I was thinking the water eventually, mostly, makes it to the sea in any case. But, it probably reduces oxygenation of surface water (?) and maybe increases levels of chemical transfer from land to sea? I wouldn't expect either of those to be significant though.
Any thoughts on other possible effects, or is it just a general 'it's probably shit in a way we don't realise' feeling?
