Human overpopulation

overpopulationexpanding human populationoverpopulated
Modifying the environment to fit the needs of society is causing severe effects, which become worse as the problem of human overpopulation continues.
Scientists suggest that the human impact on the environment as a result of overpopulation, profligate consumption and proliferation of technology has pushed the planet into a new geological epoch known as the Anthropocene.

Deforestation

deforestedland clearingforest clearing
Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include human reproduction, overconsumption, overexploitation, pollution, and deforestation, to name but a few. Some of the environmental issues that are related to agriculture are climate change, deforestation, genetic engineering, irrigation problems, pollutants, soil degradation, and waste. Conversely, according to some studies appearing in peer-reviewed journals, the growing demand for meat is contributing to significant biodiversity loss as it is a significant driver of deforestation and habitat destruction.
In many countries, deforestation–both naturally occurring and human-induced–is an ongoing issue.

Biodiversity

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 crisis, and ecological collapse.
Named the Holocene extinction, the reduction is caused primarily by human impacts, particularly habitat destruction.

Extinction event

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 crisis, and ecological collapse.
The mass extinction is considered a result of human activity.

Ecological footprint

environmental footprintfootprintecological footprints
It can be measured by the ecological footprint, a resource accounting approach which compares human demand on ecosystems with the amount of planet matter ecosystems can renew.
In short, it is a measure of human impact on Earth's ecosystem and reveals the dependence of the human economy on natural capital.

Climate change

climatic changeclimatechanging climate
Some of the environmental issues that are related to agriculture are climate change, deforestation, genetic engineering, irrigation problems, pollutants, soil degradation, and waste. The environmental impact of aviation occurs because aircraft engines emit noise, particulates, and gases which contribute to climate change and global dimming.
There is no general agreement in scientific, media or policy documents as to the precise term to be used to refer to anthropogenic forced change; either "global warming" or "climate change" may be used.

Environmental issue

Similar to other environmental issues, there can be conflict between the fishermen who depend on fishing for their livelihoods and fishery scientists who realize that if future fish populations are to be sustainable then some fisheries must reduce or even close.
Environmental issues are harmful effects of human activity on the biophysical environment.

Pollution

Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include human reproduction, overconsumption, overexploitation, pollution, and deforestation, to name but a few.
Growing evidence of local and global pollution and an increasingly informed public over time have given rise to environmentalism and the environmental movement, which generally seek to limit human impact on the environment.

Soil

An example of a means-based indicator would be the quality of groundwater that is affected by the amount of nitrogen applied to the soil.
Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological and anthropogenic processes working on soil parent material.

Holocene extinction

Conversely, according to some studies appearing in peer-reviewed journals, the growing demand for meat is contributing to significant biodiversity loss as it is a significant driver of deforestation and habitat destruction.
Ecologically, humanity has been noted as an unprecedented "global superpredator" that consistently preys on the adults of other apex predators, and has worldwide effects on food webs.

Overfishing

overfishedover-fishingfishing pressure
The environmental impact of fishing can be divided into issues that involve the availability of fish to be caught, such as overfishing, sustainable fisheries, and fisheries management; and issues that involve the impact of fishing on other elements of the environment, such as by-catch and destruction of habitat such as coral reefs.
Blue walleye became extinct in the Great Lakes in the 1980s. Until the middle of the 20th century, it was a commercially valuable fish, with about a half million tonnes being landed during the period from about 1880 to the late 1950s, when the populations collapsed, apparently through a combination of overfishing, anthropogenic eutrophication, and competition with the introduced rainbow smelt.

Wildlife

Humanity has caused the loss of 83% of all wild mammals and half of plants The world’s chickens are triple the weight of all the wild birds, while domesticated cattle and pigs outweigh all wild mammals by 14 to 1.
This subsection focuses on anthropogenic forms of wildlife destruction.

Sustainability

Similar to other environmental issues, there can be conflict between the fishermen who depend on fishing for their livelihoods and fishery scientists who realize that if future fish populations are to be sustainable then some fisheries must reduce or even close. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the pulp and paper industry.
Anthropogenic particulates such as sulfate aerosols in the atmosphere reduce the direct irradiance and reflectance (albedo) of the Earth's surface.

Greenhouse gas

greenhouse gasescarbon emissionsgreenhouse gas emissions
In addition, the combustion and thermal processing generate waste material, which must be disposed of, and harmful atmospheric emissions, including carbon dioxide, a major greenhouse gas.
The vast majority of anthropogenic carbon dioxide emissions (i.e., emissions produced by human activities) come from combustion of fossil fuels, principally coal, oil, and natural gas, with additional contributions coming from deforestation, changes in land use, soil erosion and agriculture (including livestock).

Water pollution

The environmental impact of the oil shale industry includes the consideration of issues such as land use, waste management, and water and air pollution caused by the extraction and processing of oil shale.
Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.

There is a growing gap between how many fish are available to be caught and humanity’s desire to catch them, a problem that gets worse as the world population grows.
Some analysts have questioned the sustainability of further world population growth, highlighting the growing pressures on the environment, global food supplies, and energy resources.

World Scientists' Warning to Humanity

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 term disclimax was used in-context by Clements (1936), and despite being an anthropogenic phenomenon which prevents the facilitation and succession to a true climax community, it is one of the only examples of climax that can be observed in nature.

I = PAT

I=PAT equation
The applications of technology often result in unavoidable and unexpected environmental impacts, which according to the I = PAT equation is measured as resource use or pollution generated per unit GDP.
I = PAT is the mathematical notation of a formula put forward to describe the impact of human activity on the environment.
