1. Human overpopulation

   Human overpopulation (or human population overshoot) is the hypothesis that human populations can become too large to be sustained by their environment or resources in the long term. The topic is usually discussed in the context of world population, though it may concern individual nations, regions, and cities. Since 1804, the global human population has increased from 1 billion to 8 billion due to medical advancements and improved agricultural productivity. According to the most recent United Nations' projections, "[t]he global population is expected to reach 9.7 billion in 2050 and 10.4 billion in 2100 [assuming] a decline of fertility for countries where large families are still prevalent." Those concerned by this trend argue that they result in levels of resource consumption and pollution which exceed the environment's carrying capacity, leading to population overshoot. The population overshoot hypothesis is often discussed in relation to other population concerns such as population momentum, biodiversity loss, hunger and malnutrition, resource depletion, and the overall human impact on the environment.Early discussions of overpopulation in English were spurred by the work of Thomas Malthus. Discussions of overpopulation follow a similar line of inquiry as Malthusianism and its Malthusian catastrophe, a hypothetical event where population exceeds agricultural capacity, causing famine or war over resources, resulting in poverty and depopulation. More recent discussion of overpopulation was popularized by Paul Ehrlich in his 1968 book The Population Bomb and subsequent writings. Ehrlich described overpopulation as a function of overconsumption, arguing that overpopulation should be defined by a population being unable to sustain itself without depleting non-renewable resources.Modern proponents of the concept have suggested that overpopulation, population growth and overconsumption are interdependent and collectively are the primary drivers of human-caused environmental problems such as climate change and biodiversity loss. Many scientists have expressed concern about population growth, and argue that creating sustainable societies will require decreasing the current global population. Advocates have suggested implementation of population planning strategies to reach a proposed sustainable population. Overpopulation hypotheses are controversial, with many economists, demographers, and environmentalists disputing the core premise that the world cannot sustain the current trajectory of human population. Annual world population growth peaked at 2.1% in 1968, has since dropped to 1.1%, and could drop even further to 0.1% by 2100. Based on this, the United Nations projects the world population, which is 7.8 billion as of 2020, to level out around 2100 at 10.9 billion with other models proposing similar stabilization before or after 2100. Some experts believe that a combination of factors (including technological and social change) would allow global resources to meet this increased demand, avoiding global overpopulation. Additionally, some critics argue that attempts to blame environmental issues on overpopulation oversimplify complex social or economic systems, or place blame on developing countries and poor populations—reinscribing colonial or racist assumptions and leading to discriminatory policy. These critics often suggest overconsumption should be treated as an issue separate from population growth.

1. Human overpopulation

   Human overpopulation occurs if the number of people in a group exceeds the carrying capacity of the region occupied by the group. The term often refers to the relationship between the entire human population and its environment, the Earth, or to smaller geographical areas such as countries. Overpopulation can result from an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources. It is possible for very sparsely populated areas to be overpopulated if the area has a meager or non-existent capability to sustain life. 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 and increases in agricultural productivity. Although the rate of population growth has been declining since the 1980s, the United Nations has expressed concern on continued excessive population growth in sub-Saharan Africa. As of June 4, 2013 the world's human population is estimated to be 7.089 billion by the United States Census Bureau, and over 7 billion by the United Nations. Most contemporary estimates for the carrying capacity of the Earth under existing conditions are between 4 billion and 16 billion. Depending on which estimate is used, human overpopulation may or may not have already occurred. Nevertheless, the rapid recent increase in human population is causing some concern. The population is expected to reach between 8 and 10.5 billion between the year 2040 and 2050. In May 2011, the United Nations increased the medium variant projections to 9.3 billion for 2050 and 10.1 billion for 2100.
