In 1910, Louisiana congressman Robert F. Broussard proposed the "American Hippo Bill" to introduce imported common hippopotamus from Africa to the Lousiana bayou, both to clear out the invasive water hyacinth and as a source of meat (the US being in the midst of an ongoing beef shortage at the time). Despite a broad degree of public support, however, the bill was never passed and the issue eventually died down as beef production increased. What would the ecological and economic consequences of this plan being passed and implemented have been?
