Food and agriculture contribute one-third of global greenhouse gas emissions, second only to burning fossil fuels. In fact, a 2023 study published in science journal Nature found that greenhouse gas emissions from the way humans produce and consume food could add almost 1℃ of warming to the Earth’s atmosphere by the year 2100.
