High population growth rate: the ever increasing population of Sub-Saharan countries (which is the fastest in the world) have cause spike in the rate of poverty. The population growth rate in comparison to resources is not sustainable, the overwhelming usage of available resources is more faster than it can be replenished leading to resource depletion or even extinction.

What would you suggest they do to stop the rate of reproduction in these countries? Most of them are poor and cannot afford items such as condoms or birth control to prevent this. Is outside interference needed to help these countries regulate reproduction somehow?
