Cause Of Overpopulation

In this part of the essay, I will try to explain how population became overpopulation. Once, there were no people on earth. After several physiological changes, more and more people gradually occupied the earth. If we take the year Christ was born as a starting point, it took about 1804 (Worldometers) years until we passed the milestone of one billion people. In the late 1920’s (1927) (Worldometers) we were with two billion inhabitants. Only fifty years later we reached not less than five billion people (Worldometers). At the moment this paper was written, there were 7,38 billion people (Worldometers, 2015) in this world. This amount will increase to 10 billion by the year 2050 (Hoevel, 2008). To give you an idea, the current global situation

There have been three major technological revolutions. First there was the tool making revolution, next we faced the agricultural revolution and thirdly there was the industrial revolution. Due to these revolutions, people were allowed greater access to food. This resulted in a so-called population explosion. We will illustrate this explosion with the evolution of food processing through these three revolutions. Firstly, we started to use hunting tools like bows and arrows. This allowed hunters to hunt meat, which is a high-energy food. Also the transformation from hunting to farming led to increase of the overall food supply. There is no doubt that the industrial revolution offered many new opportunities. For example, the freezing of food led to a huge boost in food

Lack of family planning is an explanation for why the population growth in less developed countries is higher than in developed countries. In developed countries such as all the European countries we have a kind of standardized image of a family with one or two children. There are unwritten rules that say that most of us give birth to our children at an age between 25 and 35 years. In less developed countries, there is a clear lack of family planning. Children are seen as a way of future income or as social security for when their parents grow older.

Another cause I want to add is immigration. Many people move from less developed countries to more developed countries in search of luck. They immigrate to countries with the best available facilities like education, medical aid, employment and security. Immigration itself is not a cause of overpopulation, the overall population stays the same but it does ensure that certain areas are simply overcrowded. Allen (2008), provide us with the following additional information: "We have never in the history of the world experienced urban growth rates or metropolitan growth rates at the same level that we are experiencing now". In 2008, for the first time, more of us lived in cities than in rural areas. A megacity is a city with more
