This video fits in perfectly with a conversation we were having last class, population control. The world just reached 7 billion people, in the past 12 years the population has risen by one billion people. Yet, according to The Economist (and if they say it, it must be true) the planet will not see another jump this fast for the next few billions. Due to the declining birthrate in many countries, it will take 14 years to reach 8 billion and an additional 20 to reach 9 billion. The video calls this a world that is crowded, but stable. But can the Earth really hold 9 billion people before 2050? Is their ever a sustainable way to live with that many people inhabiting the planet? And what could be the cause of this decrease in birthrates?
