Yeah, here comes the point of controlversy.
1) You know what causes the population boom? Medical science. Now
it is more difficult for people to die than last time like in 1942,
where even smallpox is considered uncurable. With medical
improvements, people survives, and so the population
increases.
2) Yes, people should not die from poverty... but it is impossible
to provide for everyone, esp. South Africa, so big but bad
economy.
