Crecimiento actual de la población

  The
 Grown
 of
 World
 Population
 
  Along
  the
  history
  of
  humans,
  there
  have
  been
  a
  more
  or
  less
  stable
 population.
  There
 were
 periodic
 plagues
 or
 famines
 that
 dramatically
 affected
 to
 the
 number
  of
  people
  and
  there
  were
  times
 of
  increasing
  of
  people.
  But,
  It
  was
  in
  1800
  when
  a
  big
 change
 happens,
 after
 industrial
 revolution
 there
 were
 a exponential
 growing
  of
 population
  In
  1800
  there
  were
  around
  one
  billion
  of
  people
  and
  there
  are
  actually
  around  seven
 billions.
 Some
 studies
 tell
 that
 in
 2050
 we
 will
 be
 9.1
 billions.
  I
  think
  that
  there
  are
  many
  causes
  of  this.
  The
  first
  one
  is
  the
  technical
  and
  tecnological
 impruves,
 they
 caused
 that
 we
 could
 reach
 an
 enormous production
 of
  food
  and
  better
  nutrition,
  medical
  advances
  caused
  that
  we
  have
  a
  better
  and
  longer
 life.
 
  But
 I think
 that
 there
 will
 be
 a
 lot
 of
 problems
 in
 the
 future
 because
 this
 growing
  can
  not
  be
  sustainable,
  there
  are
 limits
  in
  the
  resources
  and
  we
  are
  spending
  all
  of
  them.
 I
 read
 a
 study
 that
 told
 that
 the
 number
 of people
 and
 the
 use
 of
 the
 oil
 are
  related.
 We
 need
 the
 oil
 to
 keep
 our
 society
 going
 on,
 some
 day
 there
 will...
