Clear Balloons
What goes up
must come down! Balloons return to the land and sea where they can be
mistaken for prey and eaten by animals. Balloons are hazards when they
enter the aquatic environment because they can look a great deal like
jellyfish—a major source of food for many animals. Sea turtles,
dolphins, whales, fish, and seabirds have been reported with balloons in
their stomachs. In 1985, an infant
sperm whale was found dead of starvation as a result of ingestion of
an inflated
Mylar balloon which had lodged in its intestines. Ribbons and
strings tied
to balloons can lead to entanglement.Latex rubber balloons
are an important category of product in the marine environment. Promotional
releases of balloons that descend into the sea pose a serious ingestion
and/or entanglement hazard to marine animals. Based on the fairly rapid
disintegration of balloons on exposure to sunlight in air, the expectation
is that balloons do not pose a particularly significant problem. In an experiment
we carried out in North Carolina we observed that balloons exposed floating
in seawater deteriorated much slower than those exposed in air, and even
after 12 months of exposure still retained their elasticity."
