The frequency and intensity of natural disasters have been increasing over time and will continue to accelerate due to environmental degradation and global warming (FAO, 2015;Hallegatte & Przyluski, 2014;Thomas & López, 2015; World Bank, 2013). Natural disasters affect low-income countries more adversely than high-income or middle-income countries largely because of their poor infrastructure and institutions, which limit their ability to manage and withstand natural disasters. Moreover, since low-income countries are generally less diversified than their high-income counterparts, their post-shock economic resilience is relatively low (Laframboise & Loko, 2012). At the micro level, natural disasters are

“…However, the fact that is, for the most part, rationalized away by meat-eaters is that meat requires the slaughter and suffering of sentient beings (Singer, 1975(Singer, /2009. Also, meat production threatens the environment as it contributes a great deal to air pollution (Berners-Lee et al, 2012;Shafiullah et al, 2021), as well as pollution of water, soil, and deforestation (Thornton and Herrero, 2010). What is more, empirical evidence has accumulated that relates unfavorable health outcomes to a diet rich in meat (Tilman and Clark, 2014), in particular cardiovascular disease (Abete et al, 2014) and various types of cancer (Farvid et al, 2021) As plant-based diets can be related to a deficiency of micronutrients (Kristensen et al, 2015;Schüpbach et al, 2017;Haider et al, 2018), the exact quality of vegetarian/vegan diet is crucial.…”

Effects of experimentally induced self-affirmation on the openness to meat reduction and alternative protein sources

et al. 2023

IntroductionConsumption of animals entails disregarding the pain of sentient beings, and acknowledging this can threaten an individual’s image of oneself as a moral person. Also, abstaining from meat in a meat-eating culture can threaten an individual’s valued group identity. Previous research on inter-group relations suggests that self-affirmation, affirmation of personally or collectively important values, can help individuals alleviate self-threats since it enhances one’s global self-image and decreases threat perceptions.MethodsWe tested for potential effects of self-affirmation on openness toward reducing meat consumption in an experimental study. Participants (N = 277) were randomized into an individual affirmation, group affirmation, or a control condition. Individual affirmation participants ranked a list of values and then wrote a short paragraph about their first-ranked value. Group affirmation participants did a similar task, focusing on the values of their ethnic group, while participants in the control condition had an unrelated task of ranking their color preferences. Participants then read a persuasive message presenting health risks related to meat consumption and the health benefits of reducing meat. Finally, they indicated their openness toward reducing meat consumption and acceptability of plant-based alternatives and lab-grown meat.Results and DiscussionResults show that affirmed participants expressed more readiness to reconsider their meat consumption habits, reduced perceptions of vegetarianism as a threat to the local culture, and more positive perceptions of the idea of lab-grown meat. However, self-esteem and frequency of meat consumption pose important limitations to the experimental effects. We discuss the findings from the perspective of self-and collective identity threats and the potential of self-affirmations to create a more open debate about animal product consumption.

This study explored the combined effects of vitamin B12 and fumarate supplementation on methane (CH4) emission and propionate synthesis in dairy cows through simulated rumen fermentation in vitro. The experimental animals were 3 cows with an average milk yield of 23 ± 2.8 kg/d, a body weight of 618 ± 100 kg, and a parity of 3 ± 1 that were selected as rumen fluid donors. The TMR diet fed to cows is a fermentation substrate. Experiments adopted 2 × 2 factorial design, including control group, vitamin group (1 mg/g DM vitamin B12), fumarate group (100 mg/g DM), and combined addition group (1 mg/g DM vitamin B12 and 100 mg/g DM). All treatments had no effect on the dry matter degradation (DMD). Both vitamin B12 and fumarate reduced CH4 emission, increased the propionate concentration, and reduced the acetate/propionate ratio without any observed interaction. Vitamin B12 made Prevotella and Prevotellaceae_ UCG‐003 increase in quantity, and fumarate increased the abundance of Succinivibrionaceae_UCG‐002 and Selenomonas, both of which are propionate‐producing bacteria. At the species level, the supplementation of vitamin B12 and fumarate slightly changed the abundance of some strains, but it was not statistically significant. Shifts in the abundance of propionate‐producing bacteria and methanogenic archaea species suggest an increase in propionate production and a decrease in CH4 emission. In conclusion, the addition of vitamin B12 and fumarate changed the fermentation mode of the rumen and reduced the emission of CH4 by affecting the structure of the rumen microbial community, but no obvious interaction was found between the two.
