Answer to Question 1

As discussed in the chapter an investigated above, sustainability depends on
exploiting a lesser or equal amount of a resource than is being produced. Recycling can
help in some cases to increase the availability of some sustainable resource. One obvious
example is the use of manure to fertilize farm fields. Instead of wearing the soil out, the
manure helps rebuild the soil.

Answer to Question 2

There are two major reasons that U.S. nuclear facilities are so expensive. First,
most existing nuclear power stations are one of a kind and are built almost entirely in the
field. Field construction is considerably more expensive than factory prefabrication. Second,
the regulatory climate for nuclear energy is far more stringent than for coal-fired plants,
causing a great difference in cost in meeting regulatory standards.
