Coal’s Slipping Grip: Death of a Georgia Coal Plant

The smokestacks, more than 800 feet tall, barely peek from behind the tall pines just across from Chester Allen's farm, but to him the damage from Plant Yates' coal is plain to see. "Dang-near everything rusts out early over here," said Allen, as he walked with his dog, Bogey, past a rusty disc harrow on the farm where he's lived for more than … Read More

A Green Alternative That Might Just Save the Planet

A Green Alternative That Might Just Save the Planet

Though important as greener alternatives to oil, many biofuels are produced from food crops, such as corn and sugar, which drives up global prices in a world where a billion people are already hungry.

8 Images to Understand the Drought in the Southwest

In states like Missouri, last summer’s drought was downright scary. Farmers saw their corn shrivel in the fields, ranchers ran out of feed for their cattle, and commerce on the Mississippi River slowed to a crawl, as barges struggled to avoid newly exposed rocks on the low-flowing river.

Crop Yields Inadequate to Feed the World by 2050: Study

If the world is to grow enough food for the projected global population in 2050, agricultural productivity will have to rise by at least 60 percent, and may need to more than double, according to researchers who have studied global crop yields. They say that productivity is not rising fast enough at present to meet the likely demands on agricultur… Read More
