I was at the southern end of Battersea Church Road recently, and a causeway
leading into the river was absolutely covered in rubbish. I am guessing that
Wandsworth Council is not responsible for cleaning anything below the high
water mark, and that rubbish builds up there until the next high tide takes
it back into the river. But the fact that rubbish builds up there makes it
an ideal place to remove the rubbish and prevent it getting back into the
river, so that it won't end up in the middle of the Pacific Ocean, where the
pile of rubbish is already ten times the size of England. So is anyone
responsible for de-littering causeways?
