Animal agriculture contributes to global warming, which leads to ocean acidification. This occurs because as carbon emissions increase, a chemical reaction occurs between carbon dioxide in the atmosphere and ocean water, causing seawater acidification. [182] The process is also known as the dissolution of inorganic carbon in seawater. [183]
Intensive factory farming has grown to become the biggest threat to the global environment through the loss of ecosystem services and global warming. [105] It is a major driver to global environmental degradation and biodiversity loss . [ 106 ]
One paper estimated that if global warming reaches 2.5 °C (4.5 °F), then the cost of rearing broilers in Brazil increases by 35.8% at the least modernized farms and by 42.3% at farms with the medium level of technology used in livestock housing, while they increase the least at farms with the most advanced cooling technologies.
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.
Maize farming in Uganda is made more difficult due to heat waves and droughts worsened by climate change in Uganda. Out of the four crops, maize is considered the most vulnerable to warming, with one meta-analysis concluding that every 1 °C (1.8 °F) of global warming reduces maize yields by 7.4%. [10]
In 2020, it was estimated that the food system as a whole contributed 37% of total greenhouse gas emissions and that this figure was on course to increase by 30–40% by 2050 due to population growth and dietary change. [21] Between 2010 and 2019, agriculture, forestry and land use contributed between 13% and 21% to global greenhouse gas ...
The vulnerability of agriculture to climatic change is strongly dependent on the responses taken by humans to moderate the effects of climate change. [6] Changes in crop and livestock viability are forcing the farmers to find better choices of crops and animals, capable of adaption to temperature changes and water availability.
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area.
