If there is something that has dramatically increased over the years, I will say it is the fact that the population size have dramatically increased over the years and seems like it is not slowing down anytime soon. In fact, I have come to understand that there are a whole lot of things that determine population growth. Whenever there is an economic growth, there will be a population growth and most times when there is an increase in birth rate, it will also increase the rate of population and much more.
