The solution is obvious. We'll have tree farms. Growth hormone and
annual harvest.
There's another obvious solution. We can cut down on the wood products
by synthesizing products that would have been obtained from trees. All
in all it's matter conservation I'm talking about.
Now people don't have to complain about a recession due to job loss
in the forestry industry. Since matter is conserved, the people can
just shift to a job dealing with different matter. We don't need
as many tree cutters, but we need people who can manufacture things
that used to be made from wood. In fact, factories can be made to
produce FASTER than forests. We'll need more employees than ever.
