The World’s Increasing Population
Population growth can be compare to the money in a fixed deposit account. The money in such an account will increases with accumulative interest...
In the year 2000, there were 10 times more people on earth than there were in the year 1700. This is how the world population grows so fast. No matter the reduced world population growth rate, there will still be significant increase in the world population. Over the years, the increase in population has led to the increase in emission of greenhouse gases.
Population growth can be compare to the money in a fixed deposit account. The money in such an account will increases with accumulative interest. The interest payments accumulated in such situation will eventually earn interest. If the money is left in such bank without withdrawal, this will lead to no stop increase in the overall amount. In population growth, new members of the population eventually produce other new members of the population, so the population increase exponentially as time passes.
The major difference between money and population is that money could increase without limits while population would not. Further increase in population will deplete the available resources because the world resources are limited. Human population or population of any species is constrained by the availability of food, water, land and other important resources.
The world population growth still stand at a staggering figure, although there have been decrease in population growth rate. It has been predicted that 2015 the world population growth rate will be 1%. But this 1% growth rate is going to be lead 7 billion people on earth. And in 2050, the world population is expected to be 10 billion, even at that rate. How long will “planet earth” support this kind of increasing population? And when will the world population reach the limit of its resources?
Research question: How can there be a population control on a global scale to reduce the increasing world population?
