Celebrations, ceremonies and life events are important and can be great fun. But they can be lavish and often wasteful in terms of food, energy, materials and transport – the environment tends to be forgotten at such special times. So, act local, but think global.Balloons, their strings and labels, when let go of, fall back to earth and can be ingested by grazing animals, birds or marine creatures, so the Marine Conservation Society http://www.mscuk.org suggests we don't use balloons. So-called biodegradeable ones may take 4 years to disapper - that's not very biodegradeable, and they could do damage til then. And some scientists believe that the gas helium is too precious to be wasted in balloons.
Sky lanterns similarly cause fires and litter and sometimes havoc when they fall back to land. More and more councils are not allowing these to be let off on council land ,
http://www.balloonsblow.org has a few alternative ideas,
Glitter is made of micro-plastics, not yet banned, but some nurseries and schools have given up using them. (Lush has non-plastic glitter in their products )(You can find biodegradeable glitter made from eucalyptus, look online, various companies).
