This is wrong for three reasons:
1. Plastic balloons are an insidious form of marine pollutant, because once in the oceans they take on the role of “Food Mimic” – to many marine animals such as turtles, they are eaten because they look like their natural food.
2. This is against the law in Hong Kong - releasing balloons like this is an act contrary to the conditions of the Air Navigation (Hong Kong) Order 1995 (Notice of Mass Balloon Release).
3. It is encouraging the children in the protest to break the law and worse still, not consider the consequences of their actions.
