Washington: A new study has disclosed that rising levels of ozone as a result of the growing use of fossil fuels will harm planetary vegetation and give rise to grave costs to the world’s economic system.

The study is concentrated on how three environmental changes are related with human action, which impacts the crops, pastures and forests.

The analysis pointed that the rise in temperature and in carbon dioxide might really do well to vegetation, particularly in northern temperate areas.

But, those benefits might be more than offset by the detrimental effects of increases in ozone, notably on crops, the findings revealed.

The scientists said that Ozone, a form of oxygen, was an atmospheric toxin at the ground level.

The scientists performed their study by making use of the MIT Integrated Global Systems Model that combines linked high-tech economic, weather and farming computer models to cast greenhouse emissions and ozone precursors derived from human action and natural systems.

The researchers detected that the economic cost of the damage could be controlled by alterations in land use and by agricultural trade, with a few domains more capable of adapting as compared to the others.

But the overall economic outcomes would be substantial.

The scientists said if nothing is done, the international value of crop production would drop by 10-12% by 2100.

John M. Reilly, associate director of the MIT Joint Program on the Science and Policy of Global Change, said, “Even assuming that best-practice technology for controlling ozone is adopted worldwide, we see rapidly rising ozone concentrations in the coming decades.”

“That result is both surprising and worrisome,” Mr. Reilly said.

The study said, “What is the net effect of the three environmental changes? Without emissions restrictions, yields from forests and pastures would decline slightly or even increase because of the climate and carbon dioxide effects. But crop yields would fall by nearly 40 percent worldwide.”
