well it is always changing
it has been and it is now and it still will be

i really wonder when the technology we invented will destroy us...

also have you guys heard of Ballard Fuel Cells?

for those u know, the byproduct is water
what if every car in the world 10 or 5 years from now all has fuel cells
and human uses it for 5 years

how much excess water would that be?
