Mississippi River is a changing

Agriculture Changing Chemistry of Mississippi River says a report from the National Science foundation.

Apparantly farming is resulting in more water getting in the river, and also more carbon, which forms carbon dioxide. So now I guess we have to quit farming because it causes global warming.

Midwestern farming, and increased water flowing into the Mississippi River as a result, have injected the equivalent of five Connecticut Rivers' worth of carbon dioxide into the Mississippi each year over the last 50 years, according to a study published this week in the journal Nature.
The research is funded by the National Science Foundation (NSF).

"It's like the discovery of a new large river being piped out of the corn belt," said Peter Raymond, lead author of the study and an ecologist at Yale University. "Agricultural practices have significantly changed the hydrology and chemistry of the Mississippi."

The research team analyzed Mississippi River data as much as 100 years old. The data had been warehoused at two New Orleans water treatment plants....
