I have not made a post in a while but now i see this and im like another topic i should talk about. Okay so you probobally dont know this but i dont care that much about the enviroment one day its all gonna burn. Me and my siblings release balloons into the atmosphere all the time when were done with balloons we throw them off the deck and watch them go. One time when i was younger i got a balloon from going to somewhere and when i was heading back to the hotel i accidentally let it go i was really sad but now i wont hesitate to do it. This one was kinda short but i will make more soon but in conclusion no this will not affect the enviroment.
