Balloons are a big part of the plastic problem that’s destroying our oceans & killing 100,000 marine mammals & 1 million birds every year. To a dolphin, whale, turtle, even a fish, balloons look like something to eat. They may be mistaken for a jellyfish, the sea turtle’s favorite food. But once they’re swallowed, balloons block an animal’s digestive tract and it can’t eat. They starve to death. Entangled in balloon streamers or twine they can’t move to hunt or surface to breathe.
Many individuals of non-target species perish as by-catch in the cast of each drift net. As a result, many such species are now endangered. Species caught as by-catch include sharks, dolphins, whales, turtles, sea birds, and other marine mammals. Since nets are placed and may not be retrieved for days, air-breathing mammals that become tangled in the nets drown if they are unable to free themselves.
