Pellagra, a disease caused by a dietary deficiency in vitamin B (niacin), was seen in the southern United States after the Civil War (1861-65). In the early 1900s it was thought to be an infectious disease, but studies conducted by public health physician Joseph Goldberger at the Milledgeville State Hospital (later Central State Hospital) in Georgia showed that it was related to diet. Death statistics indicate that pellagra may have been one of the most severe nutritional deficiency diseases ever recorded in the United States.

Many types of soil and water pollutants that pose a serious risk to human and environmental health can be removed through a process known as phytoremediation. Phytoremediation is a type of bioremediation (the removal of toxins from the environment using microorganisms) in which plants are used to break down and remove unwanted or dangerous toxins and contaminants that might otherwise persist in the environment for hundreds or thousands of years.

Rat snakes (Elaphe obsoleta) are commonly found in wooded or swampy areas. Known as the "chicken snake" in farming areas because they will readily eat chicks and chicken eggs, rat snakes also enter barns in search of mice and rats. Like corn snakes, they are very good climbers.
