Carbon Dioxide Influences Plant Disease

Researchers predict carbon dioxide will reach levels double those of the preindustrial era by the year 2050, complicating agriculture's need to produce enough food for a rapidly growing population.

Soybean plants growing in high carbon dioxide environments have denser canopies that can result in more disease problems. This seedling is showing signs of brown spot on its lower leaves. (

University of Illinois researchers are studying the impact of elevated carbon dioxide, elevated ozone and higher atmospheric temperatures on plant diseases that could challenge crops in these changing conditions.

So what brings to mind a science fair project that you can do that will influence your community to make shifts in the use of their cars, air conditioning and other pollutants?
