I really don't think, knowing what I now do know about the harm plastics do to the environment and to animals, that sending plastics up into the air in the form of balloons, is a good idea. Yes, I'm well aware that there are many, many other pollutants that we humans put out into this world of ours, but perhaps we can all do our bit to stop doing some of the harmful things - releasing balloons would be one thing we could do. I don't imagine there are many of us posting who have not suffered painful bereavements in our lives, and I can well understand how some things, be it lighting candles, releasing balloons, etc, can bring comfort to us. However, I really do think that with some things we do, however innocently, once their harm to the environment has been brought to our attention, then we really do need to look to alternatives. It's a pity there aren't biodegradable balloons and strings, isn't it? Perhaps there are? As it is, though, with most balloons and strings, the strings can entangle animals, and the plastic/latex can choke them - not nice, and totally avoidable.
