>but they represent trillions in services that likely can't just be replaced with technology. Why not? We probably have a lot of time before they become seriously unavailable. 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.
