Meat consumption of all types is a major contributor to climate change and other environmental problems, but poultry and fish and aquatic invertebrates have lower environmental impacts than most other meats. To evaluate whether the growth in consumption of lower-impact meats has suppressed other meat sources, I analysed cross-national panel data for 1961–2013. I found that the increased consumption of poultry and fish and aquatic invertebrates has not suppressed the consumption of other meat sources.

家禽，鱼类和水生无脊椎动物尚未取代其他肉类来源

各种类型的肉类消耗量是导致气候变化和其他环境问题的主要因素，但与大多数其他肉类相比，家禽，鱼类和水生无脊椎动物对环境的影响较小。为了评估影响较小的肉类消费量的增长是否抑制了其他肉类来源，我分析了1961-2013年的跨国面板数据。我发现，家禽，鱼类和水生无脊椎动物的消费增加并未抑制其他肉类来源的消费。
