The three foods that affect global warming the most
Greenhouse gas emissions are also linked to our food system, which needs to be completely overhauled if we want to protect the planet.
The way humans produce and consume food could add almost 1 degree of warming to the earth's climate by 2100. As a result, continuing to follow today's dietary patterns could push temperature increases beyond the predicted limit.
A new study, published in Nature Climate Change, is focused on analyzing how the production of different foods contributes to the emission of greenhouse gases.
The analysis estimated that if the level of food emissions continued as they are today, this would translate into at least 0.7°C of global warming by the end of the century.
But which foods "weigh" more in global warming?
According to the calculations of the new study, among foods, meat contributes 33% to global warming, rice 23% and dairy products 19%.
The production of these foods causes large amounts of methane to be emitted into the atmosphere, a powerful greenhouse gas that has more than 80 times the warming power of carbon dioxide.
The researchers in their study calculated that by 2030, methane will account for 75% of the warming due to food. Carbon dioxide, along with nitrogen oxide, will then make up the rest of the emissions.
