Research shows that global climate change has reduced the ability to supply food. However, in most cases, these studies have neglected the interaction between elevated temperature and air pollution, especially ozone pollution, the impact of crop destruction. A new study by the Massachusetts Institute of Technology shows that the impact of climate may be significant, and policy makers need to consider both the issue of climate warming and air pollution.

The study evaluated four major global food crops: rice, wheat, corn and soybeans. They account for more than half of the world’s human calories burned. Due to population growth, food consumption is expected to increase by approximately 50% by 2050. Therefore, it is necessary to increase production by improving crops, improving farming methods, and expanding farmland. This prediction will vary greatly from region to region and crops will also differ. For example, wheat is very sensitive to ozone, and heat has a greater impact on corn. In general, under the same conditions for all other factors, by 2050 climate warming may reduce global crop production by about 10%. The impact of ozone pollution is more complicated, but its impact is very strong. At the same time, ozone pollution is also very difficult to identify because it is similar to other plant diseases such as discoloration and spotting of leaves.
Although heat and ozone can damage plants, various factors interact. For example, higher temperatures significantly increase ozone production, and organics and nitrogen oxides are more volatile in sunlight. Because of these interactions, the research team found that 46% of soybean crops previously attributed to thermal effects were actually caused by increased ozone. Pollution control measures can slow down the impact of production, and global output declines from the projected 15% to 9% due to emissions reductions.
Clean energy does not emit any greenhouse gas or conventional air pollutants. For example, the increase in the use of wind energy and solar energy will be beneficial to the safety of global food because they do not participate in any climate change or increase the concentration of ozone on the earth's surface.
