How is it acceptable to simply send all that plastic into the air with no concern for where it ends up or the animals it impacts on

The balloon itself can be mistaken for jellyfish and eaten, the string can tangle and choke and the plastic valve used to keep the helium in is also a danger.

Blue Planet 2 has amply demonstrated that we have a plastic issue and by releasing balloons we are adding to this.

We should take the stance that it is no longer environmentally-acceptable to conduct a balloon release.
