That is only a small part of the 'cleaning up the environment.' And I am
not advocating filling in mines just because they are not currently
profitable. Only when the hole is of no use [other than storage of the
tailing that have been accumulating during the mining and refining
operations].
When ore is refine, waste is produce. When products made from the ore are
distributed, waste is produced.
Now 'waste' is a resource out of place. Much 'waste' could, if it were in
the right location, be used as a raw material in the manufacture of some
other product.
My 'cleaning up the environment' includes proper use or disposal of all
waste.

There are always diminishing returns. There will come a day when it costs
more than it yields.
All of those recovery methods have associated costs. Those who figure the
costs need to factor in all of the costs of producing that superheated
steam and getting it into the matrix, etc. The costs are NOT just the
dollar costs at the wellhead.

People are dying to produce the electricity that puts my words on your
screen. People died to produce that screen. People died to put the roof
over your head. People are dying.
I am not advocating 'killing' people who refuse to move to space.
I am saying that people will die in the effort and that is normal, natural
and not bad.

Nuclear energy is clearly the best choice for many things.
Solar energy is clearly the best choice for most things.
Using both in space is clearly the test choice.

Free choice is the only kind I favor.
Truely free choice. Really free, based on knowledge and logic.
Choices not forced by fear or hate or poverty.
How many of your choices in life have been free choices?

Using solar sails. Using solar furnaces. Using the m.v of the materials
boiled off duriing the refining process itself.

I would not coerce them.
I would not want them coerced by fear or hate or poverty into remaining on
earth either.
They. You. Me. We all are being coerced by circumstances, right now.

I want to see that which curently forces us to fear, hate and kill each
other removed. I want to see poverty defeated without the use of force on
any side.

I advocate the end of violence. Physical. And the end of the mental
violence of propaganda. The end of the use of greed, hate and fear to
control the masses.
Such violence is a crime againt humanity.
In a situation of plenty, there will be no need for such violence.

The use of force include the manipulation of other through the use of
hate, ignorance, fear, poverty.
