於各種慶典不時會有放飛氣球的活動，這些氣球放飛後成為塑膠垃圾，造成大量污染，嚴重危害生態環境，特別是海洋生物及雀鳥，牠們會誤食或被纏繞至死。美國多個州分已立法管制或禁止放飛氣球。
Balloons are released from time to time at different celebrations and events. These balloons will turn into plastic waste and most of them end up on the ocean, polluting the environment. Wildlife especially marine animals and birds would mistake these marine debris as food or entangle to death. Some States in the US already set up legislation to control or ban releasing balloons.
