140 Balloon during Earth Hour?? WTH??

Heard that the earth hour organiser in Penang is going to release a total of 140 balloons into the sky during the launching of the Earth Hour, WTH?? Do these people know bout the real issue here? 140 balloons, my goodness!! don't they know how much of polution is that move gonna make to the environment? Do we really need to do all more polution in order to gain publicity and to attract awareness?? Ok mayb the earth hour is for global warming, but how bout the other environmental issues? animal extinction? can u imagine that, 140 balloons alone in Penang and as far as i know not just Penang alone, other places will b doing the same thing as well. Where are all these so-called biodegradable balloons gonna end up by the end? even is gonna fly into the air, but sure it will fall back on Earth again and increase man made rubbish to the Earth. And what if some of this balloons that look like a jellyfish fall into the sea and ocean after inflated? sure it'll look like yummy food to 'choke' and killed the endangered turtles and whales, is not like it never happen b4 duh....Biodegradable?? my foot!! it'll at least take a few weeks (fastest) to few years to degrade, can u be sure that during that period of time, it wouldn't be eaten by those aquatic animals?? Pity them.
To the organiser, the Earth Hour is actually very meaningful and infact i'm so proud n happy to participate, not just light, i'll even switch off other electricals and restrain myself fr using PC and TV (it's my life, feel like dying without this 2), however, pls do things right!!! switching off our light for 60 mins is not enough to compensate for consequences of releasing 140 balloons to the environment.......!!!
