====== livestock ====== 
Livestock functions as an actor in ANT. It neither generates pollution nor makes decisions. It acts as feedback from the actions of other actors, acting as a medium for transmitting non-biological influences.

Livestock mortality and metabolism serve as primary result feedback, revealing connections with other actors. Carcasses from natural deaths and partially slaughtered carcasses are transported to the **[[09|landfill]]** for disposal. Livestock from unnatural deaths may carry viruses into the **[[09|landfill]]**. Due to the **[[09|Doña Juana Landfill's]]** inadequate waste management practices, the odor from decomposing carcasses during **[[39|hot weather]]** impacts **[[14|nearby residents]]**, and this waste attracts large numbers of mosquitoes.(Gallini,2016) As virus carriers, these mosquitoes can lead to widespread infectious diseases.**[Fig.1]** Unnatural livestock deaths are primarily caused by disease and **[[39|climate change]]**. In recent years, widespread **[[39|high temperatures]]** in Colombia caused by climate change have reduced animal intake and growth rates while increasing mortality(Tapasco et al. 2019). As described in Sara(2025), livestock deaths also result from drinking **[[38|water]]**(**[[34|tunjuelo_rive]]**) polluted by leachate leaking from nearby **[[09|landfills]]** or being bitten by virus-carrying mosquitoes.  Meanwhile, viruses from sick livestock feces are carried by **[[26|soil]]** or **[[31|rivers]]**, or dispersed into the **[[01|air]]** by wind. This chain of effects contributes to large-scale infections. (Highly Pathogenic Avian Influenza, typhoid fever, and dysentery)(Stefania et al. 2014).

“Land of Plenty: Twice the size of Texas, Colombia houses nearly 10% of the Earth’s plant and animal species, with many concentrated in the Andean mountains and Amazonian rainforest.”(Palmer,2020)

“From Forest to Field: The Nature Conservancy is helping Colombian farmers implement sustainable ranching practices. On Farm Rosania in Cubarral, Meta, living fences of native plants contain cattle and can also connect forest to protected areas, which creates corridors for wildlife.”(Palmer,2020)

Livestock farming, a vital sector of Colombia's economic development, is currently facing challenges. Traditional livestock practices have led to **[[26|soil]]** and **[[34|river]]** degradation while contributing to the **[[39|climate change]]**(Action Landscape,2020).**[Fig.2]** In recent years, efforts have been made to transform traditional agricultural practices through technological innovation. This approach protects the local ecological environment while ensuring local economic development and reducing employment pressures in the region(Palmer,2020). **[Fig.3]**
