This rise in population density has been consistent with rising living standards and a better quality of life. However, others are concerned that a rising global population density could lead to a strain on resources, leading to food shortages, congestion and loss of the environment. Source: Wikipedia.

Benefits of a rising population density Economies of scale in national infrastructure. Urban areas tend to be more energy efficient. Rural areas have a higher per-capita energy composition. For example, in remote areas, people will read article to tne a long way to shops. In heavily populated urban areas, shops and facilities are likely to be within walking distance.

However, if you look at suburbs, the situation is different with higher incomes leading to more energy consumption without the density of close housing in urban areas.

Technology has mitigated the negative forecasts of many who feared rising population. Malthus predicted in the Nineteenth Century, a rising population would lead to food shortages. The population has risen considerably, but areas of high population density have not seen the food shortages because of improved yields from agriculture and the ability to trade food. Technology enables higher living standards with lower levels of population. For example, in the s, UK fEfects were often using coal fires to keep warm, leading to smogs and high levels of pollution in cities, but these smogs have been cleaned up. In theory, there is the scope for meeting energy needs from renewable energy, such as solar power.
