I disagree.
I also worked in the environmental industry for many years; cleaning up leaking tanks spills, groundwater, etc.
While we may have addressed the very visible problems like petroleum spills, underground tanks leaks, smog, etc. we have also spread widely much more insidious and less easily/traditionally recognized pollutants like endocrine disruptors, pharmaceuticals, PFAS, pesticides, GHGs, fracking fluids constituents, heat, plastics, nanomaterials, etc. Some of these pollutants are much more widely spread, potentially dangerous in very low concentrations, and very difficult to remediate.
Those that pat themselves on the back thinking that we're living without a net negative impact because rivers don't burn anymore are fooling themselves.
