All right so there are some new reports this morning that pollution.

Maybe to think for the lush -- across our nation southeast.

It's a region and generally absorbs a little bit more carbon than it produces apparently -- but scientists fear that that could soon change.

What's.

Necessary is not in -- Atlanta Africa so pollution in helping the Faris doesn't sound like it adds up.

Yet seems counter intuitive and of course of all things that sound too good to be true there is a catch but according to this study by Auburn University.

The south has plenty of young four -- and as these young plants grow.

They -- -- huge amounts of carbon dioxide from the atmosphere according to the Auburn study published in the journal ecosystems.

Air pollution in the form of carbon and nitrogen.

Has served as fertilizer.

Over the years actually speeding the growth of these young -- listen.

He was shot -- couldn't you increase to come out he can.

But that -- not to come into formal.

Although the southeast leads the nation in reducing greenhouse gases the study's lead author -- and Sean.

Warns that the fertilization effects of carbon and nitrogen emissions are temporary and may soon be overshadowed.

By the damaging effects of other pollution pollutants such as ground level ozone especially as the region's urban centers continue to spread outward Martha so there's the catch.

Well there's a -- so what do researchers believe is a solution dollar this time and professor John believes that there needs to be careful urban planning and also air quality monitoring but he believes that with that in place.

These southern forests have the potential to maintain this region's.

-- it's enviable position of being the nation's leading carbon.

We do sir instead of going back to being a carbon producer Martha.

Very interesting --
