AMERICA Is @Capacity & Is Overpopulated

The phrase "at capacity" in American economic debates over overpopulation reflects concerns that infrastructure, housing, and ecological resources cannot sustain further population growth, though mainstream economists argue the core issue is distribution and policy rather than a true physical limit.Economic Arguments for Capacity ConstraintsHousing Shortages: High demand and lagging supply drive extreme unaffordability in major metropolitan areas.Infrastructure Strain: Public transit, roads, water systems, and schools face localized overcrowding and maintenance backlogs.Environmental Limits: Rapid consumption and suburban sprawl increase carbon footprints and stress local ecosystems.Counterarguments and Structural RealitiesGeographic Distribution: Much of the United States remains sparsely populated; congestion is concentrated in specific urban hubs rather than nationwide overpopulation.Demographic Decline: Birth rates are below replacement level, meaning immigration is required to prevent a shrinking workforce and economic stagnation.Productivity and Innovation: Market economies historically adapt to density through technological innovation and capital investment rather than running out of fixed carrying capacity.If you'd like to explore this further, let me know if you want to focus on:Housing market dynamics and zoning lawsDemographic trends and labor force impactsEnvironmental carrying capacity and resource economics.

Trumpf-Lebensraum - Why DJ Trump Wants Greenland & Why AMERCA Needs It

America needs Greenland because it is @ Capacity and needs more Living Space or Lebensraum in the form of "Carrying Capacity"; Lebensraum (Background); Trump is German.His Mother was Scottish.Both countries struggled with overpopulation hence why Trump's parents emigrated to the USA for opportunities not avaiable in their homecountries Germany and Scotland. The renowned German geographer Friedrich Ratzel coined the term in 1901. He and many others at the turn of the century believed that a nation had to be self-sufficient in terms of resources and territory (a concept known as autarky) to protect itself from external threats.

Ratzel and others were also deeply influenced by the new work of Charles Darwin and his theory of natural selection. However, they mistakenly applied the concept to nation states, contending that, like the species Darwin studied, nations too struggled over resources for survival where only the fittest would win. Ratzel argued that the development of a people was influenced by their geographic situation, and that a society who effectively adapted to one geographic territory would logically expand the borders of their country into other territory. Pointing to the British and French Empires and to American “Manifest Destiny,” Ratzel contended that Germany required overseas colonies to relieve German over-population. The East presented another logical outlet for growth. Long before the Nazi period, many Germans looked to eastern Europe as the natural source of their Lebensraum. Beginning in the Middle Ages, the social and economic pressures of over-population in the German states had led to a steady colonization of Germanic peoples in eastern Europe. Increasingly by the twentieth century, however, scholars and the public alike began to view the East as a region whose vast natural resources were wasted on racially “inferior” peoples like Slavs and Jews. A biological view of Lebensraum resonated with an inaccurate historical view of the German role in the East during the ancient and medieval periods. Expansionists clung to this mythic German “history” in eastern Europe, arguing that these regions were actually lost German lands. As one German publication stated in 1916, “we Germanic people build up—create—the Slav broods and dreams—like his earth.” Lebensraum and World War I Ironically, during World War I, the German state achieved its goal of conquering Lebensraum in the East, extending German dominance as far east as Minsk and constructing a military dictatorship dedicated to exploiting and altering the landscape. The eventual German defeat in World War I resulted in not only the loss of all its overseas colonies but also the eastern military “kingdom” known as Ober Ost. The war and accompanying deep sense of loss heightened the German conviction that its salvation lay in the East. Hitler, himself a World War I veteran, recognized the effect that the British naval blockade and materiel shortages at home had had on the home front, weakening morale and increasing civilian suffering. This contributed, in many conservative Germans' minds, to the “Stab-in-the-back” explanation for Germany's defeat which blamed the loss not on military failures but on Jews, liberals, war profiteers, and others on the home front who had compromised the war effort. Hitler vowed that Germany would never again be defeated by a lack of resources. In his unpublished second book, he lamented that “the German people is today even less in a position than in the years of peace to feed itself from its own land and territory.” In 1936, he glowingly spoke of the “incalculable raw materials” in the Urals, the “rich forests” of Siberia, and the “incalculable farmlands” of the Ukraine. Lebensraum and the Nazi State In the Nazi state, Lebensraum became not just a romantic yearning for a return to the East but a vital strategic component of its imperial and racist visions. For the Germans, eastern Europe represented their “Manifest Destiny.” Hitler and other Nazi thinkers drew direct comparisons to American expansion in the West. During one of his famous “table talks,” Hitler decreed that “there's only one duty: to Germanize this country [Russia] by the immigration of Germans and to look upon the natives as Redskins.” The concrete measures taken by the Nazis to secure their Lebensraum demonstrate the very real power of ideas. Again, in his second book, Hitler wrote that Germany should “[concentrate] all of its strength on marking out a way of life for our people through the allocation of adequate Lebensraum for the next one hundred years.” Naturally, the inferior races that occupied this region must be removed, both Slavs and Jews. The drive to clear the East of inferior populations in preparation for German colonization led to intensive planning for the mass starvation of over 30 million people there. Policy guidelines issued before the invasion of the Soviet Union stated unequivocally that “many tens of millions of people in this territory will become superfluous and will have to die or migrate to Siberia… With regard to this, absolute clarity must reign.” Known as the Generalplan Ost, this set of economic and demographic plans placed the necessity for Lebensraum and the colonization of the East at the center of the invasion. By blaming Jews and Bolshevists for the “backwardness” of the region, the plans also reinforced other forms of Nazi antisemitism demanding the removal of Jews from the territory and eventually their physical destruction. The concept of Lebensraum was not solely responsible for the Holocaust, but powerfully connected a variety of imperialist, nationalist, and racist currents that would contribute to the murder of the Jews of Europe. is a German word that means "living space". It is a historical and geopolitical theory. The concept argues that a nation or a people needs a certain amount of land and natural resources to grow and survive.You can read more about the core details and history of this concept in the Holocaust Encyclopedia definition of Lebensraum.Origins of the ConceptCoined in 1901 by German geographer Friedrich Ratzel.First used as a biological idea about animals and plants needing space to live.Later applied to human societies and cultures using social Darwinism.Used during World War I by German leaders who wanted to expand their empire in Europe.Nazi Germany and World War IIAdopted and twisted by Adolf Hitler and the Nazi Party.Used to justify taking land in Eastern Europe and the Soviet Union.Claimed that the German "master race" deserved more land for farming and living.Led to the violent removal, enslavement, or mass murder of Jewish, Slavic, and other local populations.Served as a main reason for starting World War II in Europe. AMERICA simply is pverppoulated and its growing population and economy need more "Lebensraum" or "Living Space". The United States of America has reached its "Carrying Capacity" @ Capacity ; America is now at Capacity economically speaking. When an economy is "at capacity" means it has reached its highest sustainable output using current workers, factories, and technology without causing high inflation. At this point, supply cannot easily rise to meet extra demand, which often causes prices and wages to go up.Key Signs of Capacity LimitsLow unemployment: Jobless rates drop near the lowest stable level (known as NAIRU).High factory use: Industrial and manufacturing plants run near or above 85% of their total potential.Rising inflation: Prices and labor costs climb because goods and workers are hard to find.Inelastic supply: Firms cannot produce more units quickly unless they spend time and money building new facilities.Economic Impact and PolicyOutput gaps: When demand pushes production past normal limits, it creates a positive output gap and forces prices higher.Central banks: Policymakers track these limits to decide when to raise interest rates to cool down spending.Long-term growth: To push past a capacity ceiling, an economy needs new technology, better skills, or more physical capital. The carrying capacity of an ecosystem is the maximum population size of a living biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available, over a fixed amount of time. The carrying capacity is defined as the environment's maximal load,[clarification needed] which in population ecology corresponds to the population equilibrium, when the number of deaths in a population equals the number of births (as well as immigration and emigration). Carrying capacity of the environment implies that the resources extraction is not above the rate of regeneration of the resources and the wastes generated are within the assimilating capacity of the environment. The effect of carrying capacity on population dynamics is modelled with a logistic function. Carrying capacity is applied to the maximum population an environment can support in ecology, agriculture and fisheries. The term carrying capacity had been applied to a few different processes in the past before finally being applied to human population limits in the 1950s.[1] The notion of carrying capacity for humans is covered by the notion of sustainable population. An early detailed examination of global limits on human population was published in the 1972 book Limits to Growth, which has prompted follow-up commentary and analysis, including much criticism.[2] A 2012 review in the journal Nature by 22 international researchers expressed concerns that the Earth may be "approaching a state shift" in which the biosphere may become less hospitable to human life, and in which the human carrying capacity may diminish.[3] This concern that humanity may be passing beyond "tipping points" for safe use of the biosphere has increased in subsequent years.[4][5] Although the global population has now passed 8 billion, recent estimates of Earth's carrying capacity run from two to four billion people, depending on how optimistic researchers are about the prospects for international cooperation to solve problems requiring collective action.[6] Origins In terms of population dynamics, the term 'carrying capacity' was not explicitly used in 1838 by the Belgian mathematician Pierre François Verhulst when he first published his equations based on research on modelling population growth.[7] The origins of the term "carrying capacity" are uncertain, with sources variously stating that it was originally used "in the context of international shipping" in the 1840s,[8][9] or that it was first used during 19th-century laboratory experiments with micro-organisms.[10] A 2008 review finds the first use of the term in English was an 1845 report by the US Secretary of State to the US Senate. It then became a term used generally in biology in the 1870s, being most developed in wildlife and livestock management in the early 1900s.[9] It had become a staple term in ecology used to define the biological limits of a natural system related to population size in the 1950s.[8][9] Neo-Malthusians and eugenicists popularised the use of the words to describe the number of people the Earth can support in the 1950s,[9] although American biostatisticians Raymond Pearl and Lowell Reed had already applied it in these terms to human populations in the 1920s.[11] Hadwen and Palmer (1923) defined carrying capacity as the density of stock that could be grazed for a definite period without damage to the range.[12][13] It was first used in the context of wildlife management by the American Aldo Leopold in 1933, and a year later by the American Paul Lester Errington, a wetlands specialist. They used the term in different ways, Leopold largely in the sense of grazing animals (differentiating between a 'saturation level', an intrinsic level of density a species would live in, and carrying capacity, the most animals which could be in the field) and Errington defining 'carrying capacity' as the number of animals above which predation would become 'heavy' (this definition has largely been rejected, including by Errington himself).[12][14] The important and popular 1953 textbook on ecology by Eugene Odum, Fundamentals of Ecology, popularised the term in its modern meaning as the equilibrium value of the logistic model of population growth.[12][15] This is a graph of population change utilizing the logistic curve model. When the population is above the carrying capacity it decreases, and when it is below the carrying capacity it increases. The Verhulst equation is a first-order ordinary differential equation. Combined with an initial value The logistic growth curve depicts how population growth rate and carrying capacity are inter-connected. As illustrated in the logistic growth curve model, when the population size is small, the population increases exponentially. However, as population size nears carrying capacity, the growth decreases and reaches zero at K.[21] What determines a specific system's carrying capacity involves a limiting factor; this may be available supplies of food or water, nesting areas, space, or the amount of waste that can be absorbed without degrading the environment and decreasing carrying capacity. Population ecology Main articles: Population ecology and Population dynamics See also: Ecological overshoot Carrying capacity is a commonly used concept for biologists when trying to better understand biological populations and the factors which affect them.[1] When addressing biological populations, carrying capacity can be seen as a stable dynamic equilibrium, taking into account extinction and colonization rates.[17] In population biology, logistic growth assumes that population size fluctuates above and below an equilibrium value.[22] Numerous authors have questioned the usefulness of the term when applied to actual wild populations.[12][13][23] Although useful in theory and in laboratory experiments, carrying capacity as a method of measuring population limits in the environment is less useful as it sometimes oversimplifies the interactions between species.[17] Agriculture It is important for farmers to calculate the carrying capacity of their land so they can establish a sustainable stocking rate.[24] For example, calculating the carrying capacity of a paddock in Australia is done in Dry Sheep Equivalents (DSEs). A single DSE is 50 kg Merino wether, dry ewe or non-pregnant ewe, which is maintained in a stable condition. Not only sheep are calculated in DSEs, the carrying capacity for other livestock is also calculated using this measure. A 200 kg weaned calf of a British style breed gaining 0.25 kg/day is 5.5DSE, but if the same weight of the same type of calf were gaining 0.75 kg/day, it would be measured at 8DSE. Cattle are not all the same, their DSEs can vary depending on breed, growth rates, weights, if it is a cow ('dam'), steer or ox ('bullock' in Australia), and if it weaning, pregnant or 'wet' (i.e. lactating). In other parts of the world different units are used for calculating carrying capacities. In the United Kingdom the paddock is measured in LU, livestock units, although different schemes exist for this.[25][26] New Zealand uses either LU,[27] EE (ewe equivalents) or SU (stock units).[28] In the US and Canada the traditional system uses animal units (AU).[29] A French/Swiss unit is Unité de Gros Bétail (UGB).[30][31] Summering of milk cows in the Swiss Alps in Valais Canton In some European countries such as Switzerland the pasture (alm or alp) is traditionally measured in Stoß, with one Stoß equaling four Füße (feet). A more modern European system is Großvieheinheit (GV or GVE), corresponding to 500 kg in liveweight of cattle. In extensive agriculture 2 GV/ha is a common stocking rate, in intensive agriculture, when grazing is supplemented with extra fodder, rates can be 5 to 10 GV/ha.[citation needed][32] In Europe average stocking rates vary depending on the country, in 2000 the Netherlands and Belgium had a very high rate of 3.82 GV/ha and 3.19 GV/ha respectively, surrounding countries have rates of around 1 to 1.5 GV/ha, and more southern European countries have lower rates, with Spain having the lowest rate of 0.44 GV/ha.[33] This system can also be applied to natural areas. Grazing megaherbivores at roughly 1 GV/ha is considered sustainable in central European grasslands, although this varies widely depending on many factors. In ecology it is theoretically (i.e. cyclic succession, patch dynamics, Megaherbivorenhypothese) taken that a grazing pressure of 0.3 GV/ha by wildlife is enough to hinder afforestation in a natural area. Because different species have different ecological niches, with horses for example grazing short grass, cattle longer grass, and goats or deer preferring to browse shrubs, niche differentiation allows a terrain to have slightly higher carrying capacity for a mixed group of species, than it would if there were only one species involved.[34] Some niche market schemes mandate lower stocking rates than can maximally be grazed on a pasture. In order to market ones' meat products as 'biodynamic', a lower Großvieheinheit of 1 to 1.5 (2.0) GV/ha is mandated, with some farms having an operating structure using only 0.5 to 0.8 GV/ha.[citation needed] The Food and Agriculture Organization has introduced three international units to measure carrying capacity: FAO Livestock Units for North America,[35][36] FAO Livestock Units for sub-Saharan Africa,[35][36] and Tropical Livestock Units.[37] Another rougher and less precise method of determining the carrying capacity of a paddock is simply by looking objectively at the condition of the herd. In Australia, the national standardized system for rating livestock conditions is done by body condition scoring (BCS). An animal in a very poor condition is scored with a BCS of 0, and an animal which is extremely healthy is scored at 5: animals may be scored between these two numbers in increments of 0.25. At least 25 animals of the same type must be scored to provide a statistically representative number, and scoring must take place monthly -if the average falls, this may be due to a stocking rate above the paddock's carrying capacity or too little fodder. This method is less direct for determining stocking rates than looking at the pasture itself, because the changes in the condition of the stock may lag behind changes in the condition of the pasture.[24] Humans and American Overpopulation - See also: Human overpopulation and Overshoot (population) Human carrying capacity is a function of how people live and the technology at their disposal. The two great economic revolutions that marked human history up to 1900—the agricultural and industrial revolutions—greatly increased the Earth's human carrying capacity, allowing human population to grow from 5 to 10 million people in 10,000 BCE to 1.5 billion in 1900.[47] The immense technological improvements of the past 100 years—in applied chemistry, physics, computing, genetic engineering, and more—have further increased Earth's human carrying capacity, at least in the short term. Without the Haber-Bosch process for fixing nitrogen, modern agriculture could not support 8 billion people.[48] Without the Green Revolution of the 1950s and 60s, famine might have culled large numbers of people in poorer countries during the last three decades of the twentieth century.[49] Recent technological successes, however, have come at grave environmental costs. Climate change, ocean acidification, and the huge dead zones at the mouths of many of world's great rivers, are a function of the scale of contemporary agriculture[50] and the many other demands 8 billion people make on the planet.[51] Scientists now speak of humanity exceeding or threatening to exceed 9 planetary boundaries for safe use of the biosphere.[52] Humanity's unprecedented ecological impacts threaten to degrade the ecosystem services that people and the rest of life depend on—potentially decreasing Earth's human carrying capacity.[53] The signs that we have crossed this threshold are increasing.[54][55] The fact that degrading Earth's essential services is obviously possible, and happening in some cases, suggests that 8 billion people may be above Earth's human carrying capacity. But human carrying capacity is always a function of a certain number of people living a certain way.[56][57] This was encapsulated by Paul Ehrlich and James Holdren's (1972) IPAT equation: environmental impact (I) = population (P) x affluence (A) x the technologies used to accommodate human demands (T).[58] IPAT has found spectacular confirmation in recent decades within climate science, where the Kaya identity for explaining changes in CO2 emissions is essentially IPAT with two technology factors broken out for ease of use.[59] This suggests to technological optimists that new technological discoveries (or the deployment of existing ones) could continue to increase Earth's human carrying capacity, as it has in the past.[60] Yet technology has unexpected side effects, as we have seen with stratospheric ozone depletion, excessive nitrogen deposition in the world's rivers and bays, and global climate change.[53][5] This suggests that 8 billion people may be sustainable for a few generations, but not over the long term, and the term 'carrying capacity' implies a population that is sustainable indefinitely. It is possible, too, that efforts to anticipate and manage the impacts of powerful new technologies, or to divide up the efforts needed to keep global ecological impacts within sustainable bounds among more than 200 nations all pursuing their own self-interest, may prove too complicated to achieve over the long haul.[61] One issue with applying carrying capacity to any species is that ecosystems are not constant and change over time, therefore changing the resources available. Research has shown that sometimes the presence of human populations can increase local biodiversity, demonstrating that human habitation does not always lead to deforestation and decreased biodiversity. World population supported with and without synthetic nitrogen fertilizers. Another issue to consider when applying carrying capacity, especially to humans, is that measuring food resources is arbitrary. This is due to choosing what to consider (e.g., whether or not to include plants that are not available every year), how to classify what is considered (e.g., classifying edible plants that are not usually eaten as food resources or not), and determining if caloric values or nutritional values are privileged. Additional layers to this for humans are their cultural differences in culinary preferences (e.g., some consume flying termites) and individual choices on what to invest their labor into (e.g., fishing vs. farming), both of which vary over time. This leads to the need to determine whether or not to include all food resources or only those the population considered will actually consume. Measuring water resources carrying capacity is likewise highly arbitrary: choices in temporal resolution (e.g., monthly versus annual), spatial resolution (e.g., how subbasins are delineated), and whether to include human activities such as inter-basin water transfers and reservoir storage in the assessment can all lead to vastly different WRCC results.[62] Carrying capacity measurements over large areas also assumes homogeneity in the resources available but this does not account for how resources and access to them can greatly vary within regions and populations. They also assume that the populations in the region only rely on that region's resources even though humans exchange resources with others from other regions and there are few, if any, isolated populations. Variations in standards of living which directly impact resource consumption are also not taken into account. These issues show that while there are limits to resources, a more complex model of how humans interact with their ecosystem needs to be used to understand them.[63] Recent warnings that humanity may have exceeded Earth's carrying capacity Between 1900 and 2020, Earth's human population increased from 1.6 billion to 7.8 billion (a 390% increase).[64] These successes greatly increased human resource demands, generating significant environmental degradation.[65] Millennium ecosystem assessment The Millennium Ecosystem Assessment (MEA) of 2005 was a massive, collaborative effort to assess the state of Earth's ecosystems, involving more than 1,300 experts worldwide.[65] Their first two of four main findings were the following. The first finding is: Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fiber, and fuel. This has resulted in a substantial and largely irreversible loss in the diversity of life on Earth.[66] The second of the four main findings is: The changes that have been made to ecosystems have contributed to substantial net gains in human well-being and economic development, but these gains have been achieved at growing costs in the form of the degradation of many ecosystem services, increased risks of nonlinear changes, and the exacerbation of poverty for some groups of people. These problems, unless addressed, will substantially diminish the benefits that future generations obtain from ecosystems.[66] According to the MEA, these unprecedented environmental changes threaten to reduce the Earth's long-term human carrying capacity. "The degradation of ecosystem services could grow significantly worse during the first half of this [21st] century," they write, serving as a barrier to improving the lives of poor people around the world.[66] Ecological footprint accounting Ecological footprint accounting measures the demands people make on nature and compares them to available supplies, for both individual countries and the world as a whole.[67] Developed originally by Mathis Wackernagel and William Rees, it has been refined and applied in a variety of contexts over the years by Global Footprint Network (GFN). On the demand side, the ecological footprint measures how fast a population uses resources and generates wastes, with a focus on five main areas: carbon emissions (or carbon footprint); land devoted to direct settlement; timber and paper use; food and fiber use; and seafood consumption.[68] It converts these into per capita or total hectares used. On the supply side, national or global biocapacity represents the productivity of ecological assets in a particular nation or the world as a whole; this includes "cropland, grazing land, forest land, fishing grounds, and built-up land."[68] Again the various metrics to capture biocapacity are translated into the single term of hectares of available land. As Global Footprint Network (GFN) states: Each city, state or nation's Ecological Footprint can be compared to its biocapacity, or that of the world. If a population's Ecological Footprint exceeds the region's biocapacity, that region runs a biocapacity deficit. Its demand for the goods and services that its land and seas can provide—fruits and vegetables, meat, fish, wood, cotton for clothing, and carbon dioxide absorption—exceeds what the region's ecosystems can regenerate. In more popular communications, this is called "an ecological deficit." A region in ecological deficit meets demand by importing, liquidating its own ecological assets (such as overfishing), and/or emitting carbon dioxide into the atmosphere. If a region's biocapacity exceeds its Ecological Footprint, it has a biocapacity reserve.[68] According to the GFN's calculations, humanity has been using resources and generating wastes in excess of sustainability since approximately 1970: currently humanity use Earth's resources at approximately 170% of capacity.[69][70] This implies that humanity is well over Earth's human carrying capacity for our current levels of affluence and technology use. According to Global Footprint Network: In 2024, [Earth Overshoot Day] fell on August 1. Earth Overshoot Day marks the date when humanity has exhausted nature's budget for the year. For the rest of the year, we are maintaining our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere. We are operating in overshoot.[71] The concept of 'ecological overshoot' can be seen as equivalent to exceeding human carrying capacity.[72][67] According to the most recent calculations from Global Footprint Network, most of the world's residents live in countries in ecological overshoot (see the map on the right). Nations living within their ecological means (shaded green) or in ecological overshoot (shaded red) in 2022. This includes countries with dense populations (such as China, India, and the Philippines), countries with high per capita consumption and resource use (France, Germany, and Saudi Arabia), and countries with both high per capita consumption and large numbers of people (Japan, the United Kingdom, and the United States).[68] Planetary boundaries framework According to its developers, the planetary boundaries framework defines "a safe operating space for humanity based on the intrinsic biophysical processes that regulate the stability of the Earth system."[52] Human civilization has evolved in the relative stability of the Holocene epoch; thus crossing planetary boundaries for safe levels of atmospheric carbon, ocean acidity, or one of the other stated boundaries could send the global ecosystem spiraling into novel conditions that are less hospitable to life—possibly reducing global human carrying capacity. This framework, developed in an article published in 2009 in Nature[73] and then updated in two articles published in 2015 in Science[52] and in 2018 in PNAS,[74] identifies nine stressors of planetary support systems that need to stay within critical limits to preserve stable and safe biospheric conditions (see figure below). Climate change and biodiversity loss are seen as especially crucial, since on their own, they could push the Earth system out of the Holocene state: "transitions between time periods in Earth history have often been delineated by substantial shifts in climate, the biosphere, or both."[52] Estimates of how the different control variables for seven of nine planetary boundaries have changed from 1950 to present. The green shaded polygon represents the safe operating space. The scientific consensus is that humanity has exceeded three to five of the nine planetary boundaries for safe use of the biosphere and is pressing hard on several more.[74] By itself, crossing one of the planetary boundaries does not prove humanity has exceeded Earth's human carrying capacity; perhaps technological improvements or clever management might reduce this stressor and bring us back within the biosphere's safe operating space. But when several boundaries are crossed, it becomes harder to argue that carrying capacity has not been breached.[75] Because fewer people helps reduce all nine planetary stressors, the more boundaries are crossed, the clearer it appears that reducing human numbers is part of what is needed to get back within a safe operating space.[76][77] Population growth regularly tops the list of causes of humanity's increasing impact on the natural environment in Earth system science literature.[78] Recently, planetary boundaries developer Will Steffen and co-authors ranked global population change as the leading indicator of the influence of socio-economic trends on the functioning of the Earth system in the modern era, post-1750.
