Throwing beads at Mardi Gras poses environmental concerns primarily due to the materials used and the waste generated. Traditional Mardi Gras beads are often made from non-biodegradable plastics, contributing to plastic pollution when discarded improperly. These beads can end up in waterways, where they harm marine life and ecosystems. Additionally, the manufacturing process for beads consumes resources and may involve chemicals harmful to the environment. Moreover, the large-scale production and distribution of beads contribute to carbon emissions and energy consumption. 

Transitioning to biodegradable or reusable alternatives and promoting responsible disposal practices can mitigate the environmental impact of Mardi Gras celebrations but eliminating them all together and finding a new tradition is even better! Great move by Krewe of Freret | Mardi Gras New Orleans.
