Environmental Effects of the Livestock Industry: Knowledge, Attitudes, and Behavior among Students
Abstract Background The livestock industry has numerous impacts on the environment. The aim of this study is to examine the level of knowledge, awareness and behavior on topics related to environmental pollution caused by industrial animal food production and to determine whether there is a relationship among them. Methods Cross-sectional study using an online questionnaire. 361 students were asked about their knowledge, attitudes, and behavior related to the environmental impact caused by livestock industry. The data were analyzed using correlations, t-tests for independent samples, and linear regression models. Results Students have almost no knowledge about the environmental impact of livestock industry, their attitudes are moderately pro-environmental, yet they are not strict about them. Students with higher levels of environmental knowledge demonstrated more pro-environmental attitudes and behavior (r = 0.33, p < 0.001; r = 0.36, p < 0.001 respectively); attitudes mediate the relationship between level of knowledge and behavior with respect to environmental pollution caused by the livestock industry (Adj. R2 =0.28, p < 0.001). Significant differences were found between participants who rear animals and participants who don't, in the level of knowledge (t = 3.78, p < 0.001), attitudes (t = 3.04, p < 0.01), and behavior (t = 2.33, p < 0.05). Conclusions These findings are in line with other studies, which showed that some consumers are concerned about production of animal foods but their knowledge on this topic is very limited, and most continue to consume animal products without any intention of reducing consumption. There is a need to raise awareness of the environmental and health impacts caused by livestock industry. An introductory course on environmental science should be integrated into different academic study programs. Further research should be conducted among additional population sectors. Key messages Students have almost no knowledge about the environmental impacts of the food they consume. There is a need to develop campaigns to raise awareness of environmental impacts of food.
