The Challenging Billions

CAMBRIDGE – The world is in the midst of the greatest demographic upheaval in human history. Although the human race took perhaps one million years to reach one billion people (around the year 1800), we have been adding successive billions every 10-20 years since 1960. The world’s population now stands at seven billion and is projected to reach 9.3 billion by 2050.
