It's not that I'm cynical, *really*, but I look at huge landfills on terra firma... I look at our polluted rivers and lakes... and I can't help wondering how long it would take for the easiest path to be followed, for the sea-stead waste to be left to the ocean to "clean up". How long it would take for the last pristine corner of our planet to be infested with humankind and the detritus they bring with them.
It's not that I am cynical. But let's face it, our track record as a species... isn't great. Do we want to let ourselves loose on the oceans...?
