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.
They were probably also the first cattle bred mainly for milk production, with other breeds being developed mainly for draught and meat. The climate of southwestern Ireland was suitable for milk production year-round, and the Celts also stored milk in the form of cheese and butter.
Wolves were hunted in both Czarist and Soviet Russia with borzoi by landowners and Cossacks. [7] Covers were drawn by sending mounted men through a wood with a number of dogs of various breeds, [8] including deerhounds, staghounds and Siberian wolfhounds, as well as smaller greyhounds and foxhounds, [2] as they made more noise than borzoi.

It is responsible for somewhere between 20 and 33% of the fresh water usage in the world, [57] and livestock, and the production of feed for them, occupy about a third of Earth's ice-free land. [58] Livestock production is a contributing factor in species extinction, desertification, [59] and habitat destruction. [60]
The world-wide conservation status of the Dorset Horn was listed by the FAO as "not at risk" in 2007. [1]: 147 At country level, it is listed as "vulnerable" by the Rare Breeds Trust of Australia, [9] as "priority" by the Rare Breeds Conservation Society of New Zealand, [10] and as "threatened" by the Livestock Conservancy in the USA.
