: Contemporary knowledge on climate change has given rise to a group of advocates who suggest global veganism as an adaptive means of mitigating the threat of climate change. Livestock farming is accused of contributing massively to greenhouse gas (GHG) emissions. Some studies suggest that eliminating meat from the diet (i.e., moving to a vegan diet) can reduce GHG emissions globally, while other studies suggest that livestock farming may make a smaller contribution to GHG emissions compared to previous estimates. A paradigm shift in agricultural production is expected to have direct impacts on natural resources, biodiversity, and economies. However, crop-only production and an exclusively vegan diet may lead to the loss of important plant and animal genetic materials, increase pressure on land and water resources, and exacerbate problems with agricultural crop residues. This “all in one basket” approach may affect the global meat trade, change the dynamics of some economies, and threaten food security in the event of pest and disease pandemics. This review found that crop-based ideology would make a huge contribution to reducing GHG emissions, while the integrity of land and water resources could be threatened in the future. Agricultural policies need to develop appropriate instruments to ensure food security, consumer preferences, and environmental protection and to provide a fair income for farmers worldwide. Global stakeholders in the agri-food sector, from policy makers to farmers, need to be engaged in a coherent policy to reduce the C footprint in our diets, protecting the (agri)environment and securing incomes.
