Anthropocene

The Anthropocene is a proposed epoch dating from the commencement of significant human impact on the Earth's geology and ecosystems, including, but not limited to, anthropogenic climate change.

Biome

A biome is a community of plants and animals that have common characteristics for the environment they exist in.

New!!: Overpopulation and Biome · See more »

Carrying capacity

The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.

Coevolution

In biology, coevolution occurs when two or more species reciprocally affect each other's evolution.

Consumption (economics)

Consumption is the process in which consumers (customers or buyers) purchase items on the market.

Current Biology

Current Biology is a scientific journal that covers all areas of biology, especially molecular biology, cell biology, genetics, neurobiology, ecology and evolutionary biology.

Deer

Deer (singular and plural) are the ruminant mammals forming the family Cervidae.

New!!: Overpopulation and Deer · See more »

Desert

A desert is a barren area of landscape where little precipitation occurs and consequently living conditions are hostile for plant and animal life.

New!!: Overpopulation and Desert · See more »

Ecological footprint

The ecological footprint measures human demand on nature, i.e., the quantity of nature it takes to support people or an economy.

Ecological niche

In ecology, a niche (CanE, or) is the fit of a species living under specific environmental conditions.

New!!: Overpopulation and Ecological niche · See more »

Environment (biophysical)

A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution.

Epoch (geology)

In geochronology, an epoch is a subdivision of the geologic timescale that is longer than an age but shorter than a period.

New!!: Overpopulation and Epoch (geology) · See more »

Evolution

Evolution is change in the heritable characteristics of biological populations over successive generations.

New!!: Overpopulation and Evolution · See more »

Human impact on the environment

Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crises, and ecological collapse.

Human overpopulation

Human overpopulation (or population overshoot) occurs when the ecological footprint of a human population in a specific geographical location exceeds the carrying capacity of the place occupied by that group.

Immigration

Immigration is the international movement of people into a destination country of which they are not natives or where they do not possess citizenship in order to settle or reside there, especially as permanent residents or naturalized citizens, or to take up employment as a migrant worker or temporarily as a foreign worker.

Lemming

A lemming is a small rodent usually found in or near the Arctic in tundra biomes.

Lynx

A lynx (plural lynx or lynxes) is any of the four species (Canada lynx, Iberian lynx, Eurasian lynx, Bobcat) within the medium-sized wild cat genus Lynx.

Mortality rate

Mortality rate, or death rate, is a measure of the number of deaths (in general, or due to a specific cause) in a particular population, scaled to the size of that population, per unit of time.

Non-renewable resource

A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames.

Phys.org

Phys.org is a science, research and technology news aggregator where much of the content is republished directly from press releases and news agencies-in a practice known as churnalism.

Population

In biology, a population is all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.

New!!: Overpopulation and Population · See more »

Population decline

A population decline (or depopulation) in humans is any great reduction in a human population caused by events such as long-term demographic trends, as in sub-replacement fertility, urban decay, white flight or rural flight, or due to violence, disease, or other catastrophes.

Predation

Predation is a biological interaction where a predator (a hunting animal) kills and eats its prey (the organism that is attacked).

Quality of life

Quality of life (QOL) is the general well-being of individuals and societies, outlining negative and positive features of life.

Species

In biology, a species is the basic unit of classification and a taxonomic rank, as well as a unit of biodiversity, but it has proven difficult to find a satisfactory definition.
