Mylar and latex balloons are especially dangerous to the environment and community, according to the city council’s ordinance. The particular balloons can take up to four years to biodegrade, could cause power outages if contact is made with electrical lines, and may be harmful to wildlife if ingested or if the strings lead to entanglement.
Approximately 18,000 pieces of Mylar or latex balloons were collected during the Great Lakes cleanups between 2016 and 2018, according to the council. Alternatives to releasing balloons include blowing bubbles, spreading wildflower seed bombs, planting trees or flowers, and waving flags, council members suggested.
