Jonny Magnusson from Helsingborg has been diving for over 30 years and has seen all kinds of rubbish on the seabed.
In recent times, he has collected what he found in a large pile.
- It is larger rubbish that I have not been able to pick up myself when I dive, he says.
Among other things, he found bicycles, car tires and rubbish bins.
This week it was time to lift up the rubbish heap - at the same time.
To succeed, he had to take the help of a crane truck.
- I'm a little nervous that the ropes will fall off, he says.
See what it looked like when the crane truck lifted all the rubbish out of the water in the clip above.
