Decent enough flash.
Although I dont neccisarily agree with the idea you were trying to get across (The earth has been around for 4 billion years, we have been industrialized for only around 500. The earth will shake us off like a bad case of fleas before we become anything more than a "minor annoyance". Or, at least that's my take on it.) I liked the animation and sound well enough, but I cant bring myself to give it over a 5 simply because of lack of content. Now I dont mean to be downing you, but if you really broke your back to make a high quality flash (and I think your capible of it, just from looking at what you did produce) I would be willing to give it a 9 or a 10- regardless of the environmental message.
Now that I got all the negitivity out, here comes the praise: way to many people today walk around covered in a shroud of apathy. It's nice to see that you'r not like that, that you actually stand behind a cause. Even though the average environentalist annoyes me to some extent, I think their a damn sight better than the people that waste their time on this planet doin jack shit. If you dont stand for sometning, you'll fall for anything.
