Population Explosion refers the massive and sudden rapid rise of individuals within a species. The term is mostly used when referring to the world’s human population. The rapid growth of the world’s population over the past one hundred years results from a difference between the rate of birth and the rate of death 1. The human population will increase by 1 billion people in the next decade 1. The ever growing human population affects everyone around the world as it results in a strain on the environment 2. In order to better plan for the future, it is imperative that we know and understand the factors which affect population growth.
This dissertation aims to explain the respective roles that science, technology and society (STS) play in the problem of population explosion. It will mainly focus on the World’s population and that of South Africa.
Effects of science, technology and society (STS) on population explosion
Technology allows science to spread throughout the world, perform research and progress. As better technology is invented, scientists are able to perform complex, wider and more precise experiments. The results obtained from these science experiments are then used to make better technology. With better technology, scientists are now able to make stronger medications, thus are able to control diseases which results in less deaths and increased life expectancy. There is increased food production and better crops yielded. Better communication methods exist between individuals, thus resulting in easy sharing of information and resources. More people have access to better sanitation.
As a result of the abovementioned science and technology actions, this results in the human population exploding to a point where by the earth’s resources may not be enough to sustain all of us.
World Population
The current world population is 7.6 billion as of September 2018 according to the most recent United Nations estimates elaborated by Worldometers 3. The term “World Population” refers to the human population (the total number of humans currently living) of the world 3.
