The current rate of world population growth has reason to give us cause for alarm. Every fifteen to twenty years, the world population increases by a billion people. That is the staggering reality of the world population growth. In fact, in the year 1999, it was estimated that the world population surpassed six billion then. It is difficult to forecast populations exactly of course, and as population growth is a derivative rate from the population itself, growth is also difficult to estimate.
Population growth is difficult to estimate because factors such as natural disasters may skew the number of deaths each year through earthquakes, typhoons and famine. Other factors such as migration, and when census in different countries are taken may also affect data. (If for example, a million people in the United Kingdom migrate due to Brexit into Europe, and the census dates between the United Kingdom and Europe are different, a million people could lapse in between somewhere.)
At this current rate of growth the world population is expected to reach eleven billion by the turn of the century. By 2200 we would double the existing world population. The world population growth at its current rate is hence unsustainable. We must take measures to curb it, it appears. And why? If you think about it, at its current level there are already people who suffer from poverty and hunger and do not have enough to eat. The world’s resources cannot feed so many people at its current level; how is it going to feed an additional billion or two?
It is unsurprising then that there have been greater publicity towards a move towards less meat, more vegetarian and even vegan diet. Meat such as beef from cows accounts for nearly a quarter of greenhouse emissions. If we were to reconsider our diet, some reason that it just might allow us to produce enough to feed a growing world population.
Population growth also means a drive towards accumulating more skills for employment. When there are people than there are jobs, it means greater competition, and a need to be more skilled and creative in promoting one’s skills and knowledge. If you were a footballer, for example, you need to have more football skills on the pitch, but also to know how to market yourself. It is no point being the best footballer if you do not take advantage of the opportunities to make income through sales of jerseys, advertising, promoting products and off the pitch.
So that is the case for footballers, but what about the rest of us? We could look at developing more general skills. For example, just because you are an accountant does not mean you can’t have musical interests. You may be an actor, but have good computing skills, Or if you are an artist, there is nothing stopping you from doing other non-artistic courses in your free time. These skills may come in handy and give you the edge over someone else with the same qualifications. The hardest part is finding time to practice what seems like irrelevant skills to the job, but developing these may be a good way to stand out in an ever-populated world!
