Choosing Milk — Part 2
The Environmental Impact of Milk Production
In Part 1 of my Choosing Milk series, we explored the health implications of different types of milk. Now, we’ll dive into the environmental consequences associated with conventional milk production.
Most conventional milk originates from large-scale dairy farms, commonly referred to as megadairies or factory farms. These operations rely heavily on technology and consume significant resources such as fossil fuels, land, and water. With thousands of cows housed under a single roof, these farms contribute to global warming through various channels.
One significant factor is the production of feed for conventionally raised cows, predominantly consisting of soy, corn, and other grains. The extensive cultivation of these crops often involves deforestation, resulting in the removal of trees that play a crucial role in carbon sequestration. Additionally, the consumption of feed by dairy cows leads to the emission of methane and nitrous oxide—potent greenhouse gasses—through belching and flatulence.
In contrast, grass-fed dairy farming, particularly on small to medium-sized farms, offers a more sustainable alternative. Grazing cows on pasture eliminates the need for extensive transportation of feed and water, as these resources are readily available on-site. Moreover, the natural fertilization of pastures by cow manure promotes healthy soil, which further aids in carbon sequestration. By supporting grass-fed dairy production, consumers help mitigate the environmental impact of milk production and contribute to the fight against climate change.
When selecting milk, prioritize organic, grass-fed options to minimize your ecological footprint and promote sustainable farming practices
Look for these certifications on your Milk Carton to ensure that your dairy products align with environmentally conscious principles: Certified Grassfed by A Greener World, American Grassfed Association Grassfed Dairy and Certified Grass-Fed Organic Livestock Program by Organic Valley and Maple Hill
Purchasing dairy at farmer’s markets is one of my favorite ways to find grass-fed products. Plus, you’ll have an opportunity to talk to the farmer and learn how the cows are raised and what they are fed.
In the future, I’ll write about the value of being more connected to where our food comes from. This is one really nice way to do just that.
