As a species we already can't live in harmony and equilibrium with the rest of life on the planet. We already can't organise ourselves well enough to give everyone a reasonable standard of living.
Based on that it's difficult to argue that the current exponential population growth is good or sustainable.
A practical and/or palatable solution doesn't exist. I've no doubt the situation will play itself out to a mass extinction, it's absolutely inevitable, just a question of when.
A practical solution does exist, through education and development to reduce the birth rate.
The birth rate is already below 1 in many countries around the world. Conversely they end up relying on immigration for economic growth and looking after their ageing populations.
The annual change in the world's population is now half that of what it was in 1970, and is decreasing year on year. This is where things like state aid, conflict resolution, education all come into play.
One interesting statistic is that in the last couple of years, the worldwide population of 65+ year olds exceeded under 5s for the first time. Birth rates are falling coupled with us keeping people alive for longer.
