. How to realistically destroy 90% of africa? Nukes = render land useless, and it has teh   diamonds and shit. Bullets = too expensive and not efficient.

Possible a fireball from Ryu or a Tiger uppercut?

Discuss.

Easy: You vote in a South African Government with an idiot prime minister and health minister who think you can cure AIDS by eating vegetables and/or having sex with a virgin. So much for self rule.
