If a radioactive substance is moved from one place, e.g. in the ground, to 
another place, e.g., in a smoke detector, how is that "adding" to it?

All the radioactive matter on earth is somewhere right now.  When we use it, we 
move it from wherever it is to some place else.  We don't create it.

Actually, you could make an argument that by mining radioactive substances and 
concentrating them into reactors, bombs, or other "products", you are making 
the world a bit safer, since it is easier to avoid exposure to reactors, bombs, 
etc, than to the same substances all spread out in the ground.

I never have understood quite why people get all wrapped around the axle about 
some things.  For example, we take aluminum out of the ground, where it is one 
of the more abundant elements in the earth's crust, and we make beer cans out 
of it.  But if we then put that aluminum back in the ground, e.g., by throwing 
empty beer cans into the dump, people get all in a lather about pollution.  
Why?  We are just putting the aluminum back where we found it.

And "wasting water".  People get all wound up about using too much water.  But 
it's not like it gets used up.  It's still there after whatever we use it for.  
And it comes back to us from rain, etc.  Why all the furor?  

Yeah, I know, there can be local shortages, but overall the total amount of 
water on earth doesn't really change, does it?

Alan,
 
     Yes of course.  Best 
not to add to it.  I'm sure you would agree.
 
      Cheers.
