  cylindrical volume of about 50 cubic metres for
one tree.  Let's say
 that one person wants a piece of rosewood that is 50cm x 50cm x 1cm.
 That is 0.0025 cubic metres, so a single fully grown tree would
 satisfy 20,000 people once a year.  
 That's assuming that (a) all the pieces can be fit into the tree's volume
with
...
  no waste, (b) nothing is lost in cutting them out, and
(c) any part of the tree
...
  is perfectly suitable for any use.  Neither (a) nor
(b) is likely to be true, and,
...
  while I don't know rosewood, I know that with the
woods I do know
 something about, (c) is not true.

 I have nothing but wild guesses as to how much is wasted; for what it's
 worth, my wild guess is that the wastage is at least half the volume.

Yes, two people have challenged my assumptions. That is to be expected
really as I am no expert on wood.

It was just about getting an approximation to show that the "how can little
old me really make a difference" attitude *can* make a difference when there
are a lot of "little old me's". I am sure that the yield is far from
perfect, but I was just trying to show that even with some fairly optimistic
assumptions this attitude can have a big effect; if yield is 50% then the
figures double etc....
