Sure, we did mount a concerted effort to solve the ozone problem. But that was a lot easier to do than what we need to do now. We needed to change the types of propellants used in aerosol spays and we needed to change the types of refrigerants we used - it was lucky that we had pretty equivalent and readily available replacements. But now to solve the myriad of challenges we face we need to reduce consumption of many different resources at once - sacrifices will need to be made. Big sacrifices in some cases. And given our current political climate, sacrifices aren't popular (not that they have ever been, but especially not now).
