Abstract
The research explored how air pollution, particularly high ozone levels, negatively impacts sensitive crops like wheat, rice, and soybeans, posing significant threats to global food security. It emphasized the long-overlooked destructive effects of ozone and emphasized the immediate need for strategies to counter these impacts amid climate change. Furthermore, the study examined the crucial role of increased carbon dioxide (CO2) levels on C4 crops, essential for global food security and biofuel production. Contrary to expectations, it challenged the belief that C4 crops inherently benefit from elevated CO2 levels in terms of enhanced photosynthesis. The study urged more experiments under changing climate conditions to refine predictions regarding crop yields. It emphasized the importance of focusing on ozone reduction, understanding how C4 crops respond to increased CO2, and assessing aerosol effects on specific crops. These insights aim to inform policies and strategies that can safeguard food security amidst rapid global economic growth and the challenges posed by climate changet.
