Climate Change and Rice: A Toxic Connection

Rice is a staple food for over half of the global population, but recent findings show that climate change may increase the levels of arsenic, a naturally occurring but harmful chemical, in rice. Arsenic can accumulate in the soil of paddy fields and enter rice grains, raising serious concerns for public health. Even small amounts of this carcinogen in food or water can lead to health problems such as cancer, diabetes, and heart disease. The amount of arsenic found in rice varies, but higher levels could become more common as the climate continues to change.
In a long-term experimental study, researchers grew 28 types of rice under different conditions and discovered that warmer temperatures and higher carbon dioxide levels caused more arsenic to build up in the plants. A leading epidemiologist involved in the study warned that these changes could result in millions of additional cancer cases if current rice consumption continues without action to reduce emissions. Although the research focused on China, the effects could be global, as arsenic is found in rice grown in many parts of the world.
