Overconsumption is a situation where resource use has outpaced the sustainable capacity of the ecosystem. A prolonged pattern of overconsumption leads to environmental degradation and the eventual loss of resource bases.
Generally, the discussion of overconsumption parallels that of human overpopulation; that is the more people, the more consumption of raw materials takes place to sustain their lives. However, humanity's overall impact on the planet is affected by many factors besides the raw number of people. Their lifestyle (including overall affluence and resource utilization) and the pollution they generate (including carbon footprint) are equally important. Currently, the inhabitants of the developed nations of the world consume resources at a rate almost 32 times greater than those of the developing world, who make up the majority of the human population (7.4 billion people).
However, the developing world is a growing market for consumption. These nations are quickly gaining more purchasing power and it is expected that the Global South, which includes cities in Asia, America and Africa, will account for 56% of consumption growth by 2030. This means that consumption rates will plateau for the developed nations and shift more into these developing countries.
The theory of overpopulation reflects issues of carrying capacity without taking into account per capita consumption, by which developing nations are evaluated to consume more than their land can support. The United Nations estimate that world population will reach 9.8 billion in the year 2050 and 11.2 in 2100. This growth will be highly concentrated in the developing nations which also poses issues with inequality of consumption. The nations that will come into consumer dominance must abstain from abusing certain forms of consumption, especially energy consumption of CO2. Green parties and the ecology movement often argue that consumption per person, or ecological footprint, is typically lower in poorer than in richer nations.
There is a spectrum of goods and services that the world population constantly consume. These range from food and beverage, clothing and footwear, housing, energy, technology, transportation, education, health and personal care, financial services and other utilities. Each of these require a different resource and once that resource is exploited to a certain point, that qualifies as overconsumption. Since the developing nations are rising quickly into the consumer class, it is important to note the trends happening in these nations. According to the World Bank, the highest shares of consumption lie in food, beverage, clothing, and footwear. This applies regardless of the sector of income.
Two main factors of why people buy so much and so often are due to planned and perceived obsolescence. This factor of production was introduced first in the United States and it revolves around the design of products. With these methods, the products are intentionally designed to be discarded after a short amount of time. As of 2012, only 1% of goods purchased were still in use after 6 months. When it is planned, designers create products that will not be able to work after a certain amount of time but they work for enough time to ensure the customers will come back to buy again. Perceived obsolescence comes in a lot with fashion and trends and fueled by advertising and media consumption. Through this technique, consumers are convinced that certain products do not have value anymore because it is out of style, and to have value, consumers must buy more up to date styles. As of 2015, the top five consumer markets in the world included the United States, Japan, Germany, China and France.
A fundamental effect of overconsumption is a reduction in the planet's carrying capacity. Excessive unsustainable consumption will exceed the long term carrying capacity of its environment (ecological overshoot) and subsequent resource depletion, environmental degradation and reduced ecosystem health. In 2020 multinational team of scientists published a study, saying that overconsumption is the biggest threat to sustainability. According to the study a drastic change in lifestyle is necessary for solving the ecological crisis. According to one of the authors Julia Steinberger: “To protect ourselves from the worsening climate crisis, we must reduce inequality and challenge the notion that riches, and those who possess them, are inherently good.” The research was published on the site of the World Economic Forum. The leader of the forum professor Klaus Schwab, calls to a "great reset of capitalism".
According to a 2020 study in which both population growth and deforestation were used as proxies for total resource consumption, if consumption continues at the current rate for the next 20–40 years, it can trigger a full or almost full extinction of humanity. To avoid it humanity should pass from a civilization dominated by the economy to a "cultural society" that "privileges the interest of the ecosystem above the individual interest of its components, but eventually in accordance with the overall communal interest"
The scale of modern life's overconsumption has enabled an overclass to exist, displaying affluenza and obesity. However once again both of these claims are controversial with the latter being correlated to other factors more so than over-consumption. Within the topic of overconsumption, many other ideas should be considered to find the true cause of it. Some important events that coincide are poverty, population and the development of an area. Overconsumption can also lead to a decline in the economy and financial instability.
In the long term, these effects can lead to increased conflict over dwindling resources and in the worst case a Malthusian catastrophe. Lester Brown of the Earth Policy Institute, has said: "It would take 1.5 Earths to sustain our present level of consumption. Environmentally, the world is in an overshoot mode."
As of 2012, the United States alone was using 30% of the world's resources and if everyone were to consume at that rate, we would need 3-5 planets to sustain this type of living. Resources are quickly becoming depleted, with about ⅓ already gone. With new consumer markets rising in the developing countries which account for a much higher percentage of the world's population, this number can only rise. According to Sierra Club’s Dave Tilford, "With less than 5 percent of world population, the U.S. uses one-third of the world’s paper, a quarter of the world’s oil, 23 percent of the coal, 27 percent of the aluminum, and 19 percent of the copper." According to BBC, a World Bank study has found that "Americans produce 16.5 tonnes of carbon dioxide per capita every year. By comparison, only 0.1 tonnes of the greenhouse gas is generated in Ethiopia per inhabitant."
A 2021 study published in Frontiers in Conservation Science posits that aggregate consumption growth will continue into the near future and perhaps beyond, largely due to increasing affluence and population growth. The authors argue that "there is no way—ethically or otherwise (barring extreme and unprecedented increases in human mortality)—to avoid rising human numbers and the accompanying overconsumption", although they do say that the negative impacts of overconsumption can perhaps be diminished by implementing human rights policies to lower fertility rates and decelerate current consumption patterns.
The Worldwatch Institute said China and India, with their booming economies, along with the United States, are the three planetary forces that are shaping the global biosphere. The State of the World 2005 report said the two countries' high economic growth exposed the reality of severe pollution. The report states that
The world's ecological capacity is simply insufficient to satisfy the ambitions of China, India, Japan, Europe and the United States as well as the aspirations of the rest of the world in a sustainable way.
In 2019, a warning on the climate crisis signed by 11,000 scientists from over 150 nations said economic growth is the driving force behind the "excessive extraction of materials and overexploitation of ecosystems" and that this "must be quickly curtailed to maintain long-term sustainability of the biosphere." Also in 2019, the Global Assessment Report on Biodiversity and Ecosystem Services published by the United Nations' Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, which found that up to one million species of plants and animals are at risk of extinction from human activity, asserted that
A key element of more sustainable future policies is the evolution of global financial and economic systems to build a global sustainable economy, steering away from the current limited paradigm of economic growth.
Effects on health
Overconsumption hurts the health of those who consume to much. For example, the food industry is large sector of consumption responsible for 37% of global greenhouse-gas emissions and studies show that people waste a fifth of food products just through disposal or overconsumption. By the time food reaches the consumer, 9% (160 million tons) goes uneaten and 10% is lost to overconsumption - meaning consumers ate more than the calorie intake requirement. When the consumer takes in too much, this not only explains losses at the beginning of the stage at production (and overproduction) but also lends itself to overconsumption of energy and protein, having harmful effects on the body like Obesity
A report from the Lancet commission says the same. The experts write: "Until now, undernutrition and obesity have been seen as polar opposites of either too few or too many calories," "In reality, they are both driven by the same unhealthy, inequitable food systems, underpinned by the same political economy that is single-focused on economic growth, and ignores the negative health and equity outcomes. Climate change has the same story of profits and power,". Obesity was a medical problem for people who overconsumed food and worked too little already in ancient Rome, and its impact slowly grew through history. As to 2012, mortality from Obesity was 3 times larger than from hunger, reaching 2.8 million people per year by 2017
Overuse of artificial energy, for example, in cars, hurts health and the planet. Promoting active living and reducing sedentary lifestyle, for example, by cycling, reduces greenhouse gas emissions and improve health
Overuse of screens can cause many diseases, among others depression, the leading cause of disability globally. It also responsible for significant greenhouse gas emission. As of 2018, 3.7% of global emissions were from digital technologies more than from aviation, the number is expected to achieve 8% by 2025, equal to the emissions from cars.
In September 2019, a day before the Global Climate Strike on 20 September 2019, The Guardian published an article that summarized several research papers and stated that overconsumption "Harms the health of big consumers: It can reduce empathy, reduce contact with other people, and more."
The idea of overconsumption is also strongly tied to the idea of an ecological footprint. The term "ecological footprint" refers to the "resource accounting framework for measuring human demand on the biosphere." Currently, China, for instance, has a per person ecological footprint roughly half the size of the USA, yet has a population that is more than four times the size of the USA. It is estimated that if China developed to the level of the United States that world consumption rates would roughly double. According to Scientific American, one person from China uses 53 times fewer resources than the average American.
Globalization and modernization has brought Western consumer cultures to countries like China and India, including meat-intensive diets which are supplanting traditional plant-based diets. More than 200 billion animals are consumed by a global population of over 7 billion annually. A 2018 study published in Science postulates that meat consumption is set to increase as the result of human population growth and rising affluence, which will increase greenhouse gas emissions and further reduce biodiversity. Meat consumption needs to be reduced by up to 90% according to a 2018 study published in Nature.
The most obvious solution to the issue of overconsumption is to simply slow the rate at which materials are becoming depleted. From capitalistic point of view, less consumption has negative effects on economies and so instead, countries must look to curb consumption rates but also allow for new industries, such as renewable energy and recycling technologies, to flourish and deflect some of the economic burdens. There are movements who think that reduction in consumption in some cases can benefit economy and society. They think that a fundamental shift in the global economy may be necessary to account for the current change that is taking place or that will need to take place. Movements and lifestyle choices related to stopping overconsumption include: anti-consumerism, freeganism, green economics, ecological economics, degrowth, frugality, downshifting, simple living, minimalism, and thrifting.
Recent grassroots movements have been coming up with creative ways to decrease the number of goods we consume. The Freecycle Network is a network of people in one's community that are willing to trade goods for other goods or services. It is a new take on thrifting while still being beneficial to both parties.
Other researchers and movements such as the Zeitgeist Movement suggest a new socioeconomic model which, through a structural increase of efficiency, collaboration and locality in production as well as effective sharing, increased modularity, sustainability and optimal design of products, are expected to reduce resource-consumption. Solutions offered include consumers using market forces to influence businesses towards more sustainable manufacturing and products.
Other ways to reduce consumption is to slow population growth by improving family planning services worldwide. In developing countries, more than 200 million women do not have adequate access. Women's empowerment in these countries will also result in smaller families.

Much less frequently mentioned are, however, the ultimate drivers of those immediate causes of biotic destruction, namely, human overpopulation and continued population growth, and overconsumption, especially by the rich. These drivers, all of which trace to the fiction that perpetual growth can occur on a finite planet, are themselves increasing rapidly.
