Humans and i know i´m generalizing but...
we´re really horrible and don´t care about any other crap but ourselves. i´ll admit i fall into that criteria i´m human to ... well duh.
i watched ´Happy Feet 2´and it got to me like for a month i tried to recycle and switch off lights and things i wasn´t using at a given time. but. it all faded away with time but everytime i remember i do stuff that matter.
my point is we´re all human, we all don´t care but when the time comes we´ll all pay for it and that´s when we´ll see that our Ipone´s and nasty smelly spray that´s filled with CFC´s , won´t really help us.
