Understanding The Environmental Impact Of Our Diet

Diet has been a buzzword for years now. Everyone seems to be wanting to change their diet to eat healthier and feel better. Diet means so much more, though, in an environmental aspect. It’s challenging to eat both healthily and sustainably when so many advertisements are filled with food on the opposite spectrum. Then again, there are conflicting views on what is healthy and sustainable.

So much of what humans eat has a negative environmental impact. From agricultural production to packaging and consumption, certain foods have more of an environmental influence than others.

What Is Sustainable Eating?

Sustainable eating focuses on limiting or eliminating foods that leave a huge carbon footprint on the environment. It involves consciously choosing foods that are good for both your body and the environment. This could look like eating more organically grown vegetables and limiting meats, especially beef or other red meats.

Understanding the environmental impact of our diets is an essential step toward sustainability in what we eat. Without the background knowledge of the carbon footprint of food production or the other ways it harms the world around you, you can’t fully appreciate or grasp what it means to eat eco-friendly foods.

Here are some ways our diet impacts the environment, from how food is grown to how it reaches your table.


Of all the carbon dioxide emissions in our atmosphere, agriculture accounts for about 10% of the total gases released. Plus, a good portion of the land once dominated by forests, shrubs and grassland is now used for agriculture, and that natural land is continuously diminished by farms.

Continual expansion of farmland changes the landscape and eliminates habitats for wildlife. This causes these animals to relocate, which then decreases biodiversity.

Additionally, farmland is used for producing feed for livestock. Corn and soy products dominate agricultural land, and they make up a large portion of the ingredients used in the things we eat. While they’re efficient products, the continuous, year-after-year growth of these crops depletes the land. Therefore, erosion occurs without a good erosion control strategy, and all the efforts are exhausted anyway.

Finally, non-organic agriculture uses fertilizers and pesticides that are harmful to the environment. These toxins enter streams and wildlife habitats, which can cause sickness, death or uninhabitable land.

Production And Shipping

After this food is grown, it has to be manufactured and shipped. This includes harvesting food with large equipment that uses fossil fuels. Furthermore, many of the foods you eat are probably not local. Therefore, the amount of energy it takes to ship them to your plate is immense, and more carbon emissions are released.

Plus, the food must be packaged during production. Some foods are packaged in plastics or non-recyclable materials. These plastics also release carbon dioxide, contributing to climate change.

Food Waste

Food waste is equally detrimental to the environment as agriculture and food production. In the United States alone, about 30%-40% of the food produced is wasted. It ends up in landfills and can never be brought back.

Often, this food waste results from spoilage. However, people and restaurants purchase way more than needed, or we end up getting rid of leftovers rather than eating them or storing them for later usage. Additionally, throughout the manufacturing process, various other factors cause food waste — rodents, insects, birds, bacteria or insufficient storage.

What You Can Do?

Fortunately, with a few changes in your diet, you can eat more sustainably. Keeping your health and the environment’s health at the forefront is the first step.

Besides that, try purchasing only what you need. Don’t buy and cook a ton of food if you know it will go to waste. If you do have leftovers you can’t eat, give them to someone in need. Limit your purchase of red meats and try to incorporate more fruits and vegetables into your diet. If you can, buy locally as well, so your food isn’t shipped as far.

Taking these small but significant steps can set you on the right track to lessening your carbon footprint and helping the planet.
