@douginamug Yes, it's very complicated macroeconomically, specially if we follow the path of "every country for itself". That's why we need big international agreements on this. All damages to the environment should be taxed progressively to avoid loading most burden on people who can't afford it. But the most important goal is to invest all that into quickly substituting what we have now for zero harm to the environment. In the meantime we have to keep raising awareness and acting accordingly.
