50 years later the population has increased to eight billion without dire consequences (In the comments section) Yeah, right. Meanwhile the production of greenhouse gases is going through the roof, more people means more food required except that the oceans are about 10-20 years away from being completely fished out, water aquifers on all continents are practically drained dry, large cities are covering the world's arable land and taking it out of the equation, etc. We're living off tomorrow's resources to look after today's population. Tomorrow, when those resources will be required, the cupboard will be absolutely bare. Mass starvation and war will be the norm. And our civilisation will not survive.
