The world is not only hungry, but also thirsty for water. This may seem strange to you,
__1__ nearly 70% of the earth’s surface is covered with water.
__2__ about 97% of it is sea water or salt water.
Man can only drink and use __3__ three percent- the fresh water that comes from plants,
lakes, underground and other sources(水源). And we can’t __4__ use all of that,
because some of it is in the __5__ of iceberg and glaciers(冰川).
Even worse, __6 o__f it has been polluted.
However, as we know today, this little amount of __7__ water,
which is hardly being replaced by rainfall, is still enough for us,
but our __8_ _for water is increasing quickly almost day by day. Only if we take actions
to deal with this problem now can we change the situation of water shortage.
One of the first __9__ we should take is to reuse water.
__10__ way is to make use of seawater by taking the salt out.
