If I was making the decision, I'd want a balance between the two, but apparently I'm not allowed that in this thread.

Nope, not allowed damn it. If I had allowed a middle ground option everyone would have taken that, (including me) and I'd never be able to hear what people prioritise. That would make me sad.
I prioritise looking after old people over freedom to have as many children as people like. I've said it in a million threads before. There's too many people, stop making babies damn it world. *regains composure*.
Actually I read a book recently that had a chapter on population issues, the chapter was long, so I'll summarise.
The amount of energy we can use is limited by the sun, and as far as we are aware we're not going to be able to increase the amount of energy the sun produces. At best we can become better at harnessing it.
This in effect means there's a finite amount of energy on earth. Lets get rid of a few myths first. ALL of the suns energy gets used, all of it, every last joule. Just not all of it is useful to us. Some powers the wind, some heats up the ground, some gets sucked into life process' like plant growth. But it does all do something.
This in effect means that everytime we add an extra person to the world, that much more energy is being used in their life processes and the resources used to keep that person alive. Now since energy can't be created or destoryed, that means the energy must come from somewhere.
It's interesting to note that as humans increase in numbers and as we seem to require a lot more resoures per person than we used to, the number of animals has gone down, as has the number of trees and plants. Because simply put.. energy normally trapped in other life cycles are being diverted to our own, and was suck in more and more energy into our own needs.
Currently the effect is being slowed by fossil fuels, which are fall all intents and purposes, giant batteries. Energy the sun sent down long ago stored up in the dead remains of life long gone. So we're suplimenting the energy already being sent down by digging up these batteries and using them too. The problem hits that these batteries run out is when issues really start. People rant on about technology saving us, but well what technology is that. Sadly as I said early the energy sent down by the sun is finite, nothing we can do will change that, wind just takes energy out of the masses stored in the worlds wind system, luckily that won't be missed.
Solar creates a brand new issue. Most people aren't aware just how many panels you need to create a decent amount of power. Solar panels produce energy in an exact proportion to how much land you cover. If you want enough panels to power say industry and factories that make all our pretty things like cars, and tractors. You need to cover vast areas of land in panels. Meaning bingo.. we have to take energy away from plants that would be otherwise growing there.
It's pretty much the same everywhere, new technology still has to get it's energy from somewhere.. all energy we get (except nuclear fission) comes in the form of heat and light from the sun. New technology just finds new ways of diverting the energy towards us, and away from someone or something else.
So back to population.. if we keep up the number of people, we keep risking selfishly having all the energy arriving the planets way, things die off because we do that. It's not a case of 'when the population gets to large'. It's too large now, and it's why things are dying off. As some of the worlds poorer countries are trying to catch up with th comfort of living as the 1st world.. that many more people will be using resources per person as the first world already does. Technology or not.. we still aren't creating energy to sustain us that isn't dependant on what we get from the sun, I'm not just talking electrical energy, I'm talking energy needed to grow plants, energy needed to manafacture things, energy needed for biological functions (that we get through food).
Even fusion wouldn't be able to help with it all. Having too many kids is shooting ourselves in the foot. Let's look after the folk who are already here first.
