When will economemers learn that continuous market growth is unsustainable after a certain threshold is crossed, when there becomes no net benefit of keeping a society alive. We already see the difficulty in sustaining the labor market with the advancement modern technology, compounded by the self-serving nature of companies/governments. 

The problem is that we have reached a juncture in which it has become extremely cheap to exploit the resources of the Earth while simultaneously leaving pollution in one's wake. These types of technologies would need to be scaled up to many nations in order to have an appreciable impact on the Earth's environment and population to effectively stave off any disaster/crisis. This leaves the plans much more vulnerable to the intricacies of global politics, budgeting, human rights, etc.

On the contrary, a method of population control could be spread easily, efficiently, and silently, with little fuss or strife regarding its use.
