The article "low water levels on Mississippi threatens shipping"  by Jim Salter and Jim Shur is about the Mississippi river becoming too shallow not enabling shipment overseas. This problem is causing shipping businesses to be in chaos and unable to make shipments across the country which can cause these businesses to crash. Head of marine operations Rick Calhoun said "You can’t just wait until it shuts down and suddenly say, ‘There’s a problem." the shallowness of the Mississippi river makes it impassable for barges carrying harvested crops. “The longer it lasts, the worse it gets,” said Don Sweeney associate director of the Center for Transportation Studies. The Mississippi river has a depth of 15 or 20 feet less than the normal depth of the Mississippi. The predominant concern is the stretch of the Missouri River near St. Louis and the Ohio River that are I which there is lack of rain and the normal width of 1000 feet is now a few hundred feet. The lowering of the Mississippi river can be cause because of global warming, mother nature, or because the pollution of the world. Most of the time a nature related issue comes up most people think that is because of time and global warning but if we accept that is because of the amount of pollution in the world we can see that it’s our fault. Air pollution causes less rain less rain causes less water to multiple. We need to cut down pollution and then maybe mother earth can provide us with what we need.
