This paper summarizes research on the effect of population growth on environmental quality. Land transformations induced by the spatial expansion of agriculture are probably the major route by which population growth has affected features of the natural environment. These transformations are not automatic and their extent is influenced by social institutions.

Many people worry that population growth will eventually cause an environmental catastrophe.

While the causes are complex, one significant contributor to the problem is population growth. Understanding the relationship between population growth and environmental issues may be the first step toward identifying real solutions. Population growth is the increase in the number of people living in a particular area. Since populations can grow exponentially, resource depletion can occur rapidly, leading to specific environmental concerns such as global warming, deforestation and decreasing biodiversity.

A United Nations report released in puts the current world population at 7. By this number is expected to increase to 8. With a handful of countries being primarily responsible for this growth, about 83 million people are being added to the population each year even though it is expected that fertility levels will continue to decline. Nigeria, the fastest growing country, is expected to become the third largest country in the world by , exceeding the population of the USA. A growing population with disparities in distribution can add strain to the environment to feed people.

The current population of the Earth is almost 7. While a lot of positive steps are being taken to better ensure the sustainability of humans on our planet, the problem of having too many people has made lasting solutions more challenging to find. The term overpopulation is used to describe a situation in which the world or area has a population so large that the people there are suffering as a result. In other words, the population exceeds the region or planet's carrying capacity--the number of people, other living organisms, or crops that can be supported without environmental degradation. Their suffering may include a shortage of food, limited access to healthcare and other public services, overcrowding, and high unemployment. Overpopulation is largely attributed to trends stemming from spike in birth rates in the mid 20th century.

The number of people on Earth, where they live, and how they live all affect the condition of the environment. People can alter the environment through their use of natural resources and the production of wastes. Changes in the environmental conditions, in turn, can affect human health and well-being. Human demographic dynamics, such as size, growth, distribution, age composition, and migration of population, are among the many factors that can lead to environmental change. Consumption patterns, development choices, wealth and land distribution, government policies, and technology can mediate or exacerbate the effects of demographics on the environment.

There are calls to set population targets for Australia. These often relate to the number of people that would be the optimal population, rather than a sustainable population. There are limits in terms of the ability of the environment to supply resources and the ability of it to absorb waste products. Some commentators argue that we have already exceeded sustainable population levels for Australia.
