“For the last 50 years, world population multiplied more rapidly than ever before, and more rapidly than it is projected to grow in the future. In 1950, the world had 2.5 billion people; and in 2005, the world had 6.5 billion people. By 2050, this number could rise to more than 9 billion.”
This shows that the population is increasing dramatically in the last few years. Eventually we could get into a point where we wouldn’t have any food/shelter for everybody. We need to focus on the population growth of countries to sustain the population.
