Global warming refers to the long-term rise in Earth’s surface temperature, particularly since the pre-industrial era (1850–1900). This phenomenon is mostly caused by human activity, such as the burning of fossil fuels, which raises the concentrations of heat-trapping greenhouse gases in the atmosphere. Carbon dioxide, methane, nitrous oxide, and water vapor are examples of greenhouse gases. Approximately 25% of greenhouse gas emissions come from food systems such as livestock. Most people don’t know that their dietary preference directly affects global warming.

Prior to industrialization, the majority of people relied on seasonal and locally sourced foods. However, the emergence of factory farming and industrial agriculture during the 20th century has changed how food is produced and consumed. These systems emphasize mass production, often prioritizing financial gain and efficiency over environmental sustainability. The dramatic rise in meat consumption worldwide, especially of red meats like lamb and beef, has had a significant effect. Large volumes of land, water, and feed are needed to produce these meats, which results in habitat loss, deforestation, and high energy consumption. Furthermore, methane, a powerful greenhouse gas that speeds up global warming, is produced in large quantities by ruminant animals like sheep and cows. The food system is now one of the main causes of climate change as a result of these changes in eating habits.

The total quantity of greenhouse gases produced by human activity is known as the carbon footprint. One possible way to reduce our carbon footprint is to change our diet and eating preferences. Due to the negative impact of meat-based food and diets, people also think about trying to eat plant-based food and reducing red meat consumption as well. For example, instead of consuming only red meat as a protein source, people can try fish, lentils, and other beans. Here is an example of how individuals can make an impact. Changing to vegetarian food one day a week for a year could save 1,160 miles of driving. But to have an effect, you don't need to follow a strict vegetarian or vegan diet. You can significantly reduce your carbon footprint by consuming less carbon-intensive animal products, like chicken and fish. For instance, it would save 993 miles of driving if all beef consumption were changed to chicken for a year. Also, preferring local vegetables or fruits instead of imported ones, such as tropical fruits, can help reduce the carbon footprint.

Diets aren’t just personal preferences; they are powerful environmental decisions. By making simple changes in daily habits, such as reducing red meat consumption and preferring local, plant-based foods more often, individuals can lower their carbon footprint and prevent climate change.
