Presidential candidate John Edwards’ wife Elizabeth is giving up tangerines to do her part to help global warming.

The politics of global warming got very concrete, and oddly difficult, in a meeting with local environmentalists in the coastal town of McClellanville today, where Elizabeth Edwards raised in passing the importance of relying on locally-grown fruit.

“We’ve been moving back to ‘buy local,’” Mrs. Edwards said, outlining a trade policy that “acknowledges the carbon footprint” of transporting fruit.

“I live in North Carolina. I’ll probably never eat a tangerine again,” she said, speaking of a time when the fruit is reaches the price that it “needs” to be.

What about other citrus fruits, a good source of vitamin C which is the only vitamin our bodies can’t store?

I live in S.C. and I know I can’t buy citrus here, so I’ll take the trucked-in variety of fruit or I’ll drive to Florida to buy it.

Then I’ll plant a tree to erase my carbon footprint.

Seriously, this global warming trend is becoming a religion to some people.

I’ll still be buying orange juice and citrus fruits from the market and I won’t worry about it at all.
