Animal's well-being, growth, and production are modulated by environmental conditions, and managemental practices and can be deleteriously affected by global warming phenomenon. In the recent years, unprecedented climatic fluctuations like sustained higher temperatures and humidity, heat waves, and solar flares have led to economic losses in $ billions to both milk and meat industry. It is estimated that by 2050, the US dairy industry alone will borne more than $1.7 billion loss. As human dependency on animal products like milk, meat, and eggs for nutrition is exponentially rising, there is urgency for maximum production. The high yielding animals are already under tremendous metabolic pressure making them more susceptible to adverse climatic conditions. When exposed to heat stress, livestock display a variety of behavioral and physiological acclimatization as essential survival strategies, but at the cost of decreased milk, meat, or egg production. Most of the studies have explored the heat stress in animals and its effect on different milk productions in a specific region or country. A clear understanding of the impact of global warming on dairy enterprise is yet to be comprehended. So this exploratory study will analyze impact of global warming on current milk production trends, economics, and future perspectives.
动物的福利、生长和生产受环境条件和管理实践的调节，全球变暖现象可能对其产生不利影响。近年来，持续升高的温度和湿度、热浪和太阳耀斑等前所未有的气候波动，导致牛奶和肉类行业遭受数十亿美元的经济损失。据估计，到 2050 年，仅美国的乳制品行业就将损失超过 17 亿美元。随着人类对牛奶、肉类和蛋类等动物产品的营养需求呈指数级增长，最大限度地提高产量迫在眉睫。高产动物已经承受着巨大的代谢压力，使它们更容易受到不利气候条件的影响。当暴露在热应激下时，牲畜会表现出各种行为和生理适应，这是必要的生存策略，但这是以降低牛奶、肉类或蛋类产量为代价的。大多数研究都探讨了动物的热应激及其对特定地区或国家不同牛奶产量的影响。然而，人们对全球变暖对乳制品企业的影响还没有清晰的认识。因此，这项探索性研究将分析全球变暖对当前牛奶生产趋势、经济和未来前景的影响。
