I wish there were more people who think like you, there are people that DO know the effects that it can cause on the enviroment, but they just don't care because "having fun" is more important. Yesterday I saw a heartbreaking image on facebook where a lot sea turtles died because they mistook plastic bags as jellyfish, it's up to us to raise awareness and educate people. I definitely say no to balloons and anything that destroys environment! Children need to grow up in a clean enviroment :)
