According to a recent report by Greenpeace, global animal production and consumption must decrease by 50 percent by 2050 to ensure planet and human health.
The report,Less is More: Reducing Meat and Dairy for a Healthier Life and Planet，讨论三个关键领域的肉类和乳制品生产和消费对：气候变化，环境和人类健康。它提出了生态农业，一种农业的方法，可以生产足够的食物，以在保护环境的同时，作为牲畜和农业生产的典范。
The report discusses the importance of reducing greenhouse gas emissions from livestock production to restrict global temperature increase to 1.5°C, in line with targets established in the2016年巴黎协定。牲畜的排放量占全球排放量的14％，而所有农业生产总额为24％。由于农业预计到2050年将占全球排放的52％，绿色和平组织说，肉类和乳制品生产减少了50％willreduce total agricultural emissions by 64 percent. To achieve the proposed 50 percent reduction, Greenpeace estimates that by 2050 annual consumption of meat should decrease to 16 kilograms per capita and annual consumption of dairy should decrease to 33 kilograms per capita.
除了温室气体排放外，肉类和乳制品消费量还以多种方式影响环境。绿色和平组织概述了与土地系统变化，生物多样性丧失，氮和磷的污染，淡水使用以及引入新物质有关的问题。动物产量占农业水足迹的29％，这是动物饲料的绝大多数。该报告发现，鉴于不同的生产投入和外部性，将一种肉代替另一种肉不一定对环境有益。
The report also discusses the human health risks associated with the consumption of red meat and processed meats. It explores the implications of studies on cancer, particularly colorectal cancer, metabolic syndromes such as obesity and diabetes, and cardiovascular disease. In addition, the use of antibiotics in livestock production contributes to antibiotic resistance in humans and promotes the spread of zoonotic diseases. Greenpeace advocates a shift to diets focused on vegetables, fruits, legumes, whole grains, and nuts to minimize personal and population health risk.
Based on the challenges that meat and dairy production and consumption pose on environmental and human health, Greenpeace calls on governments, businesses, and individuals to lead and support changes in policy and behavior. Éric Darier, Senior Agriculture and Food Strategist for Greenpeace, says: “The scientific evidence about the impacts on climate change, on massive loss of biodiversity and on threats to human health caused by livestock and meat consumption is overwhelming. We must act now!”
