Overconsumption in the context of "Overshoot (population)"

Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, neoliberal economic policies and rapid economic growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species.

The term anthropogenic designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. The atmospheric scientist Paul Crutzen introduced the term "Anthropocene" in the mid-1970s. The term is sometimes used in the context of pollution produced from human activity since the start of the Agricultural Revolution but also applies broadly to all major human impacts on the environment. Many of the actions taken by humans that contribute to a heated environment stem from the burning of fossil fuel from a variety of sources, such as electricity, cars, planes, space heating, manufacturing, or the destruction of forests.

Environmental protection, or environment protection, refers to the taking of measures to protecting the natural environment, prevent pollution and maintain ecological balance. Action may be taken by individuals, advocacy groups and governments. Objectives include the conservation of the existing natural environment and natural resources and, when possible, repair of damage and reversal of harmful trends.

Due to the pressures of overconsumption, population growth and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960s, environmental movements have created more awareness of the multiple environmental problems. There is disagreement on the extent of the environmental impact of human activity, so protection measures are occasionally debated.

Resource consumption is about the consumption of non-renewable, or less often, renewable resources. Specifically, it may refer to:

• water consumption
• energy consumption
  • electric energy consumption
  • world energy consumption
• natural gas consumption/gas depletion
• oil consumption/oil depletion
• logging/deforestation
• fishing/overfishing
• land use/land loss or
• resource depletion and
• general exploitation and associated environmental degradation

Measures of resource consumption are resource intensity and resource efficiency. Industrialization and globalized markets have increased the tendency for overconsumption of resources. The resource consumption rate of a nation does not usually correspond with the primary resource availability, this is called resource curse.

Consumerism is a socio-cultural and economic phenomenon that is typical of industrialized societies. It is characterized by the continuous acquisition of goods and services in ever-increasing quantities. In contemporary consumer society, the purchase and the consumption of products have evolved beyond the mere satisfaction of basic human needs, transforming into an activity that is not only economic but also cultural, social, and even identity-forming. It emerged in Western Europe and the United States during the Industrial Revolution and became widespread around the 20th century. In economics, consumerism refers to policies that emphasize consumption. It is the consideration that the free choice of consumers should strongly inform the choice by manufacturers of what is produced and how, and therefore influence the economic organization of a society.

Consumerism has been criticized by both individuals who choose other ways of participating in the economy (i.e. choosing simple living or slow living) and environmentalists concerned about its impact on the planet. Experts often assert that consumerism has physical limits, such as growth imperative and overconsumption, which have larger impacts on the environment. This includes direct effects like overexploitation of natural resources or large amounts of waste from disposable goods and significant effects like climate change. Similarly, some research and criticism focuses on the sociological effects of consumerism, such as reinforcement of class barriers and creation of inequalities.

Paul Ralph Ehrlich (born May 29, 1932) is an American biologist, author and environmentalist known for his predictions and warnings about the consequences of population growth, including famine and resource depletion. Ehrlich is the Bing Professor Emeritus of Population Studies of the Department of Biology of Stanford University. Ehrlich became well known for the controversial 1968 book The Population Bomb, which he co-authored with his wife Anne H. Ehrlich, in which they famously stated that "[i]n the 1970s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now." This position has led historians and critics to describe Ehrlich as a neo-Malthusian.

There are mixed views on Ehrlich's assertions on the dangers of expanding human populations. While statistician Paul A. Murtaugh says that Ehrlich was largely correct, Ehrlich has been criticized for his approach and views, both for their pessimistic outlook and for the failure of his predictions. As of 2004, Ehrlich has acknowledged that population growth is in decline, but believes overconsumption by wealthy nations is a major problem. He maintains that his warnings about disease and climate change were essentially correct. Journalist Dan Gardner criticizes Ehrlich for his cognitive dissonance in forecasting, asserting that Ehrlich takes credit for his successful predictions but fails to acknowledge his mistakes.
