Pre-print. Letter to editor. Is livestock in agriculture an issue for climate? The case for disjunctive reasoning

Abstract. Some scholars keep pushing the factoid that animal source food is harming the climate - a five-factor complex few people know much about. Since the Cambrian period, Earth has gone through a multitude of climate changes. For the past million years, our ancestors have relied on an animal source diet to guarantee the >30 micronutrients they needed to survive with sustained brain development. That includes the mind's capacity for acceptance of viewpoint diversity, entrepreneurial exploratory thinking forward in time, epistemic vigilance, and metacognitive sensitivity in disjunctive reasoning.

In the special issue called Northern Agriculture in Changing Climate, the editor’s introduction states:
“Agricultural production has an ambivalent role with regards to climate change. It is both a source and a sink of greenhouse gases”.
Tiainen et al. (2020) wrote:
“Agriculture and especially cattle farming is under keen societal focus because of its significant role in soil carbon losses, greenhouse gas (GHG) emissions and biodiversity preservation”.
Ollikainen et al. (2020) wrote:
“Of all agricultural direct non-CO2 emissions, 80% are from livestock, with ruminants accounting for more than 80% of the total livestock emissions”.
Ferris et al. (2020) claimed that:
“Agriculture makes a significant contribution to global GHG emissions, with ruminant livestock systems known to be a significant source of emissions”
and concludes that there is little variation in CH4-emission between two dairy cow genotypes.

Climate is a systemic phenomenon explained by a complex interplay between atmospheric, hydrospheric, cryospheric, lithospheric, and biospheric components (IPCC, 2013). Since the Cambrian period, Earth has gone through a multitude of climate changes. For example, 2.6 Mya when the Pliocene epoch changed to Pleistocene, our ancestors relied on an animal source diet to guarantee the 30 micronutrients they needed to survive with sustained brain development (Aiello and Wheeler 1995, Mann 2018, Pobiner 2013, Pringle 2016, Thompson et al. 2018).

Archaeological findings show that after the introduction of agriculture, people who relied on a plant-based diet lost up to 15 cm in height (Koehler et al. 2017, Mummert et al. 2011). This phenomenon is still prevalent in some provinces in India and on the African continent (Adesogan et al. 2019, India, Country brief. 2020).

For the past 540 million years, a significant amount of atmospheric CO2 has been stored in the oceans, bedrock, and forests. Now, this CO2 is being released on a rapid scale. Globally livestock contributes 14.5% of global emissions (FAO). However, emissions from livestock in Finland only constitute 5% of the country’s total emissions (Nylund 2019) and this percentage is similar in all Nordic countries. Even so, taking animal source food of the plate will have no significant effect on the reduction of CO2 (White and Hall 2017).

CH4 (methane) is a significantly more potent GHG than CO2, but most CH4 released into the atmosphere is recycled into atmospheric CO2 within one decade. The carbon contained in biogenic methane is not new (or additional) to the atmosphere, but it cycles between CO2 and CH4 during processes of photosynthesis and hydroxyl oxidation - a process referred to as the Biogenic Carbon cycle (Global Carbon Project, Werth 2019).

Viewpoint diversity is important for the purpose of supporting entrepreneurial exploratory thinking forward in time (Kuratko 2017, Lerner and Tetlock 2002, Österberg 2012, Ploum et al. 2017). However, in order for prospects to be accurate, epistemic vigilance and metacognitive sensitivity in disjunctive reasoning are paramount (Koplak and Stanovich 2002, Pinker 2011, Sperber et al. 2010, Szpunar et al. 2014). This also holds true in science when dealing with issues such as the interplay between agriculture and climate. Also read: Frankelius (2020). Agriculture – a climate villain? Maybe not!
