Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water. Meat is obtained through a variety of methods, including organic farming , free-range farming , intensive livestock production , and subsistence agriculture .
Air pollution caused by agriculture through land use changes and animal agriculture practices have an outsized impact on climate change. Addressing these concerns was a central part of the IPCC Special Report on Climate Change and Land [3] as well as in the 2024 UNEP Actions on Air Quality report. [4]

Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
This is an alphabetical list of environmental issues, harmful aspects of human activity on the biophysical environment. They are loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects.
Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment [36] (suspected of being one of the major causes of speciation [36]), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species.
Overgrazing by livestock can lead to land degradation. Land degradation is a process where land becomes less healthy and productive due to a combination of human activities or natural conditions. The causes for land degradation are numerous and complex. [1] Human activities are often the main cause, such as unsustainable land management practices.
Over 68 published and peer-reviewed studies have been conducted since 2002, out of these studies 15 found direct links to groundwater pollution from animals' waste at CAFOs. [5] Twelve of the studies made indirect links to water pollution and human health while seven found no link at all [6]
