2.1 Focusing on the main ideas
After
living
in
the
city
of
Las
Vegas
for
years,
Alison
Zeuschel
and
her
family decided to move to the
countryside. Their home hunting ended up in a very
small town in Arizona where they
purchased a house on 40 acres that was not only
off
the
grid,
but
without
access
to
any
(public)
utilities.
Just
imagine
the
challenges facing them, such as
generating their own power and hauling their own
water. However, they worked hard and
succeeded in making the adjustment in a
few months. In addition, they benefited
a lot from living off the grid there. Most
important of all, they came to know the
importance of conservation and learned
how
to
conserve
power
and
water
and
how
to
reuse
things,
etc.
In
other
words
they learned how to
live green.
