The cost of say, moving Miami and New Orleans would more expensive (ok well, impossible), or reversing the global food chain collapse, or de-acidifying the oceans, these are all currently either impossible or we would need to find some inadequate non-solution in the future costing far more. These problems will only get worse. If they were addressed in the 70s when they were first known about, it'd have been much easier. Yes, halting the destruction of the planet's ecosystem will cost some money darlin'. And it will always be more tomorrow.
