What are the environmental issues of overpopulation and what can we do to curb the problem? Overpopulation leads to a number of problems, including global warming and climate change. Scientists are concerned about the changing weather cycle and the continued rise in average world temperatures. Despite these concerns, different countries have signed agreements to help control global warming. In 2016, the top polluting countries signed the Paris Climate Agreement, which aims to limit the increase in global temperatures to 1.5 degrees Celsius.
While the global population has increased, not all countries are equally responsible for the damage to the environment. The consumption patterns and resource usage of individuals vary greatly. Some countries are producing more carbon dioxide than others, and others are not meeting the basic needs of entire populations. A study in 2009 revealed a strong correlation between population growth and carbon emissions. In North America, for example, the population increased by 4 per cent from 1980 to 2005.
While population increases in developed countries contribute to higher life expectancies, the problems that result from overpopulation are also affecting less developed countries. Population growth in developing nations is often exacerbated by a lack of resources and education, and a larger proportion of people live in less developed countries. As a result, the environment and ecosystems of developing countries are under greater pressure from rapidly growing populations. Additionally, humans are increasingly urbanised. In 2014, 54 per cent of the world’s population lived in cities.
