How is it not? Our civilization is burning through its resources at an unsustainable pace, in several major ways, and the obvious projection is overshoot and collapse.
Many people have faith that as-yet-unknown technological innovations will save us. Other people have faith that Jesus will return from heaven and save them. Faith sure must be comforting!
Given the knowledge we actually have, and the tools which are actually available, there appears to be a choice between working our way down to a lower standard of living now, gradually, as we transition to renewable energy, or dealing with an abrupt shock later, coping with the sudden chaotic arrival at a lower standard of living involuntarily, after the wheels have come off the fossil-fuel party all at once.
Cheap energy, fresh water, arable land/fertile topsoil, a functioning marine food web, functioning boreal ecosystems, pollinators, climate stable enough for consistent agriculture and reliable shipping. The more energy we use, the more CO2 we emit; the more we destabilize the climatic & ecological systems we depend on, the riskier a predicament we place ourselves in.
Given the ~40 years it will take to reach net-zero CO2 emissions, we will certainly miss a good number of climatic tipping points, and the environmental changes which result will add even more pressure to our existing risks. It is only sensible to buy ourselves as much time as possible by reducing energy demand. How do we do that? Well... that was my original remark.
