Good points, but be careful to understand that there is a difference between environmental problems that are "tangible" or directly affect our everyday experience, and environmental problems that are "abstract" or refer to imperceptible hazards or hazards predicted in the future.
When we're talking about the early days of environmental awareness, those problems with coal smoke, industrial smog, and dangerous infrastructure all fall into the first category. The push to break dependence on non-renewable energy falls into the second category (except where using non-renewable energy also has a perceptible effect on air quality).
