- I have built a fictional room at the bottom of the harbor basin, at a depth of about five meters. Everything is rubbish that I judged will not do any harm if it is left in the water for a while, says Jonny Magnusson.

Jonny has been scuba diving for over 30 years and the harbor pool at Pixlapiren is, perhaps a little unexpectedly, a popular place for many of the members of the diving club Delfinen.

- I have seen shoals of both herring and cod far into the harbor basin, but every year there is also more and more rubbish in the water, states Jonny Magnusson. I want more people to open their eyes to how we treat our oceans and their environments.
