Population growth as a driving force for environmental problems
Population growth is known as one of the driving forces behind environmental problems, because the growing population demands more and more (non-renewable) resources for its own application. So why exactly does the human population expand to rapidly? To understand this, we must first explain a little about the difference between linear and exponential growth, in other words, add a little basic math to the equation.
Growth is usually thought of as a linear process: an increase by a constant amount over a period of time. The new amount is not influenced by the amount already present. For exponential growth, this is different, because the increase of a factor is proportional to what is already there. When cells divide, there will be a constant doubling of the cells already present. In terms of population growth, the numbers of people already present always influences the number of children born in any country. It is however not a simple matter of a constant doubling of the amount. Other factors, such as fertility and mortality rates, influence population growth, and the sexe and age of people already present, and rational decisions influence whether or not people will actually have one or more children.
