Overexploitation in the context of "Overfishing"

Land consumption as part of human resource consumption is the conversion of land with healthy soil and intact habitats into areas for industrial agriculture, traffic (road building) and especially urban human settlements. More formally, the EEA has identified three land consuming activities:

1. The expansion of built-up area which can be directly measured;
2. the absolute extent of land that is subject to exploitation by agriculture, forestry or other economic activities; and
3. the over-intensive exploitation of land that is used for agriculture and forestry.

In all of those respects, land consumption is equivalent to typical land use in industrialized regions and civilizations.

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.

Land management is the process of managing the use and development of land resources. Those resources are used for a variety of purposes for example agriculture, forestry, water resource management, human settlements and tourism. One aim of land management is to prevent or reverse land degradation. Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff, and decreasing soil erosion. Unsustainable land managements leads to land being over- or misused which in turn degrades the land, reduces productivity and disrupts natural equilibriums.

Sustainable land management (SLM) is the set of practices and technologies that aim to integrate the management of land, water, and other environmental resources to meet human needs while ensuring long-term sustainability, ecosystem services, biodiversity, and livelihoods. Sustainable forest management is a sub-category of sustainable land management.

Overconsumption describes a situation where consumers overuse their available goods and services to where they cannot, or do not want to, replenish or reuse them. In microeconomics, this is the point where the marginal cost of a consumer is greater than their marginal utility. The term overconsumption is quite controversial and does not necessarily have a single unifying definition. When used to refer to natural resources to the point where the environment is negatively affected, it is synonymous with the term overexploitation. However, when used in the broader economic sense, overconsumption can refer to all types of goods and services, including artificial ones, e.g., "the overconsumption of alcohol can lead to alcohol poisoning." Overconsumption is driven by several factors of the current global economy, including forces like consumerism, planned obsolescence, economic materialism, and other unsustainable business models, and can be contrasted with sustainable consumption.

Defining the amount of a natural resource required to be consumed for it to count as "overconsumption" is challenging because defining a sustainable capacity of the system requires accounting for many variables. A system's total capacity occurs at regional and worldwide levels, which means that specific regions may have higher consumption levels of certain resources than others due to greater resources without overconsuming a resource. A long-term pattern of overconsumption in any region or ecological system can cause a reduction in natural resources, often resulting in environmental degradation. However, this is only when applying the word to environmental impacts. When used in an economic sense, this point is defined as when the marginal cost of a consumer is equal to their marginal utility. Gossen's law of diminishing utility states that at this point, the consumer realizes the cost of consuming/purchasing another item/good is not worth the amount of utility (also known as happiness or satisfaction from the good) they had received, and therefore is not conducive to the consumer's wellbeing.

The management of fisheries is broadly defined as the set of tasks which guide vested parties and managers in the optimal use of aquatic renewable resources, primarily fish. According to the Food and Agriculture Organization of the United Nations (FAO) in the 2001 Guidebook to Fisheries Management there is currently "no clear and generally accepted definitions of fisheries management". Instead, the authors use a working definition, such that fisheries management is:

The goal of fisheries management is to produce sustainable biological, environmental and socioeconomic benefits from renewable aquatic resources. Wild fisheries are classified as renewable when the organisms of interest (e.g., fish, shellfish, amphibians, reptiles and marine mammals) produce an annual biological surplus that with judicious management can be harvested without reducing future productivity. Fishery management employs activities that protect fishery resources so sustainable exploitation is possible, drawing on fisheries science and possibly including the precautionary principle.

Common goods (also called common-pool resources) are defined in economics as goods that are rivalrous and non-excludable. Thus, they constitute one of the four main types based on the criteria:

• whether the consumption of a good by one person precludes its consumption by another person (rivalrousness)
• whether it is possible to prevent people (consumers) who have not paid for it from having access to it (excludability)

As common goods are accessible by everybody, they are at risk of being subject to overexploitation which leads to diminished availability if people act to serve their own self-interests.

Tropical timber may refer to any type of timber or wood that grows in tropical rainforests and tropical and subtropical moist broadleaf forests and is harvested there. Typical examples of worldwide industrial significance include, among others, the following hardwoods:

• Chloroxylon
• Ebony
• Mahogany
• Narra
• Rosewood
• Teak

Overexploitation of those woods has led to widespread deforestation in the tropics. The intergovernmental organization International Tropical Timber Organization is concerned with conservation of the habitats of tropical timber trees.
