How has the technosphere come to shape the Mississippi in its current formation? An excurse by geologist Peter K. Haff

In the criss-crossing of infrastructure that winds in and along the Mississippi, one can easily make out the manner in which technical systems have come to have a major impact on the flow, scale, and existence of the river. In this excurse, geologist Peter Haff discusses how the infrastructure embedded in the Mississippi demonstrates the salience of his own terming of planetary-scale technology: the technosphere.
