Why did god create diseases?

[Chas]

That's not how it works. There is no 'built-in propensity' for lower birth rate. The only 'natural population control' is death.

Birth rates are partly a function resources, as is infant mortality.

Populations of animals are often cyclic, boom and bust phenomena.

Lower birth rates are a statistical fact of a developed society. One of Bill Gate's points for ending child poverty is that giving people enough food results in smaller families.

A population fat on resources becomes lazy > needs to try less to survive > reverses the rules of natural selection

The bust and boom phenomena makes the point better... a species exceeds it's resources and dies back... it's a natural control. It's how nature works and that's pretty damn cool.

Like I said... dissatisfaction with that makes you a fantasist.

The lower birth rates of developed societies is explained sociologically, not biologically.

The boom and bust cycles of animal populations has nothing to do with birth rates - it has to do with death rates. It's about resources.

This is well illustrated by predator/prey cycles:


Also well illustrated by disease cycles. An epidemic of disease will kill off enough of a population so that the population density will no longer support the disease transmission. The disease organism population subsides, the victim population rebounds - just like a predator/prey cycle.


Your fantasy is invalid.
