Washington, June 7 : A new research has indicated that rising background levels of ozone in the atmosphere are a likely contributor to the global food crisis, since ozone has been shown to damage plants and reduce yields of important crop, including soybeans and wheat.

The research was conducted by William Manning of the University of Massachusetts Amherst in the US.

“Plants are much more sensitive to ozone than people, and a slight increase in exposure can have a large impact on their productivity,” said Manning.
