Tides have an ecological role to play. They cleanse the manmade pollutants. Nutrients if accumulated in excess will have a deleterious effect on plants. Urban pollutants are carried through rivers to the sea where marine organisms benefit.
Nature has a way of breaking up pollutants from piling up. Tides show how.
Bivalves and mud shrimps filter what they need while pollutants seep through tidal flats; during low tides it is an opportunity for marine birds to take their pick. These life forms help restoring a balance. Oneness is impartial in letting the results, both good and bad in human civilization, to spread around.
