10 000 years ago, the world's population
was very little. Four hundred years ago,
the number were over 500 million.
Today, it's still growing more faster
than ever before. Now the problem
may be the greater one in the world.
How do you think of it? What
will happen to the world? What will
happen after a hundred years? This
means we must grow more food and
smaller families with fewer or healthier
children. If we won't do these, the
results will be very bad. There will
not have enough space to stand
in on the earth. This must be know
to us. |
