Earlier this month, Lotte Corporation launched thousands of balloons into the air to mark the opening of its World Tower in Seoul. It was a beautiful sight, and a typical practice at such occasions. Balloons are released into the sky all the time: at weddings, ceremonies, parties; even at the nationwide candlelit rallies that called for former president Park Geun-hye’s ouster. Rising into the sky, balloons symbolize hope, joy and anticipation for the future. Unfortunately, they also litter and kill.
