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.

Agriculture in Ireland began during the neolithic era, when inhabitants of the island began to practice animal husbandry and farming grains. Principal crops grown during the neolithic era included barley and wheat. Following the Acts of Union 1800, the majority of rural Irish workers participated in the agricultural sector of Ireland's economy.
Dairy cattle grazing in Germany. In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to free range (roam around) and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land that is unsuitable for arable farming.
Properly managed silvopasture (grazed woodland) can increase overall productivity and long-term income due to the simultaneous production of tree crops, forage, and livestock. It can provide environmental benefits, and has been practiced in many parts of the world for centuries. Silvopasture is not the same as unmanaged grazing in woodlands.
Livestock produces the majority of greenhouse gas emissions from agriculture and demands around 30% of agricultural freshwater needs, while only supplying 18% of the global calorie intake. Animal-derived food plays a larger role in meeting human protein needs, yet is still a minority of supply at 39%, with crops providing the rest. [93]: 746–747
Conservation grazing or targeted grazing [1] is the use of semi-feral or domesticated grazing livestock to maintain and increase the biodiversity of natural or semi-natural grasslands, heathlands, wood pasture, wetlands and many other habitats.
In Irish agriculture, the two most important greenhouse gases are methane and nitrous oxide. [8] 60% of Irish agricultural emissions come directly from animal agriculture, primarily as a result of methane-producing enteric fermentation from cattle. [8] A further 30% derive from soils fertilised by manures, synthetic fertiliser or animal grazing ...
A catt of the Bakhtiari people, Chaharmahal and Bakhtiari Province, Iran Global map of pastoralism, its origins and historical development [1]. Pastoralism is a form of animal husbandry where domesticated animals (known as "livestock") are released onto large vegetated outdoor lands for grazing, historically by nomadic people who moved around with their herds.
