But a new study warns that pollution caused by the world’s food production system is also a major driver of rising temperatures on the planet. The study found that if the world food system stays on its current growth path, it will produce nearly 1.4 trillion tons of greenhouse gases over the next 80 years. That pollution is expected to come from chemical fertilizers used in agriculture, mismanaged soil, food waste and methane (¼×Íé) gas released from cows and other animals.

Researchers from the University of Minnesota and the University of Oxford in Britain led the study, which recently appeared in the publication Science. The researchers predict that even if fossil fuel emissions (ÅÅ·Å) were halted now, emissions from the world food system would make it impossible to reach current international climate change targets. They say that emissions from food production alone could push world temperatures past 1.5 degrees Celsius by the middle of this century and above 2 degrees Celsius by the end of the century.

A main goal of the 2015 United Nations Paris Agreement on climate change is to keep rises in the Earth’s temperature during this century to between 1.5 to 2 degrees Celsius. The U. N. has said that in order to stay below the 1.5 Celsius level, emissions must fall at least 7.6 percent each year through 2030.

The new study calls for immediate improvements in farming practices, as well as changes in what we eat and how much food we waste to help reach the Paris Agreement goals.
