Description
The human population has been growing continuously since the end of the Black Death, around the year 1400, although the most significant increase has been in the last 50 years, mainly due to medical advancements, increases in agricultural productivity and the historically-unique availability of abundant cheap energy. The rate of population growth has been declining since the 1980s. Most contemporary estimates for the carrying capacity of the Earth under existing conditions are between 4 billion and 16 billion. In 2013 the human population was 7 billion. By 2025 the world population is expected to grow by an additional 1 billion. Depending on which estimate of overpopulation is used, human overpopulation may or may not have already occurred.The InterAcademy Panel Statement on Population Growth, circa 1994, has stated that many environmental problems, such as rising levels of atmospheric carbon dioxide, global warming, and pollution, are aggravated by the population expansion. Other problems associated with overpopulation include the increased demand for resources such as fresh water and food, starvation and malnutrition, consumption of natural resources (such as fossil fuels) faster than the rate of regeneration, and a deterioration in living conditions. However, some believe that waste and over-consumption, especially by wealthy nations, is putting more strain on the environment than overpopulation
