Some resources are by definition are not sustainable. Fossil fuels are the best example, since they represent compressed biomass that takes millions of years to produce.
The most worrying resource that isn't usually thought of are ecosystem services. The ocean produces an abundance of wild caught food, but also various cycles provide oxygen, consume co2, and coral reefs buffer shorelines against erosion. We degrade those systems with abandon, but they represent trillions in services that likely can't just be replaced with technology.

The Earth is huge. Imagine if all oxygen production on Earth stopped tomorrow. We would still have enough oxygen in the atmosphere that would last 1000 years at current consumption (obviously you couldn't live for a 1000 years though). Humanity has progressed immensely in the last 200 years. I can't imagine where we will be in 500.
