The environmental impact of the global food system


The way we produce, process, transport, package, cook and dispose of food accounts for a major proportion of human-made greenhouse gas emissions. In fact, the global food system is responsible for up to one third of all emissions. This has a huge impact on the environment, and it is clear that we need to make changes in the way we produce and consume food if we want to reduce our carbon footprint. A first step would be to eat less meat and dairy, as these products have a particularly high carbon impact. Furthermore, choosing locally grown and seasonal produce, as well as reducing food waste, can also help to reduce the carbon footprint of the global food system.


The top 5 products with the highest emission exposed in the production process are Lamb,Beef,Cheese,Pork and Turkey with CO2 Equivalent 39.2 , 27 ,13.5 ,12.1 and 10.9 respectively. The research by greeneatz said that these products have a high impact on the environment due to the methane and nitrous oxide they produce during the digestion process which is 25 times and 298 times more potent than carbon dioxide respectively over a 100-year time frame. The report also concluded that animal agriculture is responsible for 18% of greenhouse gas emissions, more than the entire transportation sector combined. These numbers show that there is a significant environmental impact from the meat industry, and that it is important to be aware of the issue in order to make more environmentally friendly choices.

A low carbon diet is an eco-friendly diet consisting of foods that leave a minimal carbon footprint. The goal of the diet is to reduce the total greenhouse gas emissions produced by the food of which a person eats. A low carbon diet typically includes plenty of fruits, vegetables, and whole grains, as well as moderate amounts of lean protein. dairy, and healthy fats. Reducing your intake of processed foods, red meat, and refined sugars can also help to lower your carbon footprint. In addition to being good for the environment, a low carbon diet is also generally healthier for the human body. Eating plenty of fresh fruits and vegetables has been linked with a reduced risk of chronic diseases such as heart disease, cancer, and obesity.

With the global population expected to reach 9.7 billion by 2050, the demand for food will continue to increase. At the same time, the impact of climate change is making it more difficult to grow crops. As a result, there is a growing need for sustainable and eco-friendly sources of food. Insects are one such option. They require far less land and water than traditional livestock, and they emit fewer greenhouse gases. What's more, they are packed with protein, vitamins, and minerals. As the world looks for ways to become more sustainable, insect farming is likely to play an important role in meeting our future food needs.

One company that is taking advantage of these technologies is Exo, a cricket farm that produces a high-protein powder that is an ingredient in energy bars. The farm has installed a number of robots to help with tasks such as harvesting and sorting the crickets, and they have also deployed sensors throughout the facility to collect data that can be used to improve operations. Thanks to these technologies, the farm is forecast to make around 10,000 tonnes of the powder annually. Not only will this help Exo to meet the growing demand for their products, but it will also have a positive impact on the environment, as cricket farming requires far less water than other types of agriculture.
