More humans doesn't equal less resources, it equals more resources. The Earth isn't "running out" of anything, the idea of a carrying capacity for a technological species is ridiculous.
You're exemplar of this video subject: exponential growth can't go on forever, and you obviously didn't understand that. That's quite sad. Another article for reference:
Energy is the only resource that matters. With enough energy and technology we can recycle and transform whatever current raw physical materials we have available, no matter how inefficient it is.
With the population leveling off, I think the amount of physical materials needed at any one time will stop growing exponentially. Consumption will rates will still be increasing, but we can recycle the raw materials to keep the absolute amount needed within physical limits.
Sorry, I'm not an expert in that kind of stuff. But since resources don't get out of Earth, then the total loss of resources is 0.
Resource consumption is growing exponentially
Hmm, really? My computer is thinner, so is my TV (and probably my future car), I don't purchase paper any more (or almost don't purchase/use it) and I consume more digital products than physical ones. Yet, even if I purchase double of what I have the next year, I can't keep in that pace for too long.

Soil washed down to the ocean is lost to agriculture, if not lost to the planet itself, for instance. I'm quite sure that the planet will be OK whatever we do; the human race, however, may disappear quite easily.

Yes, and to build a new computer uses infinitely more than not building it in the first place. Your old computer isn't magically transformed back into a new one, or ore.
Every transformation needs energy. As long as energy is so cheap as it can be considered free and so largely available as it can be considered like infinite, everything's fine.
Just to remind you that a "service economy" relies on large, general availability of masses of almost free energy and resources. However, energy may soon turn more expensive and rarer.
We've been in peak oil for the past few years, and the production will began to drop any time now, probably within 3 to 5 years. There are no credible alternative to cheap fossil fuels, unfortunately, for most of their uses (transport, plastics, chemicals, fertilizers...).
So far, the way the world economy is currently organized cannot survive a massive change in energy availability. Particularly with the current accent put on economic growth. By definition, economic growth must stop at some point, by lack of resources, then go down. In the near future, economic recession will be the normal state of matters. How will we manage it? Without sinking into chaos? I really have no idea.
