Supply and Demand.
Diminishing resources + increasing demand = increasing prices = limited growth.
Climate change is essentially the pollution of the ocean with excess heat, which in turn is convertible to at least as much energy as we currently consume. To harness this energy requires a one time capital investment that will payout over 60 years and will not deplete the resource. Over that span the only cost will be debt servicing and maintenance.
Straighten out the top line in Figure 1 and how does that impact the rest of the chart?
Dissolved in ocean water and in its sediments are all of the other minerals we required for a sustainable existence.
Oceans also are the source of much of the food we need and were the original source of the oxygen we breath and still provide about 50 percent; all of which is at risk due to the heat pollution we are doing nothing about.
Gail your prediction of collapse may well come to pass but the major reason for it will have been a misallocation of capital.
