Rob, Of course you are correct.  Whenever we can use less toxic or less risky materials, processes etc.,  those are the better options!   The issue is the degree of risk or damage, etc., to which we put our ecosystems, resources, and people and future carrying capacity.  No argument on your comment!! :>)  Thanks

"Lead and cadmium both have numerous valuable uses"

Pardon the tangent, but is it true that these toxic metals do have valuable uses?  I don't know much about all the uses for lead and less about cadmium but I do know that we once assumed mercury also had numerous valuable uses but now know that every, (nearly every?) use of mercury can and should be substituted with a less toxic material.  Any substitutes may initially cost more but when we consider the total cost to society perhaps higher initial costs actually become cost savings.
