Animal agriculture worldwide encompasses 83% of farmland (but only accounts for 18% of the global calorie intake), and the direct consumption of animals as well as over-harvesting them is causing environmental degradation through habitat alteration, biodiversity loss, climate change, pollution, and trophic interactions.

The environmental impacts of animal agriculture vary because of the wide variety of agricultural practices employed around the world. Despite this, all agricultural practices have been found to have a variety of effects on the environment to some extent.
Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices, which can have major environmental impacts. Bad management practices include poorly managed animal feeding operations, overgrazing , plowing, fertilizer, and improper, excessive, or badly timed use of ...
Proposed adaptations to climate change in livestock production include improved cooling at animal shelters and changes to animal feed, though they are often costly or have only limited effects. [8] At the same time, livestock produces the majority of greenhouse gas emissions from agriculture and demands around 30% of agricultural fresh water ...
Communities located near factory pig farms experience negative health and environmental effects due to several factors associated with industrial pig farming. One main issue that arises out of intensive animal agriculture is the waste that the huge number of animals produce.
Animal husbandry has a significant impact on the world environment. Both production and consumption of animal products have increased rapidly. Since 1950, meat production has tripled, whereas the production of dairy products doubled and that of eggs almost increased fourfold. [78] Meanwhile, meat consumption has nearly doubled worldwide.
Four-fifths of agricultural emissions arise from the livestock sector. [10]According to the 2006 Food and Agriculture Organization of the United Nations (FAO) report Livestock's Long Shadow, animal agriculture contributes on a "massive scale" to global warming, air pollution, land degradation, energy use, deforestation, and biodiversity decline.
