It really depends on which lens you choose to view the issue. I'm probably making the discussion to complex by going on this tangent, but on a bigger scale, we are the only species in the universe that have this level of consciousness. In some sense, it's our duty to advance and explore to gain knowledge and understand the big questions.

To do that we need vast amounts of power and production, and have such a big output we need people. It's a fine balancing act. The population increasing isn't inherently bad. There's an argument to be made that we actually need more people to do it. However doing that lets to all sorts of problems: impact to the natural world, poverty, and so on.

On paper, we know and are producing enough energy, food, and have plenty of resources to increase the population. To do it safely, while keeping the world in good shape (ie managing climate), is a mix of being an engineering problem, political, social, fianancial, and so on.

To give you an analogy: some might argue that the housing crisis we currently have in the UK is because there are too many people. On the face of it, that's true. But the sensible answer is that we have too many people AND not enough homes. However the lack of homes is something that can be solved, but is held back by some of the issues I've already listed above.

Basically, it can be said that there is an overpopulation issue, but we have everything we need for more people, which would be beneficial to our ultimate goals as humanity, yet haven't been able as a global community to solve the other issues which make it a problem.
