As we near the end of our environmental law series, we turn to our beloved oceans. The Marine Protection, Research and Sanctuaries Act of 1972 also known as MPRSA, is one of several key environmental laws passed by the US Congress in 1972. The Act regulates the disposition of any material into ocean waters, unless expressly excluded under the MPRSA.  In this episode of our Environmental Law series, host Craig Williams is joined by Professor Robin Craig, the Robert C. Packard Trustee Chair in Law from USC Gould School of Law, as they discuss MPRSA, its origin & history, purpose, and impact.
