Climate change is recognised as a significant public health issue that will impact on food security. One of the major contributors to global warming is the livestock industry, and, relative to plant-based agriculture, meat production has a much higher environmental impact in relation to freshwater use, amount of land required, and waste products generated. Promoting increased consumption of plant-based foods is a recommended strategy to reduce human impact on the environment and is also now recognised as a potential strategy to reduce the high rates of some chronic diseases such as cardiovascular disease and certain cancers. Currently there is a scant evidence base for policies and programs aiming to increase consumption of plant-based diets and little research on the necessary conditions for that change to occur and the processes involved in such a change. This paper reviews some of the environmental and health consequences of current dietary practices, reviews literature on the determinants of consuming a plant-based diet, and provides recommendations for further research in this area.
气候变化被认为是一个重大的公共卫生问题，将影响食品安全。导致全球变暖的一个主要因素是畜牧业，与植物性农业相比，肉类生产在淡水资源利用、所需土地面积和产生的废物方面对环境的影响要大得多。促进增加植物性食物的消费是减少人类对环境影响的推荐策略，现在也被认为是降低某些慢性疾病（如心血管疾病和某些癌症）高发率的潜在策略。目前，旨在增加植物性饮食消费的政策和计划的证据基础很少，关于发生这种变化所需的条件以及这种变化所涉及的过程的研究也很少。本文回顾了当前饮食实践的一些环境和健康后果，回顾了关于植物性饮食决定因素的文献，并为该领域的进一步研究提供了建议。
