The Ethics of Eating Animals
The environment is inevitably strained by food production. Your daily food choices have a big impact on how sustainable your diet is overall. Not everyone wants to completely give up eating meat, despite the fact that vegetarian and vegan diets tend to be more environmentally friendly.
This article discusses how to consume both meat and plants more sustainably, as well as some of the main environmental effects of food production. Here’s a quick guide on how to be an ethical omnivore.
Food’s effect on the environment
Food production for human consumption has an impact on the environment.
As the world’s population grows, so does the demand for food, energy, and water, putting more strain on the environment.
Even though the demand for these resources cannot be completely eliminated, it is crucial to gain knowledge about them in order to make more sustainable food-related decisions.
Use of agricultural land
Land use is one of the primary agricultural factors that can be altered.
Land use has a significant impact on the environmental impact of food production because agriculture now occupies half of the world’s habitable land (1Trusted Source). More specifically, the majority of the world’s agricultural land is used to grow a few particular agricultural products like livestock, lamb, mutton, and cheese When grazing pastures and land used to grow animal feed are taken into account, livestock account for 77% of global farming land use However, they only account for 17% of the protein and 18% of the calories in the world Wild habitats are displaced as more land is used for industrial agriculture, causing environmental disruption.
Positively, agricultural technology has advanced significantly over the 20th and 21st centuries. As a result of this technological advancement, less agricultural land is needed to produce the same amount of food (4). Crop yield has increased per unit of land. Avoiding the conversion of forest land to agricultural land is one step we can take toward developing a sustainable food system (5). Joining a land preservation society in your area will help.
Treiber gases Approximately one-fourth of all greenhouse gas emissions are attributed to the production of food, which has a significant negative impact on the environment Carbon dioxide (CO2), methane, nitrous oxide, and fluorinated gases are the main greenhouse gases One of the main hypothesized causes of climate change is greenhouse gases
Livestock and fisheries make up 31% of the 25% that food production contributes, crop production 27%, land use 24%, and the supply chain 18% (2 Trusted Source). Your food choices can have a significant impact on your carbon footprint, which is the total amount of greenhouse gases a person causes, because different agricultural products contribute different amounts of greenhouse gases.

use of water
For the majority of us, water may seem like an endless resource, but there are many places in the world where there is a shortage of water. About 70% of freshwater use worldwide is related to agriculture (12). However, the amount of water used to produce various agricultural products varies. Cheese, nuts, farmed fish, and prawns are the products that require the most water to produce, followed by dairy cows (2Trusted Source). Therefore, adopting more water-efficient agricultural methods offers a great chance to do so. Using drip irrigation rather than sprinklers, collecting rainwater to water crops, and cultivating drought-tolerant plants are a few examples of how to do this.
nutrient runoff
Fertilizer runoff, also referred to as eutrophication, is the final significant effect of conventional food production that I want to touch on.When crops are fertilized, there is a chance that too many nutrients will end up in the surrounding area and waterways, disrupting natural ecosystems.Organic farming might seem like a potential answer to this, but that isn’t always Organic farming practices must not use artificial fertilizers or pesticides, but they do contain some chemicals.So, using organic products only partially resolves the runoff problems.However, research has shown that organic foods contain lower levels of pesticide residue than foods from conventional farms.
Although you as a consumer cannot influence farms’ fertilizer practices directly, you can promote more environmentally friendly alternatives, such as the use of cover crops and planting trees to control runoff.
Guidelines for eating sustainably
Here are some tips on how to eat more sustainably, including how much meat you should eat.
Does where you eat matter
Eating locally is a common suggestion for lowering your carbon footprint. Eating locally may seem intuitively sensible, but it doesn’t seem to have as much of an impact on food sustainability as you might expect — even though it might have other advantages. According to recent data, where food comes from is much less significant than what you eat because transportation only contributes a small portion of a food’s overall greenhouse gas emissions
This means that regardless of where the food has come from, choosing a food with lower emissions, like poultry, over one with significantly higher emissions, like beef, has a greater impact. However, buying locally may help you cut down on your carbon footprint when it comes to highly perishable foods, which must be transported quickly due to their short shelf lives. These foods are frequently transported by air, which significantly raises their overall emissions by up to 50 times more than shipping by sea (2 Trusted Source). These primarily consist of fresh produce like asparagus, green beans, berries, and pineapples.
It’s important to remember that only a very small portion of the world’s food supply is transported by air; the majority is shipped across the oceans or is driven by trucks. Nevertheless, there may be additional advantages to eating regionally, such as supporting small farmers who use more environmentally friendly farming methods, following the seasons, and knowing exactly where and how your food is grown.
moderate consumption of red meat
About 83% of our dietary emissions come from protein-rich foods like meat, dairy, and eggs. Beef and lamb have the highest carbon footprints of all food types. This is because they require a lot of land, have feeding needs, go through processing, and get packaged. Additionally, during the digestion process, cows produce methane in their guts, which adds to their carbon footprint. Other foods contribute significantly less to greenhouse gas emissions than red meat, which generates about 60 kg of CO2 equivalents per kg of meat (2Trusted Source). For instance, per kg of meat produced by poultry farming, 6 kg, 5 kg, and 4.5 kg of CO2 equivalents are produced.
In comparison, red meat, poultry, fish, and eggs have 132 pounds, 13 pounds, 11 pounds, and 10 pounds of CO2 equivalents per pound of meat, respectively. So reducing your red meat consumption can significantly reduce your carbon footprint. Although purchasing grass-fed red meat from ethical local producers may only slightly reduce greenhouse gas emissions, research indicates that reducing red meat consumption as a whole has a greater impact.
Consume more proteins from plants. Eating more plant-based protein sources is a powerful way to further the cause of being an ethical omnivore. When compared to the majority of animal proteins, foods like tofu, beans, peas, quinoa, hemp seeds, and nuts have a significantly lower carbon footprint (2Trusted Source). Protein content can be matched with the right portion sizes, even though the nutritional value of these plant proteins can vary greatly when compared to animal proteins. You don’t have to completely cut out animal products in order to increase your intake of plant-based protein sources. One way to cut back on your consumption of animal protein is to replace half of the protein in a recipe with plant-based protein.
The conclusion
Through land use, greenhouse gas emissions, water use, and fertilizer runoff, the production of food is a major contributor to global emissions. Eating more ethically can significantly reduce your carbon footprint, even though we can’t completely avoid this. Moderating red meat consumption, increasing the intake of plant-based proteins, and minimizing food waste are the main strategies for doing this. Making thoughtful food choices can significantly contribute to a sustainable food environment in the years to come
