This is a picture of a drained canal in Paris. The Amsterdam canals are dredged regularly, but assumably it wouldn’t look much different here. In Amsterdam even a lot of junk coming from boats must be added – fuel tanks, (two-stroke) outboard motors, flawed fenders, pillows, paint, oil, etc. Every sunken boat with a motor and fuel on board is a little environmental catastrophy again.
We don’t know if junk and sunken boats will disappear, once people will only sail emmission free trough the canals. It will be an advantage though that al least water- and airpollution by petrol, diesel and oil would decrease. And who knows, people may also change their mindset towards the canals. A protective attitude could establish about this jewel they pass by daily.
