Balloons kill wildlife, pollute the earth and waste helium.

Balloons kill wildlife, pollute the earth and waste helium. Birds and turtles not only ingest balloons, they actively select them as food. This is because a burst balloon often resembles a jellyfish, the natural food sources of many marine species like turtles. Ingesting balloons, and the clips and strings attached to them, can cause intestinal blockages and results in a slow painful death through starvation.
Marine animals don’t have the gastrointestinal pH levels to breakdown a balloon and for turtles, it may also cause floating syndrome. Trapped gases in the gut can cause a turtle to become buoyant, unable to dive for food—making them vulnerable to boat strikes and leading to starvation and severe dehydration. Wildlife, both terrestrial and marine, can also become entangled in balloon ribbons or strings, causing injury or death through drowning, suffocation, or an inability to feed and avoid predators.
Sadly, nearly half of all seabird species are likely to ingest debris eating everything from balloons to glow sticks, plastic pellets, foam, metal hooks and fishing line. It has also been found that birds are collecting balloons and clips, thinking that it’s food, and feeding it to their young.
