Our current lifestyle is already causing a growing global temperature and a damage to the environment, that's reaching a global scale. How on earth is this current lifestyle 'sustainable'? I mean at this point, drastic measures at least in some areas, are in order if we want to preserve a somewhat tolerable future.
There is almost no corner of this earth, where you don't see beaches full of plastic or some kind of human influence.
Earth Overshoot Day (EOD), previously known as Ecological Debt Day (EDD), is the calculated illustrative calendar date on which humanity's resource consumption for the year exceeds Earth's capacity to regenerate those resources that year.
(...)
When viewed through an economic perspective, EOD represents the day in which humanity enters an ecological deficit spending. In ecology the term Earth Overshoot Day illustrates the level by which human population overshoots its environment. In 2018, Earth Overshoot Day is on August 1.[2]

This, this is already happening now. Our current lifestyle, is not sustainable, not in the long run.
Overpopulation is a problem IF we continue on the current path.
Firstly - humans far from consume all the resources we actually get out, in particular when we talk about food. Food is produced and destroyed ad continuum. We should produce what we actually consume, things would be easyer, but... everyone involved in these processes know this, so, who am I to tell them?
As for the current path as it is, yes, is pure death - but population growth and people movement will guarantee that there is no such thing as a
current path to follow. Current path of now will be much different from current path of the future.
Mind you, I'm not playing devils advocate here, I'm actually agreeing with you, more than you yourself perhaps. The current path will only get worse, which means it'll keep changing, the factors within, and how we relate to them. They'll only get more impossible
See, you see us spiralling towards doom, and you're looking for a solution. My approach is the usual: What solution exactly? The one that's right in front of us, that nobody will object to, that will be functionally implementable, and that - if it existed - we would have resorted to decades ago?
I know that I come off a bit jerky, but... you know.
We know what the solutions are. Well... there's on the surface, and below the surface, obviously...
On the surface, ban all air-travel, pretty much shut down all global trade (which require non stop air, trucking and shipping), and pretty much ban electronics.
Below the surface, however, we can untangle the web of human enslavement, the conditions that turn cobalt for example into a precious comodity, and not just another type of dust in the rock that we can make stuff from. Human economical models are always about the exchange, but at what rate and who sets it. And the more words I utter, the closer I'm getting to words such as "blade" and "heads" and "baskets", I know you don't like that much, but I can't help it.
I honestly, genuinely, truly believe - on a rational observational basis - that we will never fix any of this. Which is why I respond as I do initially: There will continue to be a class of people who rely on global trade, air travel, shipping, trucking, as well as slavery-based economy and all the delicious electronics it brings us. As populations grow, the privileged class will shrink in comparison, but stay stable as is now, or shrink gently, and the rest, the "resource-class" let's call them, will just... grow. Let's wait untill what is the projection, 2050s? to see if global population growth "naturally plateaus", if not, we're in for 11 billion, 12 billion, 14 billion, 18 billion and so on, year after year. If physically this cannot be sustained, we'll be looking at a similarily exponential "waste" of "surplus" (god I hate talking like this), where starvations of the past become marbles compared to the future.
Don't you just love these little exchanges?
