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.
An important aspect of energy use in livestock production is the energy consumption that the animals contribute. Feed Conversion Ratio is an animal's ability to convert feed into meat. The Feed Conversion Ratio (FCR) is calculated by taking the energy, protein, or mass input of the feed divided by the output of meat provided by the animal.
Changes to a diet less reliant on animal products such as plant-based diets are also effective. [83]: XXV With 21% of global methane emissions, cattle are a major driver of global warming. [84]: 6 When rainforests are cut and the land is converted for grazing, the impact is even higher.
The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
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. [11]
Global warming may not just melt the polar icecaps and create a snowpocalypse previously only seen in 'The Day After Tomorrow.' Animals could 'shrivel' in size due to global warming, researchers ...
The bacteria and protozoans in the stomach of a reindeer break down lichen compounds into sugars that the animals use for sustenance. Reindeer need a lot of food to survive a long winter.
Methane is a strong greenhouse gas with a global warming potential of 86 compared to CO 2 over a 20-year period. [42] [43] As a by-product of consuming cellulose, cattle belch out methane, there-by returning that carbon sequestered by plants back into the atmosphere. After about 10 to 12 years, that methane is broken down and converted back to ...
